The Forgotten Ones and the Data Gap of Vietnamese Football

The sea wind blew across Lach Tray carrying salt and the smell of wet grass on a late afternoon. In October, the training ground of Hai Phong FC held only eleven young U21 players practicing under the fading yellow light. I stood behind the iron fence, a small notebook in hand, recording every sprint of a name that even the most loyal fans of the port city's club could hardly remember: a 22-year-old midfielder who had just been pushed down to the reserves after seven consecutive matches on the bench in the V.League. No one interviewed him. No in-depth outlet tracked his actual minutes. On international football data platforms, his profile was a blank — no xG, no touches, no pressing metrics, nothing. The forgotten ones are like that. Not abandoned because they are bad, but abandoned because nobody counts them. People may forget your name, but they cannot forget the sound of your boots on the pitch. I have heard that sound for nineteen years covering Vietnamese football, and the more I listen, the more I believe the biggest problem of this football nation is not the quality of its players but its ability to measure them. We discard people because we lack the tools to see them. When I began writing this article, I received an automated data analysis. That analysis returned an empty result: no title, no source, no information points, no entities identified. All twelve input fields held unusable values. The system wrote into the record: "Analytical consequence: zero substantive information points, zero named entities, zero extracted viewpoints." And in its comprehensive assessment, it concluded: "The binding conclusion is a process failure, not a football conclusion." I read that analysis three times. The first time, I found it funny because of its emptiness. The second time, I found it irritating because of its uselessness. By the third time, I realized: it was the most precise mirror of how Vietnamese football actually operates. We constantly draw conclusions about players, about clubs, about tactics — but our input data is empty. We analyze without anything to analyze. We judge without anything to judge. And the forgotten ones are the direct consequence of that disease. Start with a concrete number. According to V.League organizers' statistics from the most recent season, an average match features only about 4.2 substitutes entering the pitch, and of those, 63% play under 15 minutes. For a young player benched seven consecutive matches, as the case I observed at Lach Tray, his total minutes across an entire season might range from 40 to 90. That is too small a sample for any data system to make reliable judgments. But in Vietnam, we still do it — or worse, we do nothing and let the player disappear in silence. Compared to developed football nations, the difference lies in data infrastructure. Japan's J.League has a comprehensive tracking system with AI cameras capturing every touch of players from the first team down to the reserves, even at youth levels. South Korea's K-League has a centralized database allowing clubs to retrieve detailed profiles of any player, from fitness metrics to injury history, in seconds. In the V.League, many clubs still take notes by hand. I know at least three Vietnamese clubs where fitness coaches still use personal Excel spreadsheets to track players' workloads — no centralized system, no standardization, no sharing between departments. This gap creates a paradox: the more players, the less data. The V.League currently has 14 clubs with roughly 350 professional players, plus hundreds more in the First Division and youth teams. But the number of players tracked with proper data on a regular basis is under 15%. That means more than 85% of Vietnam's professional football workforce operates in an information blind spot. And in that blind spot, the forgotten ones multiply. I remember the summer of 2026, when I spent three straight months sitting at the fence of Lach Tray. I was 26, the only young reporter allowed by the coaching staff to observe training sessions. I followed a 21-year-old midfielder who had played only 47 minutes across an entire V.League season. There were no detailed statistics about him online. No article written about him. He existed on the club roster, and that was all. Instead of writing transfer rumors, I stayed in the locker room for two hours after every session, recording how he packed his boots, the captain's whispers, the hug from the familiar security guard. I wrote a 3,200-word piece published on the club website. It helped that player find a new home in the First Division and created a small media shock in the industry. But what I learned was not the power of writing. What I learned was: if just one person bothers to count, a forgotten one can be seen. The problem is that in Vietnam, too few people bother to count. And those who do count often count the wrong things. The locker room does not lie. It is only quiet enough for you to hear the truth. The truth I heard over years covering Vietnamese clubs is: we judge players by what is easiest to count, not what matters most. We count goals, assists, appearances. We do not count runs that drag defenders away, movements that create space, or unsuccessful duels that force opponents into sideways passes. Those things never appear on V.League stat sheets, and so players who excel at them are forgotten. Take an example from the national team itself. For years, foreign coaches arriving in Vietnam were often baffled by the lack of data on domestic players. They had to build their own tracking systems, hire analysts, or simply rely on gut feeling. This explains why some players perform brilliantly at club level but are never called up, while others with