The Blank Spreadsheet: Vietnamese Football Is Analysing Itself by Eye

The Blank Spreadsheet: Vietnamese Football Is Analysing Itself by Eye

Busan, two in the morning.

The café on the slope near the port closed hours ago, leaving me with a laptop and a cold cup of coffee. On the screen, a V.League match streams through a website cluttered with flashing adverts. Beside it sits a spreadsheet with four columns already open: PPDA — the passes a team allows its opponent before every defensive action; passes into the final third; aerial duel success rate; and shots taken within thirty metres of goal after a turnover.

I sat through ninety minutes plus stoppage time. When the final whistle went, all four columns were still blank.

I was not being lazy, and the match was not bad. The point is that once the referee blew up, there was no public source against which I could check what I had just watched with my own eyes. No pass map, no pressing numbers, no positional data by phase. Only the scoreline, a few possession figures rounded to the nearest ten, and match reports typed while the ball was still rolling.

I started writing about football in 2026 at the Newark Advertiser, when a fax machine still counted as impressive technology. Thirty-three years later I write about Korean football with two monitors and a data dashboard open beside me. I have never felt as though I were analysing a match with my eyes shut as I did that night.

Four blank columns. That is the gravest problem in Vietnamese football right now, and almost nobody outside Vietnam will say it out loud.

Results have outrun the infrastructure

Vietnamese football has had a genuine decade of achievement, and it needs no embellishment. In 2026 the under-23 side reached the final of the AFC U-23 Championship in Changzhou, losing to Uzbekistan only in extra time. Later that year the senior team won the AFF Cup over two legs against Malaysia. In 2026 Vietnam reached the third round of Asian qualifying for the World Cup for the first time, sharing a group with Japan, Australia, Saudi Arabia, China and Oman. In early 2026, under the Korean coach Kim Sang-sik, Vietnam beat Thailand 5-3 on aggregate to win the ASEAN Championship. That list is enough to make any other Southeast Asian nation envious.

Domestically, V.League 1 runs with fourteen clubs and twenty-six rounds, plus the National Cup and play-offs. V.League 2 has twelve teams and a calendar that stretches across most of the year. In 2026-24, Thép Xanh Nam Định won the top flight, the club's first title in nearly four decades. In terms of results, this is a living, breathing system that produces stories international media occasionally picks up.

But the information layer of the league has not travelled with the results layer.

I live in Busan and often go to Gudeok Stadium to watch the local side in Korea's second tier. After every match there, even a second-division game nobody broadcasts beyond the border, I can open my laptop and pull up passes by zone, pressures applied, distance covered, duels won, broken down per player. All of it free, all of it public, all of it downloadable.

That is the gap this piece is about. Not a gap in player talent, and not a gap in money. A gap in the ability to observe itself.

Where the void comes from, and why it persists

No international data provider holds a detailed collection contract for V.League 1. That is not rumour; it is the state of affairs anyone who has tried to look up league metrics already knows. To produce data you need people logging every event in real time, or you need multi-angle cameras synchronised and processed by recognition software. Both routes cost money, and both demand a certain level of organisation.

Market logic is simple: data providers only invest where somebody is willing to pay to use the data. In Europe, the payers are clubs that want to scout, betting companies, broadcasters and the league itself. In Vietnam that chain does not close. Clubs do not pay because budgets are thin. The league does not pay because it is not a line item in the annual plan. Broadcasters do not pay because data does not hold a general audience. So nobody pays.

Club licensing rules set by the federation and by Asian confederation bodies are fairly explicit about facilities, about academy structures by age group, about financial reporting. Those requirements matter, but none of them covers publishing match data. A club can meet every condition for continental competition and still fail to produce a single pass map for its supporters after a game.

The first consequence lands on the craft of writing itself. Without data, a writer is pushed towards two substitutes: emotion and narrative. Emotion sells, narrative sells, but neither can be queried afterwards. If I write that a holding midfielder commanded the middle third well, I can write that sentence ten times a season and nobody can check it, including me. Analysis becomes commentary, and commentary does not accumulate knowledge.

