Galatasaray striker, Victor Osimhen scored a brace as they began their title defence with a 2-2 draw with Corum.
The Turkish champions went into the season opener as favourites against the newly-promoted side.
However, the Yellow and Red failed to take all three points.
Osimhen broke the deadlock in the 53rd minute of the match, squeezing the ball in from a tight angle.
But Corum drew level through Alexandros Kyziridis. It then took a shock lead after Jesus Ramirez scored.
Kyziridis was shown a red card and Galatasaray took advantage of their numerical superiority to score the equalizer, with Osimhen powering home a header.
