VAR in V.League: When the Screen Cannot Replace the Referee's Eye

Minute 78, the score was 1-1. The referee put his hand to his earpiece, then walked toward the monitor by the touchline. The stands fell silent. Eleven away players gathered around the technical area, fingers pointed at the big screen. A home player stood two meters away, hands on hips, eyes fixed on every slow-motion frame. This image has become familiar in V.League in recent seasons — the moment a challenge inside the penalty area is split into multiple frames, slowed down, zoomed in, and then interpreted by a single person using the language of the law. I sat in the press area, earpiece still carrying a colleague's commentary, but my mind kept circling one question: when all of us look at the same thing, are we actually thinking about the same thing? The truth is that the screen does not create justice. It only places human beings in a different position, where the answer comes later, more carefully weighed, but is never easier. And for someone like me, who records matches through a data-obsessed eye, this is the gateway into a larger story: how the Vietnamese refereeing system actually operates when the law is clear but the person holding the whistle remains the biggest variable. I have followed Vietnamese professional football for eleven years, from the days as a contributor to a local radio station, to writing live match reports for a sports site in Shenzhen. Over those eleven years, Vietnamese football has changed enormously: better players, better pitches, more diverse broadcasting, and referee controversies have migrated from the stands into an air-conditioned room where the VAR cabin sits. This is not an exercise in criticism. It is a long record, with data, context, and a framework for counter-argument. I write as a referee observer who believes the law is never ambiguous. The ambiguity lies with people. And to understand why, we need to start from the beginning. The first context is technological. VAR was introduced into the V.League not to replace referees, but to reduce clear and obvious errors in four categories: goals, penalty decisions, direct red cards, and mistaken identity. These are the four categories written explicitly in the Laws of the Game by the International Football Association Board. Any referee entering the cabin must know these limits by heart. Beyond them, VAR has no right to intervene. But in Vietnam, the issue lies in the gap between the law and its application. A handball situation, judged in normal context, might be waved away by an assistant referee standing twelve meters away. When placed on a screen, enlarged fifty times, slowed to a quarter speed, it becomes clearer. But that does not mean the decision becomes easier. It only means the situation is placed in a different interpretive context. And this detail, over the past season, has become a systemic point of dispute. Here, I want to tell a memory. In 2026, when I was nineteen, I was interning at an online football website in Shenzhen. The opening match of the FIFA U-20 World Cup between France and Saudi Arabia finished 2-0. I wrote a live report and misspelled the name of striker Amine Gouiri four times in the first half. My editor corrected it and reprimanded me strictly. After the match, I spent two weeks reviewing all group-stage footage, memorizing the exact names and shirt numbers of one hundred and twenty players. The first mistake is not there to be erased; it is there to be cross-checked later. Since then, I have built my own FIFA-standard pronunciation table for player names, checking at least twice before publication. That approach may sound extreme against the speed of news, but with VAR, I realized something similar. Every refereeing decision disputed today becomes reference data for a similar situation tomorrow. That means every time a referee puts his hand to his earpiece, he is joining a historical chain. No one in the VAR cabin is allowed to forget that. That is the foundation. From here, I want to split the analysis into two great axes: the tactical axis and the management axis. These two axes intersect at a single point — the pitch. The tactical axis, for me, begins with a dry but telling metric: PPDA, the number of opponent passes allowed per defensive action. The lower the number, the higher the press. In the last three matches of one of the V.League title contenders, PPDA fell from 11.4 to 8.9. That sounds positive, but it comes with a consequence: the defensive line must push higher, the space behind the full-backs grows larger, and challenges inside the penalty area increase. More challenges mean more VAR reviews. This is not speculation. It is the direct consequence of a tactical choice. A high defensive line is a bet; I only record the moment the gambler shows his cards. And when those cards are shown inside the penalty area, the referee must decide within seconds. Last season, I followed a match in which the home side pushed up in a high press, led 1-0, and then lost 1-2 within the final seven minutes. Two of those conceded goals came from situations in which home defenders had to pull opponents inside the box. The referee awarded a penalty in one. VAR checked and upheld it. The stands roared. And I, in the press