The second consequence is heavier, and it lands on the players.

Invisible players and a one-way transfer market

I have followed the moves that took Vietnamese players abroad for more than a decade. Nguyễn Công Phượng joined Incheon United in K League 1 in 2026, then had a spell at Sint-Truiden in Belgium. Lương Xuân Trường wore the Gangwon FC shirt in K League 1 in 2026. Đoàn Văn Hậu signed for SC Heerenveen in the Netherlands in 2026. Nguyễn Quang Hải joined Pau FC in France's Ligue 2 in 2026. Nguyễn Văn Toàn moved to Seoul E-Land in K League 2 in 2026.

What almost every name on that list shares is a shortage of minutes. Văn Hậu never made a competitive first-team appearance for Heerenveen. Công Phượng's starts in Korea can be counted on one hand. Quang Hải made fewer than twenty Ligue 2 appearances, mostly from the bench, before returning home. Văn Toàn left a modest mark in Korea's second tier and also came back.

The question usually asked is whether Vietnamese players are good enough. I think that is the wrong question, or at least a question asked far too late. The right question comes one step earlier: how is a Japanese or Korean club supposed to know whether a Vietnamese player fits its system, when the only file it holds is a three-minute highlight reel online and a handful of national-team games?

Scouting in Japan and Korea follows a fairly fixed order. The analytics department scans a large pool of players against the metrics that suit the team's model. From that pool they build a shortlist, then watch video, then send someone to watch in person. Vietnamese players are eliminated at the first step — not because they play badly, but because they do not exist in any database.

Some stars only burn brightly where they are loved, not where the lights are brightest.

Nguyễn Công Phượng at HAGL was a phenomenon who packed the stands in Pleiku, and what he produced inside that system was far from trivial. Abroad, he became a blurry variable inside a system not built for him. The difference was not technical quality. The difference was whether anyone understood where on the pitch he belonged.

The reverse flow suffers the same disease. Every transfer window, V.League witnesses a fresh churn of foreign players: strikers from Brazil, Nigeria, Korea, Jamaica who arrive and leave within months. Many of them are signed on the strength of a clip and a phone call from an agent. There is no data to test whether a striker who scored twenty goals in a third-tier African league can convert that into ten goals in V.League. Money gets burned, time gets burned, and so does the audience's faith.

The summer transfer window is a stage where people buy stars and sell patience. In a league without data, patience is sold off more cheaply than anything else.

Fixture density, injuries, and decisions made on feeling

Throughout my writing career I have held a rather stubborn belief: fixture density is the number one cause of injury, and no medical department can save a player asked to play twice a week for months on end.

Vietnam's calendar has a peculiarity I have not seen in many places: it swings violently between two extremes, and both are harmful. In 2026, V.League halted mid-season after roughly twelve rounds because of the pandemic, and the season was cancelled. In 2026, the competition had to catch up with long breaks ceded to regional tournaments and the national team, then crammed fixtures into short windows. Vietnamese players live inside a cycle their bodies are never prepared for.

In 2026, when global football stopped, I wrote a piece with a rather extreme headline: Cancel the season. I argued that a title won with no spectators in the stands was meaningless. Months later, when Liverpool were confirmed champions with nobody outside the stadium, I felt hollow and began to doubt myself. I deleted the post. More than a hundred days without football taught me that my emotions are not a measure of truth, and since then I write more slowly.

I bring that up for a very specific reason. My error in 2026 was issuing an absolute verdict while short of facts. That is precisely what Vietnamese football is doing to its players' bodies.

Without load data — without distance covered, without sprint counts, without acceleration records — the decision to bring a player back from injury becomes a negotiation between the player's sensations, the coach's pressure and the board's needs. Đoàn Văn Hậu is a painful example. After returning from the Netherlands, he suffered repeated muscle injuries, and each comeback seemed rushed. I lack the evidence to claim that a serious load-monitoring system would have saved his career, but I am fairly sure it would have forced the right questions at the right moments.

