As Xhaka approaches his 34th birthday, he may consider a new challenge. There have been reports that he is open to joining Besiktas, a Turkish club that is looking to strengthen its midfield.

Besiktas fans are reportedly positive about the idea of Xhaka joining the team, but Sunderland will likely hope that the speculation about his exit subsides in the coming weeks and months.

Xhaka is a crucial player for Sunderland, and the team will want to keep him for as long as possible.
