You think so, but last night Napoli announced that Osimhen's contract has been extended until 2027. So they still have expectations from him. Also, his release date at the end of 2025 has ended. He announced that they will stay on loan at Galatasaray until the end of the season. The Nigerian is a really quality forward, but I don't know what kind of problems they have. Conte and the others should work together again to solve this.
I think it's impossible, Osimhen will not work with Napoli again, I'm sure of that and regarding the contract extension, Napoli probably doesn't want to lose Osimhen for nothing.
From what happened this season, we can conclude that the relationship between Osimhen and Napoli management is not good.
Osimhen is indeed a fairly qualified player, but he was not included in Conte's plan to build the Napoli team for this season, so clearly there is disharmony between Osimhen's relationship with Napoli management or Conte.
