The Istanbul giants fell behind to their opponents from Ankara when Burhan Eser scored after 26 minutes.

However Galatasaray had victory wrapped up by half-time thanks to goals from Brazilian midfielder Lincoln, Czech striker Milan Baros and highly-rated young midfielder Arda Turan.

Galatasaray were without Australian winger Harry Kewell, however, and he faces a spell on the sidelines.

The former Leeds and Liverpool player will have surgery on a hernia problem on Monday in Australia.
