I agree with you. Osimhen is not a footballer with an extremely bad behavior. He is a good professional. After the Bologna game where Osimhen missed a penalty, the club's official social media account posted a video mocking Osimhen. I think that's the knot and the starting point of the problems. Osimhen was offended by that post and nothing was ever the same again. The best thing for Osimhen is not to play for Napoli anymore. I'm sure he will be very happy at Galatasaray and he will give a unique performance. And after one season at Galatasaray, he can play for Chelsea or Paris Saint Germain.
But you agree that Osimhen has a difficult character, after Spalletti left Napoli the team's results stopped being so good, conflicts for Osimhen became a common thing, and not only with coaches. Maybe he thought too much of himself, but one successful season is not enough to become a world-class forward, then his results began to decline, and his character was the reason that he was not in the application for the first matches of Napoli. Let me be wrong and all his problems will remain in Napoli, but if something similar happens in Galatasaray, then it will be his obvious problem.