area, wrote just one line: "Minute 84, penalty. VAR check: decision upheld. Handball, right-back position, ball came in from the left." One line. But to understand that line takes an entire system of law and psychology. Here, I want to be clear. Same situation, two ways to blow the whistle — the law is never ambiguous, only the person holding the whistle is. I am not saying Vietnamese referees are poor. I am saying the pressure on Vietnamese referees is very specific, different from that in Europe. In Europe, a referee can be criticized in the press but has a professional support system of mentors, psychologists, and a transparent evaluation mechanism. In Vietnam, referees often work in an environment where errors are remembered longer than achievements are credited. To prove this, I want to cite a historical figure. Between 2026 and 2026, Vietnam's FIFA-listed referees ranged from four to six. Meanwhile, domestic professional matches each season hovered around two hundred, excluding youth and international matches. The referee-to-match ratio is very low. That means a small group of people bears a heavy workload. When the workload is heavy, errors appear more often. When errors appear more often, fan trust declines. That spiral is no one's individual problem. It is a structural one. And VAR, in that context, is not a miracle. It is a supplementary tool, best operated when there are enough trained personnel, a transparent evaluation process, and a culture that accepts referees as human beings. I believe in the naked eye, but VAR taught me that the naked eye also knows how to lie. The naked eye sees a player fall and immediately thinks penalty. The naked eye sees an arm and immediately thinks foul. But the naked eye cannot see the referee's angle, the true speed of the ball, the exact moment the foot lands. That is why VAR exists. Not to replace the eye, but to supplement it. However, I want to push the analysis in a different direction, one rarely discussed in Vietnam: the relationship between VAR and player psychology. When a player knows every challenge in the box will be reviewed, his movement inside the box changes. No more reckless defending in the "if he blows, he blows" style. Instead, players tend to fall more often, because they know the cameras will record and the referee can be fooled by exaggeration. This is a paradox. VAR was designed to reduce errors, but in some cases it creates an incentive for players to exploit errors more subtly. Last season, I recorded at least seven situations in which a player fell in the box, the referee did not award a penalty, VAR checked, and concluded there was no foul. Seven situations in one season is not a small number. But more notable is how fans reacted. In each situation, half the stands booed and half applauded. The same image, two interpretations. This is precisely the point where the law can never fully resolve. Because the law resolves the event, while emotion resolves honor. That is why I want to spend the next section on finance and the transfer market — an aspect rarely placed beside refereeing controversy in Vietnam, but in fact closely related. Look at how V.League clubs spend. Between 2026 and 2026, total transfer spending by top V.League clubs rose considerably, though most deals remained under one million US dollars. But the notable point is not the number — it is the spending structure. A club spends heavily on the attack, less on defense, and very little on referee development. Clubs, of course, are not obliged to train referees. But when refereeing quality cannot keep pace with the league's growth, the pressure falls on the very matches in which clubs have invested millions of dollars. A concrete example: a match decisive for an Asian competition spot may involve combined squad values exceeding ten million US dollars. But the referee in charge may earn only a few million Vietnamese dong. I am not making a salary comparison. I am pointing out an imbalance. When the value of a match result rises, pressure on refereeing decisions rises too, while resources to prepare referees lag behind. This is a formula for error. In the two-thousand-word analysis I wrote in 2026 as a student, about the inconsistency of substitution rules across leagues, I spent one hundred and twenty hours reviewing ten Bundesliga matches where the five-substitution rule applied. I found an average of 3.2 substitutions per match between minutes 60 and 75. That figure helped me understand that five substitutions deepen a squad but turn the final twenty minutes into a war of attrition. When fresh legs face a player who has run eleven kilometers, challenges naturally increase. More challenges mean more reviews. Since then, whenever I watch a match, I always place two numbers side by side: substitutions after minute 60, and VAR interventions. The correlation between them is no accident. The five-substitution rule opens a new battlefield in the final twenty minutes. It is the moment when a high line must choose between pressing on and dropping back to protect the score. It is also the moment when the referee must make the heaviest decisions. I often tell colleagues: to judge a referee's true form, don't look at the first ten minutes, look at the last twenty. In Vietnam, V.League