I know Napoli got a rich owner and he can have enough money to make Osimhem stay in Napoli for the next season and since Victor Osimhem is a young player he can easily be sold for a expensive price in the next season if he improves himself. But since there are many tempting offers for Osimhem in the next season from teams like Real Madrid I think Napoli should start seeking an alternative player to replace Osimhem next season, otherwise, they will have problems just like what happened in the game against Ac Milan they failed without Osimhem.
The team should provide Osimhen enough money so that he will be interested in sticking with the team, because we all know that if a player becomes a great player, he will feel the desire to better himself by joining another team. I'm hearing rumors that Osimhen is going to be sold because many teams are coming for him, and I believe every team will spend any amount of money to get him.
My opinion is that, Since Napoli players can't perform well without Osimhen, it would be better if they made him a sizable offer or found another intelligent player. If Osimhen left the team, the team would suffer. This is proven by looking at the team's matches this season.
