On my computer screen, an extraction table appeared with exactly seven rows. Title: blank. Source: blank. Type: unclassified. One-sentence summary: empty. Information points: not a single line. Only one cell lit up like a lamp in a dark room — domain: football. I sat motionless before that table for a long time. It looked exactly like a match I once watched at the Nha Trang stadium: packed stands, roaring noise, and yet when the ball hit the net no one could remember where the final pass had come from. Plenty of noise, very little information.
I work as a sports commentator in Nha Trang. On the day I moved into the football desk of an online newspaper, my male colleagues smirked as they watched me carefully note down every pass of a young player. They said I was making things up. Three months later, that player — Pham Gia Hung, shirt number 10 — was called up to Vietnam's U23 side and scored twice in a Southeast Asian tournament. That is when I understood: most of what is called "football analysis" is really just noise rearranged to sound intelligent. That empty extraction table was never a technical error. It was a confession.
A football nation that talks much and records little
Vietnamese football lives in the age of numbers. Every V-League round, statistics platforms push out hundreds of metrics: distance covered, sprints, pass accuracy, duels won. On television, people read them out like a multiplication table. But when I tried to extract one specific article — the article I hoped would give me material to analyze — the result was a blank space. No title, no source, not one verifiable information point.
What matters is that this emptiness is not rare. It is the permanent state of a large share of the football content we consume every day. A sensational headline, a vague summary line, a quote with no clear source — and behind it all, an entire content-production system running on speed rather than verification. When an article has no title, no source, and no facts, then every comment about it — even the best comment — is merely talking about nothing.

I remember 2026, when I was sent to Russia to cover the World Cup. In the final, France beat Croatia 4-2 while holding only 39% possession. The whole world praised Didier Deschamps. I wrote a piece with a contrarian argument, and it reached over a million views in under an hour. But what I remember most is not the readership. What I remember most is the fear as I put pen to paper: without possession data in hand, my claim would have been nothing more than a meaningless shout in a crowd. France won, but football was the loser — that story has never grown old.
When metrics become a shield
Start with the most celebrated metric of all: distance covered. A midfielder who runs 12 km per match is praised as a "tireless machine." But distance does not measure purpose. A player who runs 12 km chasing a ball he never touches, dropping back to cover space that is never exploited, moving with the ball instead of moving to create space — that player is producing a beautiful number for a meaningless performance. I once sat for hours over a V-League data sheet, recounting every sprint, and found that nearly half of the winning team's sprints came from runs back toward their own goal to... do nothing at all.

This is the root problem: metrics measure what can be measured, not what matters. Pass accuracy is another example. A center-back who passes sideways and backward with 90% success will post a better number than a creative midfielder who completes only 74% but whose passes include four through-balls that open up goals. If you look only at 90 and 74, you hand the prize to the safe player and ignore the one who makes the difference. Football, like every field, tends to worship what is easy to count.
Then there is xG — expected goals. It is one of the best tools modern football analysis has produced. It tells us the quality of a chance, not just the quantity. But like any good tool, it gets abused. People use xG to draw conclusions about a match they never watched. They say "this team deserved to win because its xG was higher" as if football were an equation. xG cannot see the psychological pressure on a defender playing his last match before being sold, cannot see a goalkeeper who has just suffered a family tragedy, cannot see how a team crumbles mentally after conceding in the 88th minute.
There is another metric even more dangerous, because it does not come from the pitch but from social media: views, shares, engagement. We are increasingly measuring the value of a commentary by how many people read it, rather than by how many correct things it says. A wrong but sensational article will draw many times the engagement of a right but dry one. And when the market pays for engagement, engagement becomes the goal. This is the media's version of "distance covered": an effort metric that looks objective but can be inflated without creating real value.
In football, clean sheets are often inflated too. A defense with ten clean sheets is praised as a steel wall, but sometimes the reason is that their goalkeeper made many high-quality saves — meaning the defense actually left plenty of gaps. A clean sheet can signal solidity, or it can signal luck. Without shot-quality data, no one can tell the two apart. And in Vietnamese football, shot-quality data is still a luxury.
In the V-League the problem runs deeper: the data infrastructure is not open or trustworthy enough. Many matches lack full player-position data, many metrics are compiled manually by a small team, and as a result domestic analysis tends to circle only around what television replays — that is, what has already been framed for us. To analyze properly, you need real data. And to have real data, someone must be willing to spend money and time collecting it. That is a long-term investment the Vietnamese football market still does not want to make.
Youth development is the same. We often hear figures about how many players are trained each year, how many academies, how many youth tournaments. But quantity says nothing about quality. An academy that produces twenty players a year but none of whom reach the first team makes that number meaningless. What is worth measuring is the conversion rate — what percentage of trainees become professionals, what percentage survive in the V-League after three years. Those numbers are almost never published. And when data is not published, people assume everything is fine.

