Victor Osimhen had the best season of his professional career last season and thanks to the coach and staff of Napoli for bringing our the best from the Nigeria international.
There's been several rumours about his future and the next football home of Osimhen which hasn't been confirmed by the player or the manager. That being said, I don't think Victor Osimhen wouldn't leave Napoli this summer for another Italian club
While the risk of Osimhen heading to Milan is still unknown it appears doubtful that Ac Milan will make a long term acquisition given their emphasis on accessible players. The player existing Napoli contract and the Saudi Arabian offers add to the difficulty of the situation. It is less likely that Napoli will release Osimhen as a free agent to Milan because of the president view of him as a valued asset and the leading goal scorer in Serie A. Napoli might instead decide to sell him to another team in order to make money. If Osimhen does join Milan it will surely improve their attacking capability but as of now it seems dubious that the rumour will come to pass.
Osimhen's price is too high for a team like Ac Milan I don't know where the idea comes from to say Ac Milan trying to hire Osimhen for the next season but as far as I know, other teams in Serie A can't have enough money to hire this player for the next season and even if Napoli gets some offer for Osimhen from other teams, there will other teams like PSG with better financial situation.
But regardless of that, I think Napoli's first priority is to keep Osimhen for another season.
