The Empty Spreadsheet of Vietnamese Football

On the B stand at Hang Day Stadium, April rain swept across the pitch, and the man next to me opened his laptop in the twelfth minute. He works as an analyst for a V.League 1 club. His spreadsheet had fourteen columns: passes into the final third, ball recoveries within five seconds of losing possession, high-speed running distance, oriented pressing actions, broken first lines. By the ninetieth minute, eleven columns were still empty. Three cells had data: one assist, four shots, and a handwritten note in Vietnamese — "number 7 ran out of legs in the 70th minute."

When the referee blew the final whistle, he closed the laptop and said something I have carried for years: "We don't lack eyes. We lack paper."

A league without memory

V.League 1 has plenty of collective memory and almost no data. Fourteen clubs, hundreds of thousands of spectators each round, millions watching on television — yet if you want to verify something as simple as how aggressively a team pressed across its first ten matches, there is no consistent public source that can answer you.

For comparison: covering an Olympic cycle or a Tour de France stage gives me timing data accurate to hundredths of a second, average speeds per sector, heart-rate distribution, the number of accelerations on each climb. Covering V.League 1 gives me a scoreline, a scorer list, cards, minutes, and a three-minute highlight reel.

The consequence is that every professional argument slides toward sentiment, and sentiment belongs to whoever speaks loudest. A coach accused of having "no game plan" cannot rebut with numbers, because the numbers do not exist. A player labelled a poor mover cannot prove he covered more ground than anyone in his team, because his ground coverage has never been measured.

Information vacuums are never neutral. They always favour whoever controls the narrative.

Three layers Vietnam has never had

The first is event data — who passed to whom, where, when. Cheapest and easiest. Several Vietnamese clubs already do this, but in isolation: each records to its own standard, for its own purpose, and shares nothing. The league ends up with fourteen disconnected datasets, none of which can be joined to another. Cross-club comparison — the very thing that determines a player's market value — becomes impossible.

The second is positional data — where players stand, how they move, at what speed, across ninety minutes. This requires optical tracking or wearable sensors plus serious computing power. Vietnamese clubs do use GPS vests in training, which is a genuine start. But training data and match data are different worlds. A vest measures how far a player ran in a drill the coach designed. It cannot measure how he chose the wrong position during a counter-attack in the 88th minute.

The third is contextual data — who he played alongside, under what pressure, in what condition, against what opponent, in a match that meant what to his club. This is the most expensive layer and the most ignored, because it cannot be bought. It requires the time of people who understand Vietnamese football deeply enough to translate numbers into meaning.

You cannot skip layers. Vietnam can buy cameras. Vietnam cannot buy context.

The price of a three-minute highlight

Transfer decisions in Vietnam are typically made from three sources: a highlight clip, an agent's recommendation, and a decision-maker's personal impression from one or two live viewings. All three measure potential. None measures fit.

A three-minute highlight is assembled from a whole season. It contains a player's best moments in matches his team was winning. It does not contain the times he hid from the ball while his team was losing, the times he stood in the wrong place and tore open his own midfield, the way he reacted when substituted in the 60th minute.

Before becoming a name, everyone is only a stride.

In 2026 in Manchester I interviewed a seventeen-year-old after he scored one and assisted two in a youth cup final. Thirty-four minutes of conversation; he spoke twelve sentences, mostly about the team bus home. My editors wanted the "promising young star" angle and asked me to cut every trace of his awkwardness. I refused, and lost the commission.

A seventeen-year-old who speaks twelve sentences in thirty-four minutes is not necessarily a failure. He may simply be frightened. But to know that, you need a record of the person — something no highlight reel provides and no metric currently captures.

Dressing-room chemistry is data — we just refuse to record it

Here is my position, plainly: transfer valuation models systematically overprice young potential and systematically underprice dressing-room chemistry.

Potential is measurable — age, goals, minutes, touches. Chemistry is not, partly because it is hard, partly because measuring it forces people to say delicate things about their colleagues.

Picture a V.League club losing a thirty-three-year-old who started eleven matches all season. Statistically invisible. He was also the only person who spoke English with the naturalised striker at meals, the one who pulled young players apart during arguments, the one the coach called at eleven at night before a derby. When he leaves, no metric drops. Only results drop, from round nine onward, and nobody can explain why.

