Former Manchester City assistant coach Domenec Torrent has taken charge of Galatasaray.
The Spaniard was set to become Fatih Terim's assistant, but Gala president Burak Elmas has decided to give him the top job.
Elmas said, "I have spoken with people with whom Torrent has worked in the past. For now we believe that we have chosen the most appropriate option for our football strategy.
"When Torrent takes office, we consider looking for a Turkish assistant to accompany him. We have spoken with some already."
On Gala legend Terim's departure, Elmas explained, "I will always continue talking to 'Mr. Fatih'. We have also talked about how to benefit from his ideas," after insisting that a change of coach "is not an easy decision".
