The 53-year-old has been sacked by the Turkish club, with Igor Tudor expected to leave Karabukspor to take charge
Galatasaray have confirmed the departure of head coach Jan Olde Riekerink, with Igor Tudor expected to be named his successor.
Riekerink secured a Turkish Cup final victory over Fenerbahce in May last year but the 53-year-old has struggled to find consistent results in the Super Lig, with Galatasaray five points adrift of leaders Besiktas after 20 matches.
Club chairman Dursun Ozbek announced on Tuesday that Rierkerink has been informed of his dismissal and confirmed that a replacement coach will be appointed imminently.
