The Blank Pages of Vietnamese Football

The match ended at 9:47 p.m. The referee blew the whistle, the two sets of players shook hands, the stand emptied in long streams of people. In the fourth row of Stand B, a man folded his notebook, pushed it into his coat pocket and walked quietly down the stairs. For ninety minutes I had sat three rows away and watched him write four lines. At the stadium gate I asked what he had noted. He smiled: "The names of the young lads. The rest I keep in my head."

That night I went home with an uncomfortable question: if the only man willing to stay behind after a match writes four lines, what will be left of this league ten years from now?

Vietnamese football has a very rich memory but very thin records. That is the paradox I have watched for years in this job.

The past decade is the finest run of results in the history of Vietnamese football. On January 27, 2026, Vietnam's U23 side lost 2-1 after extra time to Uzbekistan in the AFC U23 Championship final in Changzhou, China, then came home into the arms of a nation. On December 15 of the same year, the senior team beat Malaysia 1-0 in the second leg of the AFF Cup final at My Dinh Stadium, closing out a Southeast Asian title after ten years of waiting. In 2026 and 2026, the U23s won SEA Games gold twice. In July 2026, the women's team played its first World Cup, in New Zealand. In early January 2026, the men's team won the ASEAN Cup, beating Thailand 5-3 on aggregate across the two-legged final.

The results are plentiful. But when I went looking for material on how those results were produced — which pressing drills, how the defensive block shifted, who first spotted a fifteen-year-old player — most of the answers sat in a handful of people's memories, not in any system.

The spell when Park Hang-seo coached the national team from 2026 to 2026 is the most discussed period. Yet the sources on his methods are mainly interviews, memoirs and press conferences. Very few internal technical documents were ever published, and there is almost no data set that allows Vietnam's defensive block to be compared across tournaments in numbers.

V.League 1 currently has 14 clubs. The budget gap between the leading group and the bottom group can reach dozens of times over. But what is more unequal than budgets is the capacity to write things down. The number of clubs employing a full-time data analyst can be counted on one hand. Most teams use an assistant coach who also cuts clips, counts passes and takes notes — usually close to midnight, after the match is over.

I do not need to travel far to see the contrast. In Thailand, Buriram United and BG Pathum United run their own analysis departments and hire foreign specialists. In Japan, every J.League club has a data unit independent of the coaching staff. In Vietnam, when a coach is sacked mid-season, his successor usually inherits a laptop with a few unnamed video folders. The handover file between two coaching regimes in the V.League is often emptier than a match with no written record.

Metrics such as xG (expected goals) or PPDA (passes allowed per defensive action) barely appear in the everyday language of Vietnamese football. International data platforms do cover the V.League, but at far lower granularity than the European leagues, and very few clubs buy that data back for analysis.

Vietnam's youth system is not weak. PVF, the Hoang Anh Gia Lai JMG Academy, Viettel and Nutifood have all produced good generations of players. The problem lies downstream: when an eighteen-year-old enters the V.League, he enters a market with no yardstick. Nobody values him through data, so people value him through gut feeling and connections.

There, the loan-with-obligation-to-buy mechanism works in the way most unfavourable to small clubs. A mid-tier club develops a player, loans him out, then is forced to sell once the clause triggers. Every contract is a promise, but football has never kept a promise. Small clubs keep raising semi-finished goods for big clubs, and what is called sustainable development is really a supply chain disguised in elegant language.

Above them, the Vietnam Football Federation manages the AFC Champions League slots and the club licensing system. The licensing criteria mention facilities, finances and youth development. But criteria on data and performance analysis are almost non-existent. A club can be licensed for Asian competition without proving it keeps any professional record at all.

This paradox is not unique to football. In Vietnamese esports, where many competitors retire at twenty-five, the post-career support system is close to zero. In the world of esports, people win without taking off their shirts to celebrate — and nobody records the way they won either.

The biggest blind spot in Vietnamese football's collective memory is that we remember the goals but forget the bodies. We know by heart the name of the man who scored in the 89th minute, but few recall who tended the grass in the penalty area all season so that the goal did not slip away. The groundskeeper of the national My Dinh stadium has never once watched a match from the VIP seats.

Based on my experience following matches, the first thing lost when nobody writes anything down is not tactics. What is lost is the body: the defender's shoulders sagging in the 70th minute, the midfielder's ragged breathing after three sprints in a row, the coach's knees buckling when the referee points to the penalty spot. Tactics can be rebuilt from memory. Bodies cannot.

I once stood beside a pitch caretaker on an afternoon with no spectators, when the whole country was under lockdown. He was still trimming the grass in the penalty area centimetre by centimetre. He said: "Grass doesn't know whether anyone is watching. Grass only knows it has to be green."

But I do not want to end on a lament. The oral memory of Vietnamese football holds a power that data does not: it carries emotion. When an old supporter tells his grandchild about the night at My Dinh, he does not pass on statistics. He passes on a vibration. There is a kind of football that happens after the stadium lights go out, and that football survives only in human memory.

The problem is that memory fades while records do not. A football nation that leans only on recall will forever depend on specific individuals — and when they leave, a whole layer of understanding leaves with them. Names like Nguyen Quang Hai, Nguyen Hoang Duc, Nguyen Tien Linh, Nguyen Xuan Son or Huynh Nhu will be spoken for decades. But the way they moved, the way they carried pain, the way they read a match is drifting away every day.

I sat beside an old supporter for ninety minutes. He did not sing, but he knew every name. When I asked him for the starting line-up of a match from twenty years ago, he recited it fluently. When I asked him where that team pressed, he fell silent.

The next step for Vietnamese football is probably not hiring another foreign expert or spending more on transfers. It lies in something much smaller: paying one person to stay behind after every match, open a notebook, and finish the page. Not for the archive. So that the next generation does not have to start again from zero.
