Lennart Karl continues to write his fairytale season at FC Bayern. The 17-year-old home-grown talent has now been rewarded with a historic jump in market value, putting him at the top of the league
In the middle of his first real professional season, Lennart Karl has reached a milestone that is rare even at FC Bayern. The Transfermarkt portal updated the market values of 496 Bundesliga players shortly before the winter break – and the biggest winner is in Munich. Karl has increased his market value by a whopping €40 million in a single update, jumping from €20 million to €60 million. A dimension that has never been seen before in the Bundesliga
This makes the 17-year-old not only the biggest winner of this update, but also the biggest market value gainer in Bundesliga history. Since the introduction of market values in 2004, no player has made such a massive leap within a single update. For a home-grown FC Bayern player, this is an honour – and a clear signal to the entire European market
From talent to top value in just six months

The speed of this development is particularly remarkable. As recently as mid-June, Karl’s market value was just €1.5 million. Six months later, the attacking midfielder is already one of the ten most valuable professionals in the entire Bundesliga – a development that is rare even for highly-rated super talents
In sporting terms, this upgrade is no coincidence. Karl has developed from a youth player to an integral part of Vincent Kompany’s professional plans in a very short space of time. With strong performances, wit, courage in one-on-one situations and an astonishing maturity for his age, he has not only earned himself playing time, but has also actively influenced games. Six goals in his first season at this level underline that this is not just short-term hype
FC Bayern is benefiting from something that has long been considered a strength internally: the courage to embrace youth. Karl’s breakthrough is a prime example of how opportunities arise when talent is given confidence – especially in phases when the squad is deliberately kept lean
Most valuable U17 player in the world – and now?
With his new market value, Karl is now the most valuable footballer in the world up to the age of 17. He also leaves all his peers behind him internationally. For FC Bayern, this is not only a sporting success, but also a strategic one. Karl has a long-term contract and the club has full control over his future
At the same time, expectations are growing along with his market value. But at Säbener Strasse, they are trying to take the next step in his development with a sense of proportion. The market value of 60 million euros is not a target, but a snapshot. The decisive factor will be how consistently Karl confirms his performances and how he deals with the new attention. There is no question that he has the talent, the mentality and the environment for it
Karl has long been more than just a promise. He is one of FC Bayern’s most valuable assets – both in sporting and economic terms. And his story seems to be just beginning.
