Coach Roberto Mancini has left Galatasaray by mutual consent after one season, the club has announced.
The 49-year-old Italian manager joined the Turkish giants on a three-year deal - after being sacked by Manchester City at the end of the 2012-13 campaign - and led the Istanbul-based club to a second-placed league finish and Turkish Cup victory last term.
Galatasaray also progressed to the Champions League round of 16 - where they were knocked out by Chelsea in the round of 16.
Mancini has also coached Fiorentina, Lazio and Inter Milan, with recent speculation linking him with a return to Italy.