clubs have gradually adapted to this rule, though application is uneven. Some use all five changes to intensify late pressure. Others use only two or three because of thin squads or fear of breaking structure. This difference creates a diverse tactical landscape, but also a difference in how many situations VAR must intervene. This is one of the points that, if analyzed carefully, could raise the quality of refereeing. But I want to return to the management axis, because this is the decisive one. The question I often ask when watching a match with VAR intervention is: who makes the final decision? Legally, the answer is clearly the main referee. In practice, the answer is more complex. In many situations, the main referee runs to the pitchside monitor, watches three or four frames, and comes back with a different decision. But in many others, the VAR team in the cabin reaches its own conclusion, and the main referee merely confirms. The difference between these two handling methods lies in how much intervention the VAR team permits itself. The problem is that in Vietnam, the standard process has not been fully communicated. Fans do not know when the VAR team has the right to reach a conclusion and when it can only ask the referee to review. Fans do not know how many frames may be reviewed. Fans do not know who sits in the cabin and who bears responsibility for the final decision. This ambiguity is not in the law. The law is clear. The ambiguity lies in communication and fan education. This is why I believe Vietnamese football needs a step no league in the region has taken thoroughly: public disclosure of VAR cabin conversations after each match, in summary form. Not to criticize, but to educate. When fans know the VAR team reviewed three frames, cross-checked the definition of the foul under Law 12, and weighed position and speed, dissatisfaction declines. Not because the decision was right, but because it was explained. Here, I want to tell a story. In 2026, I worked at a major sports site in Shenzhen, following the World Cup quarterfinal between Portugal and Morocco, which ended 0-1. Morocco broke Portugal's press, with each player running an average of 11.4 kilometers per match. I spent forty-eight hours reviewing footage and analyzing the 4-1-4-1 shape, writing a three-thousand-five-hundred-word piece, but my editor asked me to cut it to one thousand five hundred words because readers needed fast information. I learned to condense data into five key points and publish within two hours. That lesson applies directly to how I view VAR. A refereeing decision, right or wrong, only has explanatory value when it is presented concisely, clearly, with data and legal cross-reference. Saying "the referee was right" convinces no one. Saying "the VAR team reviewed three frames, cross-checked Clause 3 of Law 12 on holding, and determined the defending player touched the ball first" begins to build trust. This is not easy. It requires a professional communications mechanism, a staff with enough time, and a culture that accepts error as part of the process. But it is something Vietnamese football can do, and should do. Now I want to address another aspect many fans overlook: the institutional and legal context. Discipline exists not to punish, but so the match can continue. This sounds simple, but it is the foundational principle of the entire football law system. Every rule — from a yellow card for time-wasting to a dismissal for serious foul play — serves one goal: to let the match take place under the fairest conditions possible. When VAR was introduced, it did not change that goal. It only changed the tool. But in Vietnam, there is a systemic issue: a lack of synchronization across competition levels. The V.League uses VAR. The First Division does not. Youth tournaments do not. This means a referee may work a V.League match with VAR on Saturday, then a First Division match without VAR on Sunday. This transition demands high adaptability, and I am not certain all referees are trained for it. Moreover, the pandemic period of 2026-2026 taught me that laws also need to breathe. When leagues were suspended, when schedules were scrambled, when players had to play three matches in seven days, substitution rules were adjusted. UEFA allowed five substitutions, but the Premier League kept three. That inconsistency showed that even the largest organizations cannot apply laws mechanically. Laws must be read in context. In Vietnam, the pandemic also produced similar adjustments. But the point I want to make is not the specific adjustment detail, but a larger lesson: when laws change, a mechanism for explanation and adaptation is needed. Otherwise, the gap between law and reality becomes fertile ground for controversy. I want to move to a purely tactical aspect, because this is where I spend the most time observing. In modern football, V.League clubs are gradually shifting from a counter-attacking style based on physicality toward a more organized possession game. This is a positive trend, but it comes with a tactical consequence rarely discussed: sideways and backward passes increase. When sideways passes increase, ball-in-play time decreases. When ball-in-play time decreases, direct challenges decrease. This