I saw the same thing while making the short-film project "The Empty Seats" in 2026, when global sport stopped. A cleaner who had worked at Old Trafford for twenty years told me that at night, with no match on, he still heard the roar echoing back off the empty rows. I wrote that sentence down. Had I only recorded attendance figures for that season, his voice would have vanished from the record.

The empty seats.

An empty seat still holds a person — we have simply stopped hearing their applause.

That is the most precise definition of the data Vietnamese football is missing. Not data about the people who shone. Data about the people who were absent, who were quiet, whose value lies precisely in leaving no trace on a spreadsheet.

The national team: where data is replaced by collective emotion

Vietnam's national teams consistently outperform the club game's standing, and much of that comes from a resource no spreadsheet measures.

The gap between national-team level and club level in Vietnam is not only a gap in quality. It is a gap in emotional density. A national team assembles for three weeks, plays four matches, two of which the whole country watches, and generates a level of cohesion a club playing thirty rounds cannot reproduce. That is an advantage, and it is also a trap: it makes us overrate short tournaments and underrate long seasons.

When Vietnam won the 2026 AFF Cup against Malaysia 3-2 on aggregate, when they won the 2026 ASEAN Championship in Bangkok on 5 January 2026 by 5-3 on aggregate, the emotion was exactly what it should have been. But behind those nights sits a question rarely asked: how much of that success is reproducible at club level — and how would we know, without data to compare the two levels?

I do not believe data can manufacture a Xuan Son, a Quang Hai or a Hoang Duc. I do believe data could answer a question we currently answer only with intuition: why does a player who excels at club level disappear in a red shirt — and why does an ordinary club player suddenly shine in one?

Right now, our only answer is "spirit". That answer is not wrong. It is also the answer that ends every further question.

Copying the European stack is not the answer

My contrarian view after years watching both European and Vietnamese football: if Vietnamese football imports the European data stack wholesale, it will gain a great many numbers and considerably less understanding.

Metrics do not exist independently of playing styles. Expected goals was built to assess chance quality in a league of organised low blocks, limited space and few chances per match. Apply it unchanged to a league with different tempo, different pitch quality, different fixture density and a far greater spread of quality between teams, and you get figures that look professional while pointing toward the wrong conclusion.

Worse, an imported system without translators creates a new risk: false confidence. Decision-makers feel evidenced when they are merely reading a table computed from assumptions that do not belong to Vietnamese football.

On the track, records are measured in hundredths of a second; outside it, lives are measured in breaths.

What V.League 1 needs first is not optical cameras. It needs agreement on one shared, league-wide set of definitions — simple enough that every club can record it, standardised enough that it can be joined into a single picture. A crude but consistent dataset is worth more than fourteen rich datasets nobody else can read.

And alongside it, Vietnam needs to record the things nobody calls data: who stood up first in the dressing room after a defeat, who stayed on the pitch forty minutes after training, who the youth team called "anh", who left without anyone noticing until the results collapsed.

On transfers, and the things we misname

A transfer is what we call a separation so that it sounds less like a separation.

Vietnamese academies — Hoang Anh Gia Lai with its celebrated generation, PVF, Viettel, Nutifood — have clearly improved over the past decade. What they have not done is measure that improvement in a way that converts into value. When a young Vietnamese player goes abroad, the buying club's first question is how many V.League 1 matches he has played. That is a question about quantity, not quality. Nobody asks at which position, in which system, against which opponents, under what expectations.

The result is an export model built on impressions. A player who performs in a short tournament — a SEA Games, an AFF Cup, one big match — attracts more attention than one who performs consistently across twenty-six league rounds. The market is not wrong to behave this way. It is responding to the only information it has.

What we choose to record

A good match is never fully told; it only waits for someone quiet enough to hear it.

The biggest risk for a football nation without data is not playing badly. It is never knowing where it went wrong. A coach sacked on someone else's intuition carries that intuition to his next job, and the cycle repeats while nobody learns anything.

The man on the B stand that rainy night in Hanoi is thirty-nine. He knows what Vietnamese football lacks, and he knows he cannot change it alone. He still comes to the ground every round, still fills three of fourteen columns, still writes his notes in Vietnamese in the margin.

That may be the most accurate image of Vietnamese football in this period: its most careful record-keepers working on pages nobody will read.

The question I want to leave is not when Vietnam will buy the cameras. It is this: if this season ends and those eleven columns are still empty, what will we use to know we lived through a year of football — the memory of whoever shouted loudest, or the truth of the match?
