Trabzonspor extended their lead at the top of the Super Lig table after beating Altay 2-1 away from home on Tuesday.
The Black Sea Storm came from behind with a second half brace from Andreas Cornelius to record another victory.
The visitors have been in brilliant form this season and have build up a 12 points lead over their nearest rival Konyaspor who are in second position.
Konyaspor could close the gap to nine points if they beat Hatayspor tonight away from home.
Trabzonspor are 17 points ahead of their nearest top four rival Fenerbahce.
Galatasaray meanwhile, dropped 21 points behind the leaders after losing 2-0 against Adana Demirspor.
Former Galatasaray winger Yunus Akgun scored a brace to add more misery to the Istanbul giants league campaign.
The Lions are however, just five points off 4th spot which would get them into European competition next season.
Additionally, the Yellow-Reds are doing well in Europe this term and have booked a place in the Europa League Round of 16, bypassing the Round of 32 after topping their group.
