The match at Antalya's home stadium saw a resilient home team despite being down 0-2 in the 36th minute. Galatasaray found the opening goal in the 24th minute when Portuguese winger Armindo Bruma found the net after a well-executed give-and-go with his countryman Josue Pesquiera.
The Lions went up by two goals only 12 minutes later, and this time Derdiyok found the net with a beautiful strike outside the penalty area.
However, Antalyaspor did not give up and pulled one back in the 44th minute, when Galatasaray defender Aurelien Chedjou made a grave mistake and lost the ball to his countryman Cameroonian Etame Mbilla, who did not miss the one-on-one opportunity and beat goalkeeper Fernando Muslera.
Antalyaspor levelled the match in the 53rd minute, and this time Deniz Kadah found the net after a low-cross from Brazilian midfielder Danilo Sousa Campos.
Galatasaray missed several goal chances until the last second, when Derdiyok found the net with a header shot to Selcuk Inan's free-kick cross.
With the win, Galatasaray boosted their points total to 43 and got the number three spot back from Fenerbahce, who defeated Osmanlispor 1-0 on Sunday evening.
