Hatayspor caused an upset in Matchday 12 by defeating the reigning champion of the Turkish Süper Lig, Galatasaray, with a score of 2-1, ending their long unbeaten streak.

The winning goals were scored by Honduran Rigoberto Rivas in the 14th minute and Didier Lamkel in the 55th minute. Wilfried Zaha repeated with a goal in the 28th minute for Galatasaray, but it proved insufficient.

With this result, Okan Buruk's team lost their unbeaten record in the domestic league, standing at 31 points in the first position, which they could lose if Fenerbahçe secures a victory this Sunday.
