When the Archive Falls Silent: Data Gaps and Memory in Vietnamese Football

In the summer of 2026, when the domestic football season was suspended because of the pandemic, I hauled home fourteen tapes of National Cup finals, stretching from 2026 to 2026. The original purpose was simple: I wanted to recount something nobody remembers clearly — how many times Vietnamese teams equalised in the last fifteen minutes.

The first tape opened with wind screaming into the microphone. The camera was placed in stand B, low angle, no scoreboard graphics, no player names running across the screen. I rewound and rewound, trying to pin down the fifteenth minute of the second half, and realised I had no way of being certain. The team sheet the organisers handed to the press that year listed eleven names and then simply stopped. The line below — where the substitutes should have been — was empty.

I sat for a long time in front of that blank line. Not out of regret. It was because I suddenly understood something: what I was holding was not a document, but a document that had been gutted.

Across the twenty-two National Cup seasons I reviewed, only fourteen finals still existed on tape in my possession. The other eight survive as lines of results printed on paper, sometimes just a three-sentence item on an inside page. For a documentary filmmaker, that is an occupational paradox: I have enough scores to build a statistical table, but not enough images to tell a story. And the story is what I need.

Two decades of Vietnamese football written in spoken word

Vietnam's national championship began in 2026 under the name the A1 National Tournament. Twenty years later, the 2026 season marked the switch to a professional model, opening the V-League era — and according to the records still preserved, Song Lam Nghe An were the champions of that first professional season. The National Cup began in 2026.

The span between those milestones is territory where Vietnamese football data barely exists. No precise minutes played. No pass counts. No heat maps, no shot-distance metrics, none of what a modern analyst treats as the minimum condition for even beginning to talk about tactics.

That sounds like a loss. But after I spent nine months rewatching the entire old archive, I realised it is also something else: Vietnamese football back then was not short of information. It simply recorded that information in a different format — the spoken word.

When I first entered the trade in 2026, the newsroom's audio room had no computers. We had a typewriter, a thick notebook, and cassette tapes recording commentary sessions. Radio taught me that a voice can touch a fate, the way a foot touches a ball. If a commentator mispronounced a player's name, a listener in Hai Phong would catch it immediately, and the next day he would receive a letter. It was a crude, slow verification system, but it worked.

I still use those tapes today as a form of primary source. When three people give three versions of the same goal, I do not pick the version with more believers. I look for the point where the three accounts intersect, and treat that as the part solid enough to write. The poetics in that method lie not in embellishment, but in the fact that I am forced to trust people more than I trust numbers.

There was one final that took me nearly two months to reconstruct. I found three witnesses: a retired referee, an elderly supporter, and a forty-second radio recording. The three differed by as much as eleven minutes on when the opening goal was scored. The only thing all three remembered identically was the direction of the wind in the eastern stand. A detail useless to any spreadsheet, and the only thing that held.

What remains when the numbers vanish

In 2026, while shooting a short documentary about Hanoi FC, I captured the moment goalkeeper Nguyen Van Cong saved a penalty against Becamex Binh Duong. He dived to his right while his eyes stayed fixed to the left. No metric recorded that. No data model predicted it. There was only a cameraman standing in the right place, at the right second.

If I lost that tape, everything left would be the line "Hanoi 2-1 Becamex Binh Duong" and a note saying the goalkeeper was voted man of the match. The line is correct. But it contains nothing.

I have told young people in the trade many times that a goalkeeper is the poet of the penalty area, writing with the body instead of words. It sounds ornate, but it comes from a very technical observation: every movement of a goalkeeper is a sentence with grammar — the set, the read, the shift of weight, the change of mind. That grammar can only be read with the eye, not with a column of figures.

At Euro 2026, while making a short film about substitutes, I met Switzerland's forward Breel Embolo right after their round-of-16 match against France, which Switzerland won 5-4 on penalties. He came off the bench and equalised. I asked him what it felt like to touch the ball. He said: "I cannot remember the feeling of touching the ball, I only remember breathing like a hunted animal for twelve minutes."

Twelve minutes. That is everything statistics recorded about him in that match: twelve minutes, one goal. But his answer holds a layer of information no chart can reach.

A gap is not the enemy of data. A gap is evidence of what a football culture chose to record, and what it chose to forget.

When gaps are manufactured industrially

In recent years I have started watching a different phenomenon, and it worries me more than any lost tape.

