The Empty Column: When Vietnamese Youth Football Scouting Judges From Nothing

Summer 2026, in a small corner office in Hamburg, I opened my regular player-tracking file and found a blank column. No player name. No data source. No date. Not a single metric. Only the file header and empty space below. A spreadsheet does not lie; it simply stays silent. Yet that silence is the most dangerous trap of the trade: when there is no information, people tend to invent conclusions rather than admit they know nothing.

I have seen it repeat in Vietnamese youth football. An academy sent a list of 40 U15 players with a single line: please assess. No minutes played, no preferred position, no dominant foot, no injury history. A few days later, a scouting report came back with three lines: good pace, potential, needs monitoring. Those three lines were not enough to judge a fifteen-year-old. But they were used as if they were, and they entered the file as fact.

Over the past decade, Vietnamese football has seen a wave of datafication at youth level. Centres such as PVF, HAGL JMG, Viettel and Nutifood began collecting GPS metrics, minutes played, passes, and duel win rates. Academy rankings were published. Recruitment drives expanded to thousands of children each year. From the outside, Vietnamese youth football is entering a digital era.

But alongside that wave is a gap few discuss: accurate, sufficient and verifiable data remains scarce. Most First and Second Division clubs have no standard recording system. National U15, U17 and U19 tournaments track goals and cards, but lack positional data, pressing metrics and passing maps. A scout assessing a U17 central midfielder usually has only appearances, goals, and a few short clips filmed by an acquaintance on a phone.

That is the condition I call analysis on an empty source. It is not exactly a lack of data, but data insufficient to support the conclusion one wants to draw. And our trade, at this moment, is tempted to fill the gap with feeling.

When data is insufficient, judgment should not appear. But it still appears — because the pressure to deliver a conclusion outweighs the pressure to be right.

I have followed German youth football for two decades. There, a scouting report on a U17 player is usually six to ten pages long: average position maps, touches per half, forward-pass rate, second-tier duels, behaviour when losing the ball, and at least three full recorded matches. Yet even with all of that, the final conclusion is often: more data needed.

My standard does not rest on the number of metrics. It rests on one simple principle: if you cannot state the source, the date and the subject, you must not state a conclusion. Because an empty conclusion is not harmless. It enters a player's file, follows that boy for years, and can shape an entire career.

I once watched Jann-Fiete Arp score 23 goals in 18 U19 matches for St. Pauli at just sixteen, standing 1.78m. Back then, many colleagues chased bigger names from famous academies. I built my own framework: fourteen metrics on positioning, ball-processing speed and movement inside the box. The result came not from a single number, but from cross-checking it against three recorded matches and two live viewings. My forecast — Arp stepping up to the first team in the 2026-2026 season — proved correct.

But I remember another case, and it haunts me more. At a U17 tournament in central Vietnam, a sixteen-year-old left-back was rated not quick enough after a single blurry match filmed from the stands. His file had exactly one line. No one checked again. Two years later, he vanished from the system. I do not know whether he was talented. That is precisely the problem: we concluded when we had no right to conclude.

The sediment layer of summer: I dug deep, and found a season never written. In it lie young players buried under lines of data that were wrong, insufficient, or left blank.

The irony is that many believe more data will solve everything. I do not think so. More wrong data only produces wrong conclusions faster. In many academies, the problem is not a shortage of metrics, but metrics collected without a guiding question. GPS records distance run, but not that the boy ran because he feared being abandoned. The spreadsheet records passes, but not that he dared not pass because a coach had just scolded him in front of the whole team.

A young player is not a polished gemstone. He is a broken piece of pottery still bearing the potter's fingerprints. And those fingerprints are in no spreadsheet.

The second trap is more dangerous: when the source is empty, people do not only invent conclusions — they invent confidence. A three-line report is presented like a ten-page report. Its certainty comes not from evidence, but from a confident tone. I call this the data illusion: seeing a chart and believing you understand a person.

For Vietnamese youth football, this is especially risky. Limited resources mean every misjudgment is an unrecoverable lost opportunity. A player cut from a list at fifteen usually gets no second chance. So the lesson from an empty analysis is not technical — it is humility.

At sixty, I have learned that data stops at the stadium gate. Inside, people play with fear and dreams. An empty file is not frightening in itself. What is frightening is the reflex to fill it with judgment. For Vietnamese youth football, perhaps the right question is not how many more metrics we need, but whether, when data is insufficient, we dare to say we do not know. If the answer is yes, that football will stop losing the children it never had time to see.
