The opening goal of the game came from an Osimhen header off a Dries Mertens corner kick and deflected off a PAOK defender into the net.
PAOK managed to equalise before halftime, but Galatasaray were able to take the lead in the second half from Osimhen's headed pass that found teammate Yunus, who fired home a powerful shot to secure the 2-1 victory.
Mauro Icardi then rounded up the game with the third goal after replacing Osimhen, who provided his third assist of the season.
Despite not having scored a goal for his new team yet, the Super Eagles star has created opportunities for his teammates.
