Thirty-Nine Empty Files: Vietnamese Football and the Void Nobody Records
Shanghai, late September. The air conditioner rattled like a midfielder who ran out of battery in the seventieth minute. I opened a folder called VLeague_2024. Inside were forty-two data files. Thirty-nine were empty.
Two weeks earlier I had already imagined the entire article: an analysis of how V.League teams defend the final thirty minutes, built from a full season of event data, cross-referenced with substitution minutes, foul rates, and whether a side deliberately dropped its block or simply ran out of air. I had imagined the headline, the opening line, even the closing paragraph.
Then I clicked the first file. All that appeared was a cursor blinking in the top-left corner, steady and patient, like a referee waiting for a player to get back on his feet.
Thirty-nine out of forty-two.
I sat there a long while, not out of shock. I had expected this, to some degree. I sat there because I recognized the position this job puts you in every time you begin: facing a void, pen in hand, with an invisible pressure to fill it with something.
That void had a specific shape. It was forty-two matches I had watched, annotated, sketched into pencil formations on the margins of paper. It was also forty-two matches of which the official record preserved exactly three things: the scoreline, the scorers, their minutes.
Three things. Across ninety minutes.
I once thought this was a V.League problem. Then I remembered another afternoon.
In May 2026 I watched the Bundesliga's first restart match of the pandemic. No one in the stands. No drums, no scarves, no chanting. Only boots striking grass, and a coach berating his players through a pitchside microphone so clearly that I heard an entire German sentence whose meaning I did not know.
That night I wrote in my notebook: An empty stadium is an audition for the truth. When the noise disappears, what remains is not cleaner football but barer football — and barer football is usually uglier.
Same void. Different alibi.
I then spent three weeks manually tabulating eighty-one matches from the final nine Bundesliga rounds. The result kept me awake: home win rate fell from roughly forty-three percent to roughly twenty-one percent. I wrote a piece titled "A House Is Only an Idea," arguing that crowd noise is not decorative background — it is a twelfth player existing in physical form, acting on heart rate, reaction time, the split-second decision to release a pass.
Forty-three percent is a scream; twenty-one percent is a whisper of truth. I still believe that. But it took me years to understand its second half: to hear the whisper, you need a recording device. Where no device exists, you only hear the scream.
Vietnamese football sits on the scream side.
The V.League has fourteen clubs. Every matchday is a dense weekend of streaming, with hundreds of thousands of views for marquee fixtures. Yet if you want to know how many metres a right-back covered, where he received the ball, which zone he was beaten in — there is almost no official source to consult.
What you have: scorelines, scorer lists, cards, and a possession figure usually recorded by human eye. Which means it depends on what the recorder decided counted as "possession." In leagues with multi-camera tracking and machine-learning models, that definition is rewritten every season, documented, versioned. Here, it is an oral tradition.
I am not saying this to disparage. I am saying it because it determines which kinds of articles can exist.
When positional data does not exist, the writer retreats to three things still available: memory, imagery, testimony. Memory is biased. Imagery is fragmentary. Testimony depends on the witness. And Vietnamese football has been built, largely, on an oral architecture — where collective memory outweighs the number, and where a moment repeated often enough becomes fact by default.
I grew up inside that architecture.
At sixteen I was a trainee at a youth academy in Shanghai. In April 2026 I tore my ACL in training. The doctor was brief: the playing career was over. I did not cry, as I recall. I sat in the medical room, looked at the fixture sheet pinned to the wall, and thought something strange: that from now on I would never know what a misplaced pass at the centre of the pitch actually feels like.
Injury sent me to the touchline, where words became my legs.
On 26 November that year I sat in the stands at Hongkou Stadium for the second leg of the Chinese FA Cup final. My old club drew 3-3 and won on away goals. I went home and wrote two thousand words titled "Away Is Where You Learn to Come Home," using the away-goals rule as a metaphor for how injury forces you off the pitch in order to understand the pitch. Within three days it reached ten thousand reads.
That was the first time I understood something about this trade: the scoreline is only the skin; the story inside is the flesh. Since then, every piece I write opens with a moment, an image — never a scoresheet.
But from that same point, I began to distrust myself.
July 2026, the World Cup in Russia. I was seventeen, invited to commentate at a group viewing in Shanghai. Round of sixteen, Croatia against Denmark. In the first half I mispronounced the name Luka Modrić three times.
Some names must be mispronounced three times before they belong to you.
For the next month I rewatched all seven Croatia matches, handwriting fifteen thousand words on their passing triangles and on how Modrić found space between the lines. I discovered he missed a penalty in the 116th minute — then stood up, scored the first penalty of the shootout, and dragged his team into the final.
But what I remember most from that summer comes from a different match, in a different city.
In January of that year, in Changzhou, Vietnam's under-23 side reached the final of the AFC U-23 Championship. I watched on an unstable stream in a dormitory. Snow fell heavily on the pitch. Vietnam lost 1-2 to Uzbekistan after extra time. A free kick from Nguyễn Quang Hải had found the net in the second half.
That night an entire Vietnamese generation sat before screens and wept. I wept too, though only through a stream.
But here is what I want to say, and it is not easy to hear: for years afterwards, reading back through analyses of that tournament, I realized almost nobody could cite a single concrete tactical number. Nobody could say where Vietnam pressed, at what frequency, for how many minutes. All that survives is emotion — beautiful, powerful, but emotion.
That is not wrong in itself. But it produces a consequence: when collective memory replaces data, a tournament freezes into an icon. And an icon cannot be analysed, only worshipped or betrayed.
A nearer, less discussed example. The 2026 V.League season was cancelled mid-campaign because of the pandemic, after more than a dozen rounds, and that season has no champion. Emotionally, it is a blank year. In data terms, it is a year erased entirely — over a hundred matches were played, watched, contested, and left behind almost no retrievable technical record.
We lost a season. We also lost the ability to learn from it.
There is a technical reason this void exists, and another reason more rarely spoken.
The technical reason: positional data requires multi-angle cameras, computing infrastructure, trained operators, and contracts with international providers whose prices are not small against V.League club budgets. For a club whose win bonus barely covers a domestic flight, buying a premium data package is an investment hard to justify to a board.
The second reason: live data piped to betting companies is the darkest by-product of sport's digitisation.