As far as I understand it, most V.League clubs do not use GPS tracking with their players in any systematic way, and where equipment exists, the data is rarely archived across a season for comparison. An injury that is not recorded cannot be learned from, and a football culture that cannot learn from injuries will repeat them on something close to a schedule.

Youth development and a forgotten talent pipeline

Vietnamese football has every right to be proud of its academies. The HAGL academy, run on the JMG model in partnership with Arsenal, opened in 2026 and produced the generation behind the Changzhou miracle. The PVF centre opened in 2026. Viettel, SHB Đà Nẵng, NutiFood and others run genuinely serious programmes.

But that system is bleeding in a place few people watch.

When a graduate moves abroad, international transfer rules include training compensation and a solidarity mechanism, calculated on the years a player spent at each club between the ages of twelve and twenty-three. The mechanism exists so that the places which raised a player recover some of the value they created.

In Vietnam, that mechanism is rarely pursued to its conclusion. A provincial club invests seven to ten years in a player — feeding him, schooling him, training him — then watches him leave for a settlement that will not cover the electricity bill at the training ground. The incentive to invest in youth erodes from within, and clubs take the short route: buy a proven foreign striker who can start on Saturday.

I once wrote that satellite club systems help wealthy clubs sidestep domestic training rules and turn small-league prodigies into satellite assets. Southeast Asia has a quieter version of the same mechanism. Big, rich clubs recruit thirteen- and fourteen-year-olds from the provinces for very small fees, absorb them into their systems and capture all future value. The small club becomes a raw-material supplier with no equity in the finished product.

Add the pressure of foreign player quotas, which hover around three matchday slots and shift from season to season. When the attacking places are usually occupied by short-term foreign signings, the path forward for a nineteen-year-old Vietnamese striker narrows sharply. And because there is no data to prove that the youngster is developing faster than the import, that contest always ends the same way.

Where I could be wrong

The consensus on Vietnamese football, at home and abroad, revolves around three things: more money, more facilities, and another good foreign coach. I do not oppose any of that. I simply think it does not reach the root.

My contrarian claim is this: the biggest problem in Vietnamese football is not a shortage of money, but the absence of any way to know where the money goes and what it buys. Pumping cash into a market that cannot measure player value only inflates fees and wages; it does not automatically improve the product. A league that cannot see itself cannot fix itself.

There is a stronger and more contestable version of the argument: the greatest obstacle for Vietnamese players abroad is not physique and not technique, but invisibility. Clubs in Japan and Korea are not short of goodwill towards Southeast Asian football. They are short of a filter. Without data, the only route for a Vietnamese player into a J.League club's view is a personal recommendation. That means only the most famous get the chance, and famous is not the same as suited.

But I must be honest about where I might be wrong.

Korean football in the 1990s was desperately short of data and still produced continental-class generations; the data arrived later. Perhaps the correct order is: first a seriously governed league with crowds and broadcast revenue, and data follows. It is also possible that Vietnamese clubs already hold datasets internally that I, a foreigner in Busan watching through an unstable stream, cannot access. I cannot be sure I see the whole picture. All I can see is the tip of the iceberg, and the tip is blank.

I write against the wind, but my heart is never against football.

A verifiable prediction

I will make one checkable prediction, and I am ready to be wrong.

If within the next three seasons the professional league body or the federation adds the publication of detailed match data to its club licensing criteria, or if a regional data provider signs a contract with the top flight, then within two transfer windows at least one Vietnamese player will move abroad on the strength of a complete data profile rather than a highlight reel, and the average fee for moves to J.League 2, K League 2 and the Thai League will rise noticeably.

If by 2029 no such data contract exists, my argument has failed, and I will write the retraction myself.

I do not write to be agreed with. I write to wake a question that has fallen asleep: can a football nation win Southeast Asia and still have no way of seeing itself — and if so, is it moving forward, or simply running faster around the same old circle?
