Vietnamese Football and the 'Empty Analysis' Disease

In a meeting room at the analysis centre of a V-League club, in the opening days of the season, a thick folder is laid on the table. Opening the first page, every field is blank. "Tactical analysis: insufficient information". "Financial structure: insufficient information". "Form lifecycle: insufficient information". The report is flawless in form, split into nine clear sections, with tables, diagrams, even a risk-warning panel. But by the final line, one realises a simple thing: it says nothing at all.

This is not a rare situation. It is the disease of an industry that runs on speed.

In my many years in this trade, I have seen no small number of analyses presented with solemnity, complete with every heading, yet utterly hollow in content. They are not wrong. They are merely meaningless. And the danger is that very few people can tell those two things apart.

In modern football, information is currency. Every V-League match generates thousands of data points: passes, distance covered, pressing intensity, pass-completion rate. Every training session generates hundreds of physical indicators. Yet in the press room, countless judgements are still delivered by feeling. "This team plays better". "That player has lost form". Such statements are not wrong, but they cannot be verified. And a judgement that cannot be verified cannot be corrected when it is mistaken.

That is why I began to believe in one principle: every number in football must serve an argument, and every argument must have evidence.

But I did not want to fall into the opposite trap either.

Many people think the cure for empty analysis is to stuff in as much data as possible. They roll out expected goals (xG), PPDA, progressive-pass metrics, and conclude as if that were the truth. But a table of numbers without context is as meaningless as a blank page.

Picture a striker with a very high expected-goals figure who does not score. People say he is unlucky. But look deeper, and perhaps he keeps taking the wrong positions, or perhaps the team plays in a way that does not serve him. The same figure, two explanations, and only direct observation can settle which is true.

That is why I always tell young people in this trade: go to the stadium.

I remember sitting in the stands at a V-League match, watching a player hailed as "irreplaceable". True, he produced lovely passes. But a sharp eye would see that he only touched the ball in safe zones, never entered the box, never applied pressure on the opposing back line. Aggregate statistics do not capture that. Only the human eye does.

Combining data with direct observation is the foundation of any analysis worth having.

Two decades ago, data-driven football analysis was a foreign idea. Today, even small European clubs have their own analysis departments, with staff tracking every metric of the opponent. Vietnamese football cannot stand outside that game. But receiving data is not the same as understanding data.

So why does the empty-analysis disease persist?

The pace of modern media does not allow slowness. A deep analysis needs three weeks to verify its data, but a hot take needs three minutes. The immediate reward goes to the quick, not the correct.

The crowd plays a part too. A bold but hollow claim draws thousands of comments, while a dry but accurate analysis earns a handful of shares. The algorithm rewards emotion, not truth.

But the most worrying factor is the absence of accountability. A coach who is wrong gets sacked. A player who underperforms gets dropped. But an analyst who presents an empty assessment pays almost no price at all. They simply delete the post and publish a new one.

I know this better than most. Years ago, I made a hot claim that a club should build its team around an attacking star. The piece exploded in traffic. At two in the morning, reviewing the tape, I realised the man who truly kept the machine running was a quiet defensive midfielder. I quietly deleted the post. But instead of staying silent, I wrote a new piece, arguing against myself.

Since then, I have built a habit: every analysis must contain a self-correction section.

Some say that lowers your credibility. I think the opposite. In a market flooded with hollow analyses, the only person worth trusting is the one willing to say "where was I wrong".

The story does not stop at the media. Clubs, too, are relearning how to make decisions. A team wanting to sign a player needs to know how many kilometres he covers per match, from where he shoots, in which zones he duels. An academy wanting to develop young players needs data on physical growth year by year. If those decisions rest on an empty report, the consequences will not stop at a deleted article.

Vietnamese football is in a phase of transformation. Clubs are starting to hire data analysts. Academies are starting to build tracking systems for young players. But if data is used only to decorate reports that are flawless in form, we will merely produce new blank pages.

The empty analysis I mentioned at the outset is not a failure. It is a warning. It teaches us that a system can look as professional as it likes and still mean nothing if there is no truth inside.

What football needs is not more data, but the courage to look straight at the data, and at the gaps within ourselves.

And you, when was the last time you believed an analysis simply because it was presented too beautifully?
