The truth is that the team that wants to add Osimhen to its team will have to bear a very large transfer fee. If Osimhen stays in Napoli, it will be better next year because there is the reality of Conte. He can even design the game around him and add new features to Osimhen. I think he is very talented. I think he will achieve better things by working with Antonio Conte for a year.
If Osimhen stays with Antonio Conte, maybe he will become more experienced. He might be able to become Serie A's top scorer next season. But I think Napoli should sell OSimhen this season. If they are interested in making money by selling Osimhen. Because if Napoli want to sell Osimhen next season, they will probably get a lower price. Because Osimhen's contract with Napoli expires in 2026. So teams will want to get Osimhen for free. Napoli management may be affected by this. For example, PSG did not make any money on the transfer of Mbappe
But if Napoli wants to dominate Serie A next season, then Napoli should definitely keep Osimhen in the squad. Because OSimhen is a fantastic player and his understanding with the Napoli squad is very good. So it can be assumed that he will be able to score a lot of goals with this team in the coming season.
