Even for Osimhen, speculation about his future is of course very much in question because he is the target of many big teams at the moment. So there is a high possibility that Osimhen will also go to another team in this transfer window. Apart from that, if some