Galatasaray head coach Mustafa Denizli has resigned after only three months in charge of the Turkish giants.
With Gala unable to replicate the sort of form that won them the title last season, they are in fifth place and 16 points adrift of leaders Fenerbahce.
The resignation of 66-year-old Denizli ends his third spell in charge of Galatasaray, and a club statement said: "Mustafa Denizli has resigned as of March 1.
"We thank him for once again agreeing to take charge of the club in this period."
The club said development coach Orhan Atik would be placed in temporary charge.
