The German-born Turkish international defender started his career in the German Bundesliga with Kaiserslautern before moving to Mainz and later on to Kayserispor in Turkey.
In his first season at Fener, Kaldirim was the team's main left-back playing a total of 41 matches however since the departure of coach Aykut Kocaman, Hasan Ali has played second fiddle to Caner Erkin and although he has certainly proved himself as a solid left-back he still failed to break through.
Now Turkish media outlets Sporx and Ajansspor are claiming that Schalke, Werder Bremen and Hamburg, among others, are aiming to sign the 25-year old.
Ajansspor are also claiming that Werder Bremen are prepared to offer 2.5 million euros to secure Kaldirim's services whose contract ends in June 2017.
Fenerbahce have previously signed Hasan Ali for 3.75 million euros from Kayserispor in 2012 and he has scored one goal in 62 appearances for the Yellow Canaries while he represented the Turkish national team on 16 occasions.
