N/A – When football analysis dares to say “not enough data”

I have just read a sports analysis report whose final conclusion is not a tactical discovery. The final line is N/A – insufficient information. There is no data about a match, no number about a player, no confirmed transfer. A machine created to dissect football stopped and said: I cannot speak. Moscow has never heard anyone speak as bluntly as I do, so they call it prophecy; but today the blunt speaker is not me — it is a process willing to admit its own emptiness.

This is a two-stage workflow. Stage one extracts title, facts, core viewpoints, involved entities and source quality. Stage two is supposed to use that material to examine nine dimensions: tactics and technique, finance and transfers, results and public opinion, league context, governance, dressing-room management, risk profile, media narrative, and the wider football industry. But when stage two opened the box, it received a blank sheet. Every field was empty.

In the last three matches I have watched, I will not name the club because I do not have enough verified data. A heatmap may look as beautiful as a star chart, but it only records movement. It does not tell you whether a player runs because of the system, because of instinct, or because of fear. Football analysis should not begin with a map. It should begin with the gap that has not yet been filled.

The nine analytical dimensions are not decorative boxes. They are nine pairs of boots that must touch the grass. If there is no information, they all hit air. A club with transparent finances can provide trustworthy transfer figures. A team built on pressing deserves to be assessed through PPDA. If no club is named in the first place, every number is fortune-telling. Data analysis is not cooking numbers; data analysis is having the courage to say when there are no numbers to cook.

Many people confuse deep analysis with long writing. I have read 5,496-word articles that are smooth on the outside and empty inside. An algorithm can generate five thousand words from a blank page. The danger is not the length; it is readers trusting length as evidence of depth. That report was not long, but it was honest. It repeated the same answer — not enough information, cannot assess — across all nine dimensions. To me, that repetition is a wall against fabrication.

I have a hot-headed past. In 2026, after Germany lost to Mexico in Moscow, I proclaimed that German football was dead. That video drew millions of views. When the adrenaline faded, I realised I had ignored a generation of young players improving month by month. A listener sent me three lines of data, and all three showed I had generalised too early. I did not delete the video. I went on air, apologised, and promised to check numbers twice before making a final judgment. Since then, whenever I want to provoke, I look for a number to support me. If there is no number, I say clearly: this is a momentary emotion, not analysis.

Where could I be wrong? Some readers might say a report full of N/A is useless because it answers no football question. They are right. But its value lies underneath: it teaches us to distinguish between having no answer and refusing to tell the truth. If we overuse “not enough data” as an excuse, we will damage the very shield that protects honesty. The line between discipline and laziness is as thin as a ball waiting on the goal line.

Better to be a lone contrarian in a studio than a voice reading someone else’s script. I want to say this to everyone who audits data in sports newsrooms: do not be afraid of being criticised for saying you lack data. Be afraid when you use three charts to build a story that never happened. When did German football die? When it believed it would win simply because it always won. Vietnamese football can die the same way if all of us believe we must always have an answer, even when there is no question.

Let us call things by their real name: this document is not a football analysis. It is a record of an analysis system that stopped at the gate of missing sources. In my industry, that kind of report is usually thrown into the bin because it has no sensational headline. But I want to put it on the table because it teaches me something: before analysing anyone, ask where the data comes from; before judging a team, ask who confirmed the numbers. If we do not do that, we are walking into an offside trap of our own making.

The report closed with a short sentence: it contains no football conclusions because no football source was provided. I will add a testable prediction: within two V.League seasons, a club will pay a heavy price for signing a player based on a beautiful heatmap while ignoring how that player reacts under pressure from two defenders. When that happens, those who laughed at “N/A – insufficient information” will understand why it was one of the bravest lines I have read this year.
