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.
Conte is one hell of a good coach and from what I believe is that if Antonio Conte wanted to work with both Lukaku and Osimhen it would have been possible but he only desire to work with Lukaku and not Osimhen, both strikers are good in different ways, Conte knows what he's doing. With fact that Osimhen wants to leave due to how the atmosphere is for him at Napoli, I think that's his decision to leave. If Conte wants Osimhen to stay he can as well talk to him to stay at least a season or two to help make the team stronger, other coaches are doing it to convince players who wants to leave to stay so this Osimhen's issue is something we all know that the new manager Antonio Conte doesn't want in his team so we don't need to blame either Conte or Osimhen is their choice, the player made the decision before the arrival of Antonio Conte, if I'm not mistaken.
If he didn't make that move to Galatasaray I assure you that his market value would have dropped and bigger clubs won't even consider going for him with huge amount to get his signature.
With this Galatasaray move he can even convince clubs like PSG to come back with a better offer because I know he'd play very well couple with the fact that Galatasaray are in the European competition so he still has the chance of making himself known. But my problem is him playing a half season with his new team, with that kind of welcome he received I expected him to give Galatasaray a full season loan because is very hard to get such welcome and love from the supporters.
