Why Is a 20-Year-Old Footballer Worth More Than a 28-Year-Old Star?

Football transfer fees used to track fairly closely with how well a player was actually performing right now. That’s no longer really true.

Clubs today will regularly pay more for a promising 20-year-old with modest senior stats than for a proven 28-year-old who’s been outplaying him every week, and the gap keeps getting wider.

It’s a resale calculation, not just a talent one

The shift comes down to how modern clubs think about transfer fees: not as a straightforward purchase, but as an investment with a resale value attached.

A 20-year-old signed today still has, in theory, most of a career left to sell on again in three or four years if things don’t work out, at a similar or higher fee. A 28-year-old is already past the age most clubs consider the peak of resale value, meaning whatever a club pays for him is largely money they’ll never see again once his contract runs down.

Jude Bellingham’s move to Real Madrid at 20 and Kylian Mbappé’s rise through his teenage years at Monaco and PSG are both good examples of this logic playing out in real fees: clubs paying enormous premiums for players whose value lies as much in years of future upside as in what they’ve already proven on the pitch.

Contract length plays its own role

Age isn’t the only factor driving this. A player with several years left on his contract gives his club far more leverage than one entering the final year of a deal, since the buying club knows a player heading toward free agency will only get cheaper to sign, not more expensive. That’s part of why clubs increasingly try to extend contracts for their most valuable young players years in advance, locking in higher future fees before a rival can simply wait them out.

Position matters too. Certain roles, like out-and-out goal scorers or ball-playing centre-backs, are simply rarer in the market at any given moment, and scarcity alone can push valuations well beyond what current form would suggest.

A market that’s stopped rewarding the present

The result is a transfer market where the best current performer isn’t necessarily the most expensive one. Established stars in their late twenties, even ones still playing at a genuinely elite level, often see their valuations plateau or even decline, purely because the sport’s financial models treat their remaining prime years as a shrinking asset rather than a guaranteed one.

For fans, it can be a jarring thing to watch. A veteran having arguably his best season can get transferred for a fraction of what a much younger, less proven player commands, not because anyone doubts who’s better right now, but because one of them still has resale value left and the other doesn’t.

This isn’t purely a modern phenomenon, but the scale of it has grown enormously as transfer fees themselves have exploded. A decade ago, the gap in valuation between a promising 20-year-old and a proven veteran was noticeable but rarely dramatic. Today, that same gap can run into tens of millions, purely because clubs have gotten far more sophisticated about treating a squad as a portfolio of assets to be managed for future value, rather than simply a group of players assembled to win matches this season.

Does it make sense for a football club to essentially value a player’s future more than his present form, or does that kind of thinking risk missing out on players who are genuinely at their best right now?