sounds good for refereeing. But in reality, the opposite happens: when challenges decrease, each remaining challenge becomes more important, and the pressure on the referee rises accordingly. I recorded a concrete example. In a home match of a title-contending club, the home side controlled 62 percent of possession, made nearly seven hundred passes, but produced only eight shots. The away side controlled 38 percent, made just over three hundred passes, but produced twelve shots. In the second half, there was exactly one challenge inside the box. The referee awarded a penalty. VAR checked and upheld it. The match ended 1-1. Home fans left feeling robbed of three points. But on reflection, the home side made seven hundred passes yet took only eight shots. That is a tactical problem, not a refereeing problem. But that is how fans remember it. This is why I always say refereeing controversy is a social phenomenon, not merely a legal one. People tend to remember what causes loss and forget what does not. A team that controls poorly but wins is praised. A team that controls well but concedes a penalty is seen as a victim. This is psychology, not law. And this is the point where I want to move to the management and dressing-room aspect. Dressing-room psychology directly affects how players react to refereeing decisions. A team with a calm coach usually has calm players. A team with a reactive coach has reactive players. Last season, I noted several situations in which coaches ran into the technical area, reacting strongly to the fourth official, while the main referee was reviewing the monitor. Such situations not only affect the match but set a precedent for future matches. Here, I want to cite a specific fact. In a recent season, yellow cards for coaches and staff in the V.League rose considerably. This is an indicator that pressure on referees comes not only from fans but from those on the bench. When pressure rises, referees tend to choose the safe option — blowing more. But blowing more does not mean blowing better. It only means more stoppages. I want to push the analysis to an aspect rarely mentioned: the relationship between VAR and youth football. When a young player grows up in an environment without VAR, then enters the V.League with VAR, he must relearn how to defend. This is a time-consuming process. In countries with solid youth systems, VAR is simulated from youth level. In Vietnam, this is not common. The result is a cognitive gap: young players do not understand that behaviors in the box once overlooked can now be reviewed. This is a systemic issue, and it directly affects the quality of V.League matches. When young players enter the top division, they carry habits from youth football. Those habits can lead to unnecessary challenges, and thus VAR reviews. Let me be clear: I am not proposing VAR in youth football. That is too costly and unnecessary. I am proposing educating young players about VAR thinking from the moment they learn the laws. That is, when teaching a young defender how to mark inside the box, also teach him that his action will be viewed from a different angle. This is a change in educational thinking, not in the law. And here, I want to address an aspect I consider most important but least discussed: the risk of over-reliance on VAR. When VAR becomes an indispensable part of the league, everyone starts to believe it can fix every error. But that is not true. VAR only handles four categories. It does not handle a second yellow card. It does not handle a wrong throw-in. It does not handle an offside in midfield if it does not lead to a goal or penalty. This means many errors remain and will continue to remain. If fans do not understand these limits, they will constantly feel wronged. Moreover, when VAR becomes the focus, pressure on the main referee rises, while pressure on assistant referees falls. This creates an imbalance in responsibility. An assistant who misses an offside in midfield will be criticized less than a main referee who upholds a decision after reviewing VAR. This is a psychological issue, but it affects the quality of work. I want to share a personal story. At a V.League match I observed, I sat beside a retired assistant referee. He told me something I will never forget: "Years ago, we decided in a fraction of a second. Now, we wait for three minutes. Those three minutes are much longer than a fraction of a second." That remark made me think. VAR gives referees more time to think, but it also gives them more time to doubt. Doubt is an uncomfortable psychological state. And when a person works in doubt, the ability to make decisive calls declines. This is an interesting paradox. The more technology supports, the more humans may hesitate. And that is why I believe psychological training for referees is as important as legal training. I want to move to the media and expectation aspect. Vietnamese football media has a distinct trait: it is very close to fan emotion. A controversial refereeing decision is often placed on the front page, with an emotionally charged headline. This has the advantage of generating great interest, but the disadvantage of creating an environment where referees find it hard to explain accurately. When media chooses an emotional