The stands of Hoa Xuan were so empty that I could hear the ball sigh.

In the summer of 2026 I lost my way inside a sports complex in Da Nang and sat down in the wrong block, Block B, for the U19 match between SHB Da Nang and U19 Ha Noi. The first half was so dull that I stood up to leave. Then, in the 73rd minute, a player wearing number 10, Dang Van Toi, took the ball with the outside of his right foot. The ball drew a curve shaped like the letter S before it struck the post. I did not know who he was. I only knew my heart was beating fast, the way it does when I hear a strange poem.
After the final whistle I did what any writer would do. I went looking for data. I wanted to know how many times the boy had touched the ball, how far he had run, how many chances he had created. I wanted a number to place beside my own feeling.
There was nothing.
The organisers had a team sheet printed on A4 paper. The scoreboard had the score. That was all. I sat alone in Block B, opened my notebook, and wrote exactly three lines: the score, the name of the number 10, and a question.
Nine years later, at 67, I still write about Vietnamese football with that notebook. It is much thicker now. But the empty columns are still empty.
What we keep when a matchweek is gone
Every weekend, fourteen clubs in V.League 1 walk out onto the pitch. Ninety minutes, hundreds of touches, thousands of small decisions, each lasting a few hundredths of a second. When the final whistle blows, what remains is usually this: the score, the scorers, and a few cards.
Open a European match analysis page and you will find a forest of data. Possession. Passes. Pass accuracy. Expected goals. Expected assists. PPDA. Recoveries in the opponent's final third. Heat maps for every individual. Distance covered split by speed thresholds. Those things exist because there are tracking cameras, collection companies, and buyers.
In Vietnam, most of that does not exist publicly.
Based on my experience watching matches — eight World Cups, eight Olympic Games, and more than two decades in the stands of domestic stadiums — I can state one thing clearly: the gap does not come from a lack of eyes. We have eyes. We lack people who write things down.
There is a story I have never told in full. In 2026, during a World Cup quarter-final on television, I described a pass from Luka Modric as the low note of a cello inside a choir of falling snow. The internet turned me into a poet who had wandered onto a pitch. A week later, when the match went to extra time, I stayed silent for seven seconds and then said one sentence about the Russian winter. The head of the sports channel called me and told me to keep doing exactly that: the audience hates it and keeps watching. Being called poetic on television is something I am proud of — the ball is poetry. But I also learned something else that night: an image only stands up when a fact lies beneath it.
And in Vietnamese football, the most trustworthy fact usually sits inside an empty field.
I should add something about the scouting profession. What does a Vietnamese scout work with? With his eyes, his memory, and phone calls. He watches a match, notices a small player who controls the ball with one touch and passes, and files a ranking inside his head. Nobody can check that ranking. Nobody can challenge it. Nobody can preserve it. And when he changes jobs, the ranking disappears with him.
I have asked myself: if I had not sat in the wrong block in 2026, where would Dang Van Toi be now? I have no answer. But I know a football nation cannot run for long on wrong-seat accidents.
Six analytical columns and six empty fields
Anyone who writes about football must sooner or later answer six groups of questions. How does the team play. How does the team spend. What story do the results tell. Where does the team sit in the league map. How are the rules being applied. And what is happening inside the dressing room.
In every column, Vietnamese football leaves a field blank.
Tactics. You want to know how aggressively a team presses. The international metric for this is PPDA — the number of passes an opponent is allowed before being disrupted. When it falls, the team is pushing high, closing down, accepting risk. In V.League, that metric is not published. To know, you must count by hand.
So I counted by hand. One afternoon in a central Vietnamese stadium I sat with a sheet of squared paper and counted every pass the away side made in the first twenty minutes. Forty-seven passes. I concluded that the home side was not pressing at all; they were simply holding position and waiting for the ball to enter a safe zone. The conclusion was correct. But it cost me twenty minutes of a ninety-minute match, and it cost me the match itself, because I was busy counting.
There is another, less discussed consequence. A coach who wants to correct his own team must review the game. In Vietnam the footage exists, but the footage is not tagged. Nobody records that in the 12th minute the team lost the ball here, that in the 34th minute the left-back was dragged three metres out of shape. To review it, a coach must scrub through ninety minutes by hand. Few have the patience. And so many lessons are left behind on the tape.
When a match is not measured, people judge it by whatever is most dazzling to the eye. A dribble past three defenders is more attractive than a sideways pass in the right place. A thunderous shot draws louder applause than a timely cover. I once watched an esports match and recognised the same disease there: the crowd roars at the brilliant teamfight, while the outcome is decided by map vision and the tempo control of the shot-caller. Without data, viewers cling to the explosion. With data, viewers begin to see the structure.
Money. How many V.League transfers disclose a fee? Very few. The familiar formula is that both parties decline to reveal it. That means we cannot know what a player is worth relative to others in his position, cannot know how far a club's wage bill exceeds its revenue, cannot know who is selling their own future cheaply.
But in this column I want to raise something else. The shirt is gradually becoming a mobile advertising hoarding. Global sponsor names cover the back, while the name of the village, the factory, the school that once stood behind the club fades. Global sponsors care about exposure, about screen time, about return on investment. They do not care whether a child in a coastal district ever gets to see his own team. When the community link is replaced by an exposure contract, the club survives but the root rots. And because nobody publishes the sponsor figures, we cannot even argue about it with evidence.