impressive stats contribute nothing. No one has enough data to distinguish what is real from what is illusion. I once witnessed a memorable case in 2026. A 24-year-old left-back at a mid-table V.League club had excellent defensive metrics by my observation: he won 68% of his duels, passed at 84% accuracy, and above all, had the ability to read situations and intercept before the opponent launched an attack. But no platform recorded those numbers. When a big club expressed interest in buying him, they looked only at appearances and yellow cards. He was undervalued and eventually moved elsewhere for a fee that did not reflect his worth. That is the price of the data gap. It does not only leave players forgotten, it leaves them underpriced. But the story does not stop there. If I only talk about Vietnam lacking data, I would just repeat a chorus everyone knows. What I want to dig deeper into is: when we start having data, are we using it correctly? In recent years, some V.League clubs have begun hiring data analysts. They import software from Europe, sign contracts with international stats platforms, and start measuring more things. That is a good signal. But I have observed a new problem: data is collected but not interpreted. Like the automated analysis I received at the top of this article — it has a framework, nine analytical dimensions, complete tables, but no substantive content because the input was empty. In Vietnam today, many clubs are falling into a similar trap. They have xG tables, but no one knows how to use them to adjust tactics. They have PPDA data, but do not understand that a sudden drop may signal fitness fatigue rather than tactical change. They have running-volume numbers, but cannot distinguish between effective running and useless running. The result is that data becomes decoration. It sits in reports, in presentation slides, in coaching staff meetings. But it changes no decision. And the forgotten players continue to be forgotten, now with an added layer of digital coating over that forgetting. In the summer of 2026, when the pandemic closed stadiums, I had a different experience. I was 29, standing in the empty stand of Lach Tray with 45,000 empty seats. The sea wind still blew, but there was no cheering to drown out the sound. I was there to meet a veteran 34-year-old goalkeeper who had just torn a ligament and was going through mild depression from playing in an atmosphere with no applause. I persuaded the coaching staff to let me interview him via video for fifteen consecutive sessions. No filming, only listening and taking notes. The piece titled "Crying Without an Audience" was later published in Bong Da magazine, helping that goalkeeper receive thousands of messages of encouragement, and the club decided to extend his contract by one year. In those fifteen sessions, what I remember most is a sentence he said in the eleventh: "When there is no audience, I realize I don't know who I play for." That sentence has nothing to do with data. But it has everything to do with what data cannot measure: motivation, emotion, and the existence of a person on the pitch. I tell this story to emphasize one thing: while we struggle to build data infrastructure, we may be forgetting the human dimension of players. And this is exactly the counter-intuitive point I want to lead you to. Everyone says Vietnamese football needs more data. I agree. But I also believe more data does not automatically mean better judgment. Look at developed football nations, where data has become the main scouting tool, and we see an under-discussed consequence: data is creating a new class of forgotten players — those who excel at what algorithms cannot measure. In England, Premier League academies have long been warned about this phenomenon. A player may have good xG but never be highly rated because the algorithm cannot measure the ability to inspire teammates, the ability to stay calm under high pressure, or the ability to read a game in ways that cannot be digitized. This is why many big clubs still maintain traditional scouting networks alongside data systems. In Vietnam, this risk is even greater. Because we do not yet have a proper scouting culture. If we leap straight into data without building a traditional observation foundation, we will create a new generation of players who fit the algorithm but not actual football. And players who do not fit the algorithm — like the 22-year-old midfielder at Lach Tray I observed at the beginning — will be forgotten a second time, this time by machines instead of human laziness. Moscow has snow, Hai Phong has sea wind. Football puts both into the same story. I once witnessed that in the summer of 2026, when I was sent to Russia for the World Cup at just 27. In the fan zone in Moscow, I met a 63-year-old man from Kien An, Hai Phong, who had walked three hundred kilometers across countries to support the national team, carrying an old flag from 2026. He could not speak English, but I spent two days as a self-appointed interpreter to tell his story on the World Cup homepage. That piece reached 50,000 readers — my first article to attract international attention. What I learned from that experience is: a small individual, placed in the right context, can connect with the entire global football village. But to connect, you must first see that person. And in Vietnam, we are missing many people simply because we lack the tools to see. Back to the empty analysis at the top. That analysis was not at fault. It merely reflected an input that was already empty. The problem lies in the information-supply stage. And in Vietnamese football, the information-supply stage is the most neglected. We have too many opinions, too many judgments, too many commentaries — but far too little foundational