Trabzonspor are set to face a transfer battle with Besiktas for the signature of Andre Onana, the Cameroonian goalkeeper who impressed during his loan spell with the Black Sea Storm. Onana, who is currently on loan at Trabzonspor, has been a key player for the club, helping them win the Turkish Cup. However, Manchester United, who own Onana's contract, are keen to sell him and have reportedly received interest from Besiktas. The Turkish club are believed to be willing to offer a significant transfer fee for Onana, which could make it difficult for Trabzonspor to match. Despite this, Trabzonspor are determined to keep Onana and are exploring all options to make the transfer happen. The club's management is confident that Onana will be a key player for them in the future and are willing to do whatever it takes to keep him. Meanwhile, Besiktas are also interested in signing Onana and are believed to be in talks with Manchester United over a potential transfer. The transfer battle between Trabzonspor and Besiktas is set to be one of the most closely watched in the Turkish transfer market this summer.
