The Empty Dossier and the Trap of the Perfect Conclusion

The Empty Dossier and the Trap of the Perfect Conclusion

In March 2026, at the training centre of a major academy in Munich, I sat in front of a four-page scouting report on a sixteen-year-old midfielder. Four blank pages. Not because the scout was lazy. He had filled in the date, the name, the signature, the title. But the one section that mattered most — whether this boy was improving or not — was empty. Every box held a single dash. I sat quietly for a long while before saying anything, and when I spoke, I chose not to recommend anyone at all.

That day I told myself I was being cautious. Looking back, I understood I was protecting a foundation by refusing to build another storey. The boy left that same summer, for another academy. The dash on that blank page has stayed with me ever since.

Context: every academy stockpiles, few bother to dig

European youth football runs on a quiet belief: the more players on the books, the more chances of finding a star. A big German academy can manage three hundred children across age groups at once, each with a personal file, a tracking coach, a development plan. From outside, it looks like a perfect machine. From inside, it is a pile of stacked dossiers, most of which will never be read again.

I used to believe a player development adviser's job was to read a lot, watch a lot, then pass judgement. The longer I worked, the more I realised the hardest part is not passing judgement. The hardest part is knowing when you have no basis to pass judgement. In an environment where everyone wants a firm answer, saying "I don't have enough data" is treated as weakness.

I have often seen the opposite. A report filled to the brim, with not a single empty box, tends to reassure a committee far more than a report with a few notes reading "needs further monitoring." That reassurance spreads easily. It makes people around the table forget one simple thing: a report that is complete in form is not the same as a report that is complete in substance. Some boxes are filled with words rather than with proof.

Two things are often conflated. A "complete" dossier is one missing no section. A "correct" dossier is one where every section holds up under questioning. Those two standards are far apart, and in youth football the gap is blurred by time pressure. Each season, hundreds of promotion or release decisions are made in meetings lasting a few hours, where a report that looks complete drifts through far more easily than an honest report saying it does not yet know.

When I look at Vietnamese youth football, I see a paradox. The data systems are young, but the pressure to produce conclusions is not small at all. Newly founded academies, new generations of players, and fan expectation all create pressure to announce early. I hope those working in youth development there keep the patience I once lost. Every sediment layer has its own rules, and the rules of youth football bow to no imported model.

The silence in that March 2026 report, then, turned out to be the most honest part of the whole file. It hid behind no index. It simply admitted the writer had not observed enough to conclude.

What makes an indicator trustworthy

Ten years in the job taught me one non-negotiable principle: every young player must be assessed by a minimum of three independent verifying indicators. Not three indicators measuring the same thing. Three indicators measuring three different facets of the same person.

Take pass accuracy. It is the most beloved indicator in scouting reports, and the most misleading. A sixteen-year-old midfielder with seventy-eight per cent pass accuracy in the Bundesliga U17 sounds impressive. But the number does not tell you whether he passes short or long, under pressure or unmarked, forward or sideways. A player who always passes sideways will have higher accuracy than one who breaks defensive lines. Looking at a percentage, people easily assume the two are alike.

The second indicator I always require is position and speed data measured by a global positioning system. In 2026 this was still a new tool at many academies. A sixteen-year-old midfielder's top speed of twenty-eight kilometres per hour was below the team average. That figure made the committee hesitate. But top speed does not measure game reading, does not measure the moment of acceleration, does not measure the ability to hold the ball in tight spaces. A player can have a modest top speed and still be first to the ball over the first three metres — the distance that decides most duels in elite football.

The third indicator is the hardest to measure and the most important: the ability to learn. At sixteen, a player still has ten years to grow. What matters is not current level but the slope of the progress curve. To measure that slope, you need at least two observation points, ideally three, spaced months apart. No machine does that for you.

Three indicators, three time points, three sources of data. That is the minimum threshold for a conclusion to be called a conclusion.

There is a subtle distinction I took years to grasp. There are descriptive indicators, and predictive ones. Pass accuracy describes what happened. It does not predict what will happen. A good descriptive indicator can reassure you about the present, but it does nothing for you in the future. Predictive indicators, by contrast, are hard to see, hard to measure, and demand far more observation time. That is why they rarely appear in hastily written reports.

If I must retell the March 2026 story honestly, I must include my own disadvantage. That day, the committee argued fiercely. Some thought I was too rigid. Some thought speed data was only part of the picture. I held my position, and the boy left. Perhaps I was right to wait. Perhaps I was wrong to wait so long. To this day I dare not claim certainty either way. That very uncertainty is what I want to hand down to my successors.