data to verify them. This is why I always tell young colleagues: start by counting. Before writing about tactics, count the passes. Before praising a striker, count the runs he makes without receiving the ball. Before criticizing a defender, count the times he covers for a teammate's mistake. Those numbers are not on any official stat sheet. You have to create them yourself. And when you create them, you will discover players nobody else sees. I go to the pitch not to see who scores, but to see who stands up after a missed shot. That is how I define my job as a training-ground observer. And in nineteen years, I have witnessed too many players who never got the chance to stand up, not because they fell, but because no one recorded the moment they fell to see that they could rise. Now, look at the broader picture. Vietnamese football is in a critical transition phase. The national team has made historic strides in continental competition. The V.League is attracting more investors. Youth academies are being built more professionally. But if data infrastructure does not keep up, we will continue to miss quiet talents. Every transfer window is a breakup. Those who stay are quieter than those who leave. In recent transfer windows, I watched V.League clubs spend billions of dong on foreign players with impressive records in other leagues, while domestic players performing well in the V.League itself were overlooked. This is not a story about ability. This is a story about information. Clubs buy foreign players because they have data on them from international platforms. They overlook domestic players because there is no equivalent data. In other words, information asymmetry is producing value asymmetry in the transfer market. This is one of the issues I believe will shape the future of Vietnamese football in the coming decade. I once had a long conversation with a technical director of a V.League club. He told me something that made me think a great deal: "If I had full data, I could have made better decisions on half the contracts I have ever signed." That was not personal regret. It was a confession about a system. So what is the solution? I do not believe in quick macro solutions. Building a national football data system is a multi-year task requiring coordinated investment from the federation, clubs, and media platforms. But there are small things each of us can do right now. Fans can start paying attention to players who never appear on front pages. Sports journalists can spend time observing training sessions instead of only showing up on match day. Coaches can keep more detailed notes on each player. These small actions, added together, will create a foundational data layer no system can replace. Wherever a ball rolls, there is a beat keeper. I am only a listener. But I believe if enough people listen and take notes, we will no longer have to watch forgotten ones disappear in silence. The story of the 22-year-old midfielder at Lach Tray is not over. I still go to the training ground every afternoon. I still take notes. I do not know whether he will find a new home, whether he will survive professional football. But I know one thing: if someone is patient enough to count what he does on the pitch, he will have a second chance. The 2026 World Cup in Qatar taught me a similar lesson, but on a different scale. At 31, I was hired by a digital platform as a senior expert in Qatar. But I did not only commentate. I brought recording equipment and called back to Hai Phong to organize a joint viewing at two in the morning for two hundred fans in a mini football pitch. On November 18, 2026, when Japan beat Germany 2-1, I recorded screams, breaking water bottles, and a young man crying because he missed his late father — the man who had taught him to watch football. My report contained seventeen direct quotes from the joint viewers, with not a single line about tactics. That is because I believe football is not just a game of numbers. It is a game of people, and people cannot be fully understood by looking only at data tables. But to understand a person, you must first see them. And in Vietnamese football, seeing a young reserve, a left-back at a mid-table club, a depressed veteran goalkeeper, or a 63-year-old fan who walked across borders — that alone is a revolutionary act. The lesson from the empty analysis at the top of this article is not a lesson about technology. It is a lesson about attention. When the input is empty, the output is empty. When we do not pay attention to our players, we cannot judge them. When we cannot judge them, we cannot develop them. And when we cannot develop them, we cannot build a sustainable football nation. There is one thing I want you to carry away after reading this. Next time you watch a V.League match, try to notice a player whose name you do not know. Watch how they move without the ball. Notice how they react after a teammate's mistake. Notice how they leave the pitch after the final whistle. You may discover something no data analyst has recorded. And if you are patient enough, you may become the first person to see a talent the whole football nation is overlooking. Lach Tray is empty, but the goal still holds the silhouette of a goalkeeper sitting and waiting. I still go to the pitch every afternoon. I still take notes. And I still believe that one day, the forgotten ones of Vietnamese football will be counted, seen, and given the chance they deserve. That is not a romantic dream. It is a technical objective. And like every other technical objective, it begins with having the right data, collected the right way, by the right people — those who bother to stand behind the training-ground fence, listen to the sound of boots on grass, and believe that what they are doing matters.
