A football transfer is a bet, and most clubs lose it. Over the last ten completed seasons the 24 clubs that passed through the Belgian first division paid fees for 665 players and spent about €1.22bn doing it. We went through every one of those deals and asked a single, blunt question. Did the signing work?
On the strict test, the answer is no for roughly two out of three. Count a purchase as a hit only if the player became a regular in the league the season he arrived, or was sold inside three years for at least double his fee in profit, and 239 of the 665 clear the bar. That is 35.9%. The other 64% returned nothing measurable on the pitch and were never resold at a profit worth the name.
The strict test is unfair, though, and it is worth saying why before leaning on it. A player bought in January has half a season to prove himself. A 19-year-old from a smaller league often needs a year to find his feet. Judge every signing only on year one and you punish the two most ordinary things that happen to a new player. So we ran it again, this time taking the better of a player’s first two seasons.
Half, on the kind reading
On that fairer reading the hit-rate climbs to 50.5%. Exactly 336 of the 665 came good. And the gap between the two numbers is not noise. It is 98 players who looked like failures after one season and were regular starters by the second. Roughly a third of every signing that eventually works is a slow burner the single-season test would have written off.
Even so, read it the generous way and half of all paid signings never become regular contributors and never turn a profit on resale. That holds up when you check it for the obvious distortions. Strip out the recent cohorts whose resale window has not closed and the rate barely moves, so this is not an artefact of deals that have not had time to pay off. Half is half.
Spending more is the wrong lever
Which is the finding that should bother a sporting director most. Split the 665 deals by fee and the hit-rate barely moves.
| Fee paid | Hit-rate (best of first two seasons) |
|---|---|
| Under €0.5m | 47% |
| €0.5m to €1m | 54% |
| €1m to €2.5m | 50% |
| Over €2.5m | 54% |
Flat. The correlation between fee and success is +0.04, which is the statistician’s way of saying none. A club paying north of €2.5m hit at 54%, a coin-flip with a small tailwind, and a club spending under half a million hit at 47%. The premium bought almost nothing.
What did vary, enormously, was the club doing the buying. The best recruiters in the league landed well over 60% of their signings. The worst managed one in five. And the spread does not follow the money. The two biggest spenders of the decade both finished below the league average, while Union Saint-Gilloise hit 64.5% on mid-table money, the best return in the division, before selling the likes of Victor Boniface on at a profit. The variance is in the badge doing the buying, not the size of the cheque.
What a hit actually looks like
So if it is not the fee, what is it? The deals that worked share a profile, and it is specific enough to recruit toward.
Start with position. Attackers are the risk sink. Forwards are the most-bought players in the league and the least likely to deliver, becoming regulars just 38.8% of the time against 55.8% for defenders and around 54% for midfielders and goalkeepers. A 16-point gap sits between the position clubs spend most on and the ones that actually pay off.
Age tells the same story. The hit-rate peaks for players bought at 25 to 27, where 56.4% become regulars. Under-21s land at 40.9%. The prime-age outfielder is the safe bet. The teenager is the gamble, and clubs pay a premium for the gamble.
Where you buy from matters too. A proven player bought from a strong domestic side is a reliable signing, north of 80% from the league’s better academies. The same money spent at the bottom of the table is closer to a coin-flip. Fit and profile carry the signal that the fee does not.
Two failures, or two strategies
One nuance keeps the picture honest. The two ways a signing “fails” are often two different bets. A young forward who never becomes a regular is not always a mistake. Under-21 attackers came good on the pitch only a third of the time, but were sold on for profit roughly three times as often as the average signing. That is a buy-to-trade play, and judged as one it works. The prime-age outfielder is the mirror image, bought to play and almost never resold. Score them on the same sheet and you misread both, which is why we keep on-pitch return and profitable resale as two separate numbers, not one verdict.
The bet you can actually improve
None of this says transfers are unwinnable. It says the lever most clubs reach for, spend more, is the wrong one. Ten Belgian seasons of fees, appearances and minutes point at a different lever. Recruit for the right profile, buy players who fit the side you already have, and give the ones who need it a season to settle, and you are working on the half of the equation that actually moves.
That is the half we built gaffer to work on. Not to tell you who is good, the whole league can see who is good. To tell you who fits, before you spend the €2.5m finding out the hard way.
