Galatasaray is a huge club in a cosmopolitan capital playing in the Champions League and paying big salaries.Honestly surprised he wants to leave.
He could be a backup here for a year and he’s still young enough that plenty of teams would love to sign him for free.
Surprised he’d go to turkey instead of having his pick of countries.
That beats the hell out out just running a year of your career off the clock at under a manager that doesn't want you at age 27.
Best of luck to him. He didn't pay that big fee for himself and he's been nothing but professional.