The Russian summer and the wrong verdicts

In July 2026, at the World Cup in Russia, I watched a nineteen-year-old Frenchman throw the entire Argentina defence into chaos in the knockout round. Kylian Mbappé scored, accelerated, and went past seasoned defenders as if they were standing still. It was a performance that made anyone stand up. But what kept me awake was not the performance. What kept me awake was what I found when I reopened my own old files.

I compared the data on Mbappé with the data on the sixteen-year-old midfielder I had once assessed in Munich. Good technique, high speed, physicality underrated by traditional evaluation scales. The data pattern almost matched. The difference was that one was seen by the whole world while the other was buried by a report.

I decided to do something I should have done years earlier: re-analyse every player under twenty who had started a knockout match in a major tournament over the past decade, cross-referencing the reasons they had once been rejected by German academies. The result forced me to write a forty-page internal memo. Of the nineteen players under twenty who started a knockout match at the 2026 tournament, most had once been judged to lack physicality, lack speed, or both. Very many of them had been discarded by a confident evaluation system.

That forty-page memo was not an indictment aimed at anyone. It was a self-audit. I named it with a concept of my own: the scouting recovery index. The idea is simple. Every time I reject a player, I must record the reason with a specific criterion. Years later, I return to check whether that criterion genuinely predicted the future. If a player rejected for low top speed later succeeds at the top, then the fault lies with my criterion, not with him.

This method takes time and is sometimes painful. The scouting recovery index gives me no extra confidence that I am right. It only tells me how many times I have been wrong.

A solid foundation before adding storeys

Since the Russian summer, I have shifted entirely to a different working method. I no longer ask how good a player is. I ask whether I have three layers of evidence to answer. The first layer is objective data: speed, distance covered, number of accelerations, touches in dangerous areas. The second layer is direct observation: body position, timing of off-ball movement, reaction after losing the ball. The third layer is historical record: what that player did over the previous two or three seasons, and what changed over time.

Those three layers stack like geological strata. A single beautiful move is only the top layer. To know who a player truly is, you must dig through the sediment of many seasons. Because old files never die; they only wait for someone patient enough to read them again.

The problem in scouting is not a shortage of tools. The problem is that tools multiply while patience shrinks. When I entered the profession, a good report required months of observation. Now an app can produce a player's score after uploading a few video clips. People assume that faster information processing equals better decisions. That is true for some tasks, and entirely false for judging human beings.

A contrarian angle

Most football debate today is ruled by decisive verdicts. Everyone wants a tidy answer. Who won this match, whether that player is talented, whether this coach has been sacked. That instinct spills into scouting. A scout who names a "future star" list gets remembered. A cautious scout who says he needs more data is called indecisive.

But the most dangerous report has never been the empty one. An empty report warns you itself. The dangerous one is a report that looks full but is actually built on empty data layers. It reassures you. It makes you sign. It makes you discard a player without ever knowing you leaned on a box filled with guesswork.

I have fallen into this trap. In 2026 I declined to recommend a promotion because I trusted a single indicator. That day, my decision sounded reasonable. It was recorded in clear words, properly signed, filed away. That very feeling of certainty is what I must guard against. I do not trust my eyes; I trust what the files leave behind. But I must also trust the blanks in the files, because they tell me the limits of myself.

The temptation of a confident conclusion is so strong it is easily mistaken for competence. Meanwhile, the ability to say calmly, "I do not know yet," is almost never rewarded. A conservative decision can bury talent, but it keeps the foundation from collapsing. And between those two costs, the trade usually teaches people to pick the cheaper one now and pay a dearer one later.

This industry rewards decisiveness and punishes hesitation. But a football nation that wants to survive for decades needs both. It needs people willing to conclude, and people brave enough to say the time for concluding has not come. If only the first remain, we will have plenty of beautiful reports and very few talents saved.

What I want to leave behind

At fifty-five, I no longer try to prove I am right. I have shifted my work to something else: teaching young people to read a dossier before they learn to write a conclusion. Whenever someone on my team confidently judges a player, I ask three questions. How many seasons have you observed? How many independent indicators do you have? And have you recorded what you do not know? If all three answers are thin, then the judgement is a single moment, not yet a sediment layer.

Youth football is a geological layer not yet excavated; do not rush to pour concrete over it. Every layer tells a story, if only we care to dig deep enough. The job of the person keeping the files, after all, is to keep that story intact for the next reader — even when the most honest part of it is a single dash.
