Galatasaray crushed Kasimpasa 4-1 at the Recep Tayyip Erdoğan stadium on Sunday to close the gap with league leaders Basaksehir to just three points.
Trezeguet gave the home side the lead on 14 minutes but Belhanda was quick to equalise just six-minutes later.
Sofiane Feghouli ended up being the star of the show scoring his first career hat-trick.

The Algeria international now has seven goals and two assists in all competitions this season.
Former Kasimpasa striker Mbaye Diagne started for the Lions but failed to get his name on the scoresheet.
The home side have lost six of their last seven games following the sale of Diagne to Galatasaray.