Consider it this way. A positional feed updating by the second, with near-zero latency, does more than help a coach adjust his shape. It grants the betting market an asymmetry over television viewers, who see where the ball goes but not where all eighteen players stand at once. The value of such a feed to a bookmaker does not lie in helping a team play better. It lies in being sold to the highest bidder — and the highest bidder is rarely the club.
So sometimes, a football nation without deep data is not merely a poor football nation. It may also be one that has not yet been priced by the second.
I am not romanticising scarcity. I am only saying every void has two faces: it blocks analysis, and it blocks extraction.
Which brings me back to my folder of thirty-nine empty files, from a different posture.
When I started writing, I believed more data meant closer to truth. I believed it was a straight road. I learned Python after writing about empty stadiums, abandoning coursework, convinced I was building something. A few years later I saw that belief had a blind spot.
The blind spot is this. A data void is not simply "we do not know." It is a funnel, and inside that funnel, what gets poured in is always what is easiest to pour, not what is most accurate. Story. Character. Tragedy. A snowy night in Changzhou and a nineteen-year-old's free kick.
All of it is real. But it fills the space where the number should stand, and once installed there it becomes untouchable — you cannot argue against a memory. You can only betray it.
The tactical machine always has a screw called the human being. The reverse is also true: every human story conceals a screw nobody bothers to turn.
It is transfer window now, and I am watching that same funnel operate at higher frequency.
The transfer window — a festival of promises with expiry dates.
Every summer, Vietnamese football coverage talks endlessly about money. Almost nobody talks about structure. A contract is not just a transfer fee. It has a duration, a signing bonus, a release clause, a sell-on percentage for the previous club, appearance bonuses, goal bonuses, continental qualification bonuses. Those terms decide which clubs are genuinely rich and which merely look rich.
But to write about structure, a writer needs contract data — and contract data in the V.League is, once again, more often transmitted by word of mouth than stored.
So the public receives what is easiest to receive: big numbers. And when only big numbers exist, fans begin to judge players by price and clubs by budget, forgetting the more important question — which structure makes a player better in one environment and worse in another.
That is another kind of loss. Not the loss of a match, but the loss of the ability to understand why a match unfolded as it did.
I once assumed technology would fill this void. When VAR arrived in the V.League, I waited eagerly. But VAR does not create open data. It only creates another closed room, with another screen, and another group of people making decisions. It makes argument more precise without making understanding more widespread.
That is a lesson my own trade taught me: better tools do not automatically generate better knowledge. They generate higher-quality disputes.
There was a time I had to pronounce Vietnamese players' names for an editor in China. I got them wrong three times. He corrected me patiently. On the fourth attempt he said something I have carried since: "If you cannot say the name, you cannot write about the person."

I think that is true at a level deeper than language. If you cannot measure it, you cannot analyse it. And if you cannot analyse it, people will tell stories instead of understanding.
That night, after shutting the laptop, I did not sleep. I reopened a V.League match I had watched at the start of the season, muted the commentary, and timed it myself. I counted how often a team played long when pressed. I counted the seconds from winning the ball to the first shot. I did that across four matches, over four nights, by hand, in a notebook, exactly as I once did with the Bundesliga.
Four matches is not data. Four matches is a splinter.
But a splinter still beats a total void.
The pitch never forgets, but it forgives. People are different. People forget quickly, then forgive themselves for forgetting by calling it tradition.
If there is one thing the generation writing about Vietnamese football should do in the coming years, it is not to wait for a European-grade data system to appear. It is to start recording what we see, systematically, even if it is one person and one notebook. Count substitution minutes. Note player positions when the team loses the ball. Mark the seventy-fifth minute of every match and see how often the block drops.
It sounds small. But every football database in the world once began with a person in the stands holding a sheet of paper.

Perhaps in ten years, people will look back on this phase of Vietnamese football as one remembered more through emotion than through numbers. That is not bad. But it poses a choice for those writing today: either remain the reteller of memory, or begin to become the archivist.
I do not yet know which group I belong to. But I know I do not want to open a data folder ten years from now and see the cursor blinking again.
