Trabzonspor responded strongly, but they couldn't equalize and went into halftime trailing by one goal.
Just a minute into the second half, Victor Osimhen scored a brilliant volley to double Galatasaray's lead. He then scored again three minutes after the hour mark to complete his brace.
Osimhen's two goals helped his team win their first title in Turkey since he joined Galatasaray on loan from Napoli. If Galatasaray wins the league this weekend, Osimhen could complete a double.
