Galatasaray· Süper LigKaan Ayhan gewann viermal die türkische Meisterschaft, einmal den türkischen Pokal und einmal den türkischen Supercup. Zudem wurde er deutscher Zweitligameister und holte den Titel in der deutschen U19-Bundesliga.
Kaan Ayhan wurde in Gelsenkirchen geboren und begann seine Profikarriere in Deutschland, bevor er in die Türkei wechselte. Der defensive Mittelfeldspieler und Innenverteidiger feierte seine größten Erfolge bei Galatasaray und Schalke 04. Er ist bekannt für seine Vielseitigkeit in der Abwehr und im Mittelfeld.
Ayhan ist ein defensiv orientierter Spieler, der sowohl als Innenverteidiger als auch als defensiver Mittelfeldspieler agieren kann. Seine Stärken liegen im Stellungsspiel und in der Spieleröffnung, während er gelegentlich an Tempo und Zweikampfstärke mangelt. Er agiert als ruhender Pol in der Defensive und leitet das Spiel von hinten ein.