Results and public opinion. Here the gap produces a false diagnosis. A team that loses three in a row is immediately declared to be in crisis. But in those three matches, how many chances did they create, from where did the opponent shoot, how many saves did the opposing goalkeeper have to make? Nobody knows, because nobody measures. So instead of a technical diagnosis we receive a moral one: weak character, no hunger, lost spirit.
Public pressure, too, runs on feeling. A coach is told to resign after two matchweeks. A player is criticised for a miss that belongs to the hardest category of chances in the game. Without data, the loudest voice wins. And the winner of that argument never has to answer for being right.
The league map. In a healthy football system you can see the flow: which club develops and sells, which buys to compete, which buys to plug a hole. To see that flow you need transfer fees, ages, minutes played, contract lengths. Three of those four are never published. The only thing moving across the Vietnamese league map is names.
This sounds minor. It is not. A football nation that cannot see the flow of talent cannot tell whether it is getting stronger or hollowing out. It only knows whether it feels happy or sad.
Rules and governance. Refereeing controversy is the most visible part of Vietnamese football. A denied penalty generates more articles than a change to the competition format. Meanwhile, referee assistance technology has entered a portion of matches, and each time it appears, viewers demand an explanation. Demanding an explanation is reasonable. But to hear an explanation, someone must preserve the reasoning. We have decisions without records. We have verdicts without arguments. And without arguments, every dispute ends in personal belief rather than shared agreement.
The dressing room. Nobody gets in. When nobody gets in, people build characters. The veteran is a character. The difficult star is a character. Those characters live in newspaper pages far longer than whatever actually happened inside the room.
In this last column I want to stop at the position I believe is most misunderstood: the goalkeeper. The goalkeeper's ability with his feet has been sanctified to the point where it eclipses the most basic skill of the trade. A goalkeeper with good feet is mentioned every week, valued highly, treated as a tactical component. Meanwhile reflexes — the core of the job — decline with age and with minutes played, and that decline is almost never measured in Vietnam. Without a save-to-expected-goals figure, nobody notices that a goalkeeper has grown half a step slower. Feet are visible. Reflexes need data. And so a goalkeeper past his best can still fetch a peak-price fee, simply because he plays beautifully with his feet.
What we believe, and what I think is wrong
The common belief in the industry is simple. We lack data because we are poor, because the technology has not arrived, because the league is not yet professional. The accompanying solution is equally simple: buy a system.
I do not entirely believe that explanation.
The opacity here is a wall built on purpose, not a hole somebody forgot to fill. Undisclosed transfer fees protect clubs from comparison. Undisclosed wages protect the dressing room from resentment. Undisclosed data protects coaches from being questioned about process, and lets a defeat be explained by luck. Vietnamese journalism grew used to standing outside that wall, knocking, and then writing about the knocking.
The second problem is heavier. When we import metrics, we import a definition of beauty along with them. PPDA was designed for a football culture where teams press out of the same instinct. Expected-goal models are trained on European shot distributions. Bring them into a league with a different tempo, different pitches, different weather and a different culture of waiting, and you get a distorted picture. Worse, you get a picture that tells Vietnamese football what it is missing.
It is missing something real. But it is missing it in its own way, and what it is missing is not where people usually look.
What we lack, before data, is a small and cheap habit: writing things down.
I have been in this trade long enough to watch a generation pass. Quang Hai, Tien Linh, Hung Dung are names people will repeat for another twenty years. But the matches that produced them are fading from collective memory, because they were never recorded in enough detail to exist independently of memory. Everyone has a memory of an AFF Cup final at My Dinh Stadium on 15 December 2026. But the number of passes that broke the midfield line in that match, the number of times the opposing back line was pulled out of shape, exist in no public Vietnamese football database.
A goal is remembered through emotion. A season is remembered through goals. And so a season is remembered through very little.
Empty stands, but history still needs an audience to tell its most beautiful sadness. In Vietnam we have the audience, we have the sadness, we have the beauty. What we lack is someone to tell it honestly.
Where the notebook begins
I am not proposing that we buy a system. I am proposing that we buy a notebook.
Every club, after every match, writes three lines. What we saw. What we tried. What we lost. Those three lines require no algorithm, no tracking station, no billion-dong data contract. They require one person willing to sit for forty minutes after the whistle, when the floodlights are off and the players have boarded the bus.
From those three lines, after one season, you have a hundred and forty-four pages of league diary. After three seasons, you have an archive. After ten years, you have a history. And inside that history, some fields will no longer be blank.
Working as a sports journalist at 67, I have learned that a full notebook is less frightening than a blank one, because a blank notebook forces people to trust each other. I do not want Vietnamese football to have to trust itself that much.
The rough gem does not need polishing, only a gaze patient enough to love it. That gaze, if it is never written down, lives inside one person and dies with him. The boy did not need tactics; he needed someone who could read the hunger of ambition. But for that reader to write down what remains after the hunger, there must be room for the fact to stand.
In 2026 I wrote a piece about a boy drawing the letter S on a football pitch. It was read, and the boy was called up to the youth national team. I tell this not to boast. I tell it to say that a detail written down can change a life, and a detail forgotten can erase a life from history.
At 67 I still believe in magic, because I have seen a rough gem find itself in the mud. But I also know that magic is only believed when somebody tells it.
If you work in Vietnamese football, start today. Do not wait for the system. Do not wait for the data. Open the notebook. Write the first line. Because nine years from now, someone — perhaps another 67-year-old, perhaps a child not yet born — will sit down to look for your match. The only thing that will let them find you is the line you write tonight, when the lights have gone out.
