The 525th CIES Football Observatory Weekly Post presents the players worldwide whose transfer value* is likely to increase the most in absolute terms over the next six months without contract extension and according to a scenario predicting the same performance as in the last six months, both individually (minutes played, starting 11 rate, goal frequency, etc.) and collectively (results).
Ivorian winger Yan Diomandé (RB Leipzig) tops the rankings with a projected increase of €40.1 million. His current value is indeed estimated at €45.7 million, while his expected value on 10 June 2026, according to the scenario described above, is €85.8 million. Newcastle United's German Nick Woltemade (+€26.2 million) and another Ivorian, Bazoumana Touré of Hoffenheim (+€23.9 million), complete the podium.
In total, the published list includes no fewer than 169 players active in 23 different leagues. The projected increase in their transfer value over the next six months is at least €5 million. This free tool, on the other hand, presents the highest-valued player per club in 67 leagues around the world. However, assessments for all players are available to professionals via a paid platform.