I remember 2026, when I was assigned to cover the transfer window of Nha Trang Football Club. A trusted agent showed me a loan contract for striker Nguyen Duc Anh, shirt number 9, to a second-tier club with a 20-billion-dong buyout clause. At the last minute, the club withdrew for lack of budget. I wrote a piece with meeting recordings attached. What I learned from that case was not the 20-billion figure. It was this: real data never sits on the scoreboard or the stats page. It sits in closed meetings, in midnight messages, in documents no one wants to make public. Every contract is a life turning a page — do not only ask the price.
Then in 2026, at the Euros, I declared on television that Italy would win because they won the ball in the opponent's half and knew the closing minutes by heart. When Italy beat England on penalties, my claim became a talking point. A former Italy international confirmed to me that coach Roberto Mancini taught the players to keep the ball for the final ten minutes. It was a small detail, but it was data. It was completely different from sitting back, looking at the scoreline, and guessing. Tactics will fade, but the story of belief will not.
I have one iron rule: before writing any controversial claim, I must check the data against at least three independent sources. That rule has saved me many times. There were moments I nearly wrote a piece criticizing a player for poor metrics, only to discover the metric was computed wrong, or computed in a match where he played a different position. Had I not checked, I would have contributed to the very noise system I criticize.
VAR is a perfect example of the confusion between noise and information. Every VAR decision spawns a sea of argument, and most of it rests not on the law but on team emotion. People do not ask "what does the law say," they ask "did my team get robbed." In that environment, a decent commentator has a duty to separate the law from loyalty. It is a thankless job, but it is the job.
That empty extraction table, then, is not an isolated phenomenon. It is the symptom of a long chain: content produced faster than the speed of verification, headlines written before facts are checked, and an entire media ecosystem running on feeling rather than evidence. When I tried to analyze an article that itself contained no information, I did not fail. I was looking straight at the nature of the problem.
Emptiness can be a form of honesty
Here I must argue against myself, because otherwise I am merely repeating the noise I criticize.
There is another way to read the empty extraction table: it is more honest than a full one. A system willing to admit "I have nothing" is more trustworthy than a system that always pretends to know everything. In my profession, the most frightening thing is not an empty analysis. The most frightening thing is an analysis stuffed with invented facts, grafted quotes, and untraceable statistics. I have seen articles citing a metric that no one — including the writer — could trace to its source. Those articles look far more professional. They are far more dangerous.
The real problem is not a lack of data. The real problem is a lack of honesty when facing a lack of data. A decent journalist, when there is no information, will say: "I have no information." A content producer, when there is no information, will invent something to fill the gap. The empty extraction table, in this sense, is an ethical reminder. It tells me: silence is better than a lie.
But I do not want to stop there, because silence alone is not enough. In the silence of empty stands, the data whispered things no one expected. In 2026, when the pandemic halted every league, I sank into gloom because there were no new matches to write about. To keep the fire alive, I began studying The Football Database. I found that from 2026 to 2026, away teams in the Premier League scored 43% of their goals in the final fifteen minutes. My series explained why crowd pressure is part of home advantage. An English football magazine shared it. The emptiness of the crowdless stadium, it turned out, was where the data spoke most clearly.
There is another trap writers like me easily fall into: nostalgia for a lost "pure football." People talk about an era when players played with heart, not with computers; an era when tactics had not yet killed improvisation. But that "era" never existed as we imagine. Football always had tactics, always had calculation, always had money. Only the tools changed. If I use nostalgia to avoid analysis, then I am doing exactly what I criticize in others.
So I choose between two extremes: do not fabricate, and do not give up. Emptiness is not the end point. It is the starting point of an honest investigation.
What remains after the noise
For years I have kept a black notebook recording small observations. In it are lines like: "Hung — through-ball, 34th minute, match against Da Nang youth." Those lines are nothing special. But when stitched together over time, they tell a story no summary can. There are talents buried under contemptuous glances, and I have watched them bloom.
Vietnamese football needs less noise and more notebooks. Fewer glossy summaries and more honest data sheets — even when those sheets are empty. More people willing to say "I don't know yet" before saying "I know for sure." Data gives me numbers, but the empty stands give me questions. And perhaps, in a football nation where everyone rushes to conclusions, the one who dares to ask the question is the one who moves first.
People call me a contrarian. I call myself a finder. The empty extraction table on my screen tonight will not last forever. But what it leaves behind — are we talking about football with evidence or with echo? — will linger for a long time, at least until someone patient enough answers it with real data.