It is the arrival of documents that look thoroughly complete but are hollow inside. A template with every heading in place: match name, date, venue, line-ups, events, conclusion. But each field holds a single abbreviation, a dash, or a sentence reading "insufficient information to assess". Headings complete. Content empty.

I call it the industrial gap, and I believe it is far more dangerous than a lost tape.

A lost tape incriminates itself. It is absent, and its absence is a clear message: something was here, and it is gone. The reader knows they are standing in front of a hole, and knows to be careful.

An empty template is different. It has the shape of a document. It has the layout of a document. It even has a table of contents, tables, subheadings. But it contains no event. If such a document enters an automated aggregation system, it becomes a data row with the same weight as any other — a row of "nothing" treated as a row of "something".

For someone whose trade is reading primary sources, this is the hardest kind of error to catch, because it does not create a gap. It creates a decorated gap.

The counter-intuitive point

The usual response to any data gap is to fill it. Digitise the entire old archive. Reconstruct every match report. Use models to infer what nobody recorded. That is the instinct of an age that believes everything can be measured, and that anything unmeasured is merely under-effort.

I think that instinct is half right.

The right half is preservation. Magnetic tape decays. Paper yellows. Storytellers die. With each passing year, some detail of Vietnamese football disappears forever, and no algorithm brings it back. Archival work is urgent work, and I spend most of my remaining time on it.

The other half is where I part company with the majority.

Not every gap should be filled. Some gaps should be kept open, and clearly marked as things we do not know. Because the only way to fill a gap is inference, and inference, in the field of primary sources, is a polite name for fabrication.

One very concrete example. None of us has ever seen the contract behind most transfers in Vietnamese football. The figure reported for a signing usually originates from an unnamed source, is then quoted elsewhere, then gradually hardens into obvious truth, until a player is valued at a number nobody can verify. In this case we do not lack data. We lack sourcing, yet we are full of numbers.

Another example, closer to my own work. In recent years, data on young players has been collected very early — in some cases from the age of twelve or thirteen. Height, weight, sprint speed, minutes played, goals scored. Those numbers are recorded before the body has matured, and they begin operating as an unerasable record. A fourteen-year-old who runs fast gets pushed into adult training rhythms. The data is full. But the right question — whether that body is ready — is the empty box.

In another direction, I have had occasion to watch a few esports competitions and talk to coaches there. It is the most perfectly data-rich environment I have ever seen: every click logged, every second replayable. And yet what I heard from the players themselves was a sense of being smoothed away. When everything is measurable, the unmeasurable gets coached out of existence. It turns out perfect data has its own kind of loss.

Based on my experience following matches across four decades, I see a fairly consistent rule: the most painful failures of Vietnamese football rarely come from a shortage of information, but from our being too confident in the information we have.

What should be taught to young writers

There is one sentence I always say in training sessions for young reporters: if you have no source, write that you have no source. That is not failure. That is discipline.

Our trade trains us to fill the page. From our school desks we learned that a blank space is a defect, that a good writer is someone who always has something to say. That produces a generation accustomed to writing first and verifying later — or not verifying at all.

But precisely because of that, the sentence "I do not know this" carries unusual weight. It is an event inside the piece itself. It marks the boundary between the territory with sources and the territory without, and it gives the reader the right to know where they are standing.

I began that discipline with my own tape archive. I built an index, and in that index there is a column reserved for what I cannot verify. That column is now nearly as long as the column of what I know for certain. I do not regard it as failure. I regard it as a map for whoever comes after.

Because I came late to football — I was fifty-two before I learned what a World Cup was, and I called it an obsession that needs no reason — I have never harboured the illusion that I know everything. The latecomer always has a strange advantage: he is not afraid to admit he is missing something.

What I want to leave behind

That summer of 2026 ended with a spreadsheet holding fourteen rows of data and eight empty rows. I once thought about deleting the eight empty rows to keep things tidy. Then I left them.

Because those eight rows turned out to be the part I reread most. They remind me that Vietnamese football has an incomplete record, and that this incompleteness does not make that history any less real. It only makes it harder, requiring more listening and more cross-checking.

The question I want to ask is not how many gaps we need to fill, but this: if we teach the next generation of writers that "no data yet" is a valid answer, what will the Vietnamese football archive look like twenty years from now?

And I want to close with thanks to the people who ran the cameras in 2026, who put the tripod in stand B because it was the cheapest spot, who wrote three sentences on a scrap of paper and kept it for twenty years. They did not know they were doing archival work. They were simply doing their job.

When the stadium is empty, I hear clearly the applause of the years gone by.