frame, fans receive an emotional frame. When media chooses a legal frame, fans receive a legal frame. This is an editorial choice, not a legal one. In a previous article, I proposed that every match with VAR intervention should have a public technical summary afterward, listing the situations reviewed, the conclusions, and the legal cross-reference. That summary need not be long. It must be accurate. For example: "Minute 63: Checked a possible offside before the goal. Conclusion: no offside, attacker level with the red-shirt defender. Goal awarded." Such a summary helps fans understand that referees are not guessing. But to achieve this, a coordination mechanism among the organizer, the refereeing committee, and the media is needed. This is something the V.League could pilot, and if successful, it could be applied across the region. Now I want to address a final aspect, perhaps the one with the widest reach: the impact on the football industry. When fan trust in referees declines, the consequence is not confined to a single match. It sits across the entire football value chain. Fans do not buy tickets to watch a game they believe is rigged. Sponsors do not pour money into a league whose fairness is doubted. Broadcasters do not pay rights fees for a product with reputational risk. That is, refereeing controversy, if unhandled, can affect the revenue of the entire system. This is why I believe reforming refereeing is not a purely technical matter. It is part of a football development strategy. A V.League with well-trained referees, professionally operated VAR, and a transparent explanation mechanism will attract more fans, more sponsors, and more young talent. Conversely, a V.League where every round brings a new controversy will gradually lose public attention. I want to tell a story from my own experience. In 2026, I hosted the program "Football Night" for about four years and also worked as a producer. During that time, I learned something books do not teach: fans do not need to know everything. They only need to know they are respected. When a program clearly explained a refereeing decision, fan feedback was more positive. When a program only reported controversy without explanation, feedback was more negative. This is a lesson Vietnamese football can apply to VAR communication. I have spent much time on what is incomplete. Now I want to talk about what can be done. First, every VAR intervention should be archived as a technical record, including frames, review time, conclusion, and legal cross-reference. This record should be made public in summary form, so fans, players, and coaches can reference it. The first mistake is not there to be erased; it is there to be cross-checked later. Every controversial situation becomes valuable data for a similar situation in the future. Second, referee training should be extended to lower levels, including youth, not to apply VAR, but to teach VAR thinking. A young defender needs to understand his actions will be seen from multiple angles. A young striker needs to understand simulation will be reviewed. This is part of modern football education. Third, the relationship between VAR and substitution rules needs further study. When substitutions increase, the last twenty minutes become the most challenge-heavy period. If the correlation between substitutions and VAR interventions can be identified, organizers can adjust scheduling, referee staffing, or review procedures accordingly. Fourth, referee psychology should stand equal to referee skill. A referee strong in law but weak in psychology will struggle to decide under stadium pressure. A proper psychological training program, with expert participation, will help referees be more stable in decisive moments. Fifth, communication should shift from an emotional frame to a legal frame. This does not mean removing emotion. Emotion is part of football. But when controversy arises, an explanation of the law must be added. An article about a controversial decision should contain at least one paragraph cross-referencing a specific clause. This is how to raise fan understanding. I want to end with a progressive thought. Vietnamese football is in a transformation phase. Clubs invest more, players are more professional, fans are more knowledgeable. In that context, refereeing cannot stand still. VAR is an opportunity, not a solution. It is an opportunity for Vietnamese football to build a more transparent system, a firmer legal culture, and a more trusting relationship with fans. But opportunity does not become result on its own. It needs action. It needs those sitting in the VAR cabin to understand they are not merely deciding a match but setting a precedent for the future. It needs those in the media to understand they are not merely reporting but educating. And it needs fans to understand that referees are human too, and error is part of football. Same situation, two ways to blow the whistle — the law is never ambiguous, only the person holding the whistle is. But the person holding the whistle can be better trained, better supported, and treated more fairly. That is the road Vietnamese football should take. And I, as someone who records matches through a data-obsessed eye, will keep watching every step along that road.
