I think Galatasaray made good decision by borrowing Osimhen from Napoli. It is surprising because Chelsea and Al Ahli also wanted him. But Napoli clearly does not want him anymore. Loan agreement says Osimhen can leave in January if another team offers to buy him. This is good for both Galatasaray who gets great player for a while and Napoli who can let go of player they do not need. I hope Osimhen plays well for Galatasaray. By the way he is a good player and will give his best.
If Napoli's coach wasn't Conte, maybe Osimhen would still be needed. But unfortunately Conte really wants Lukaku more. And it seems that Lukaku's style of play is more suited to Napoli's new coach, Conte, who has known Lukaku for quite a long time. Osimhen really wants to leave Napoli. This is what makes Napoli also want to let him go. If Osimhen wanted to stay from the start then Napoli would have definitely kept him. Unfortunately, Osimhen really wants to leave. But Osimhen's desire to leave turned out to be difficult. And several teams that made offers to Osimhen also failed to reach an agreement with the player. And in fact, Osimhen has no other choice but to be willing to go on loan at this time to Galatasaray. And yes, Galatasaray is indeed lucky. Because they can borrow a great striker like Osimhen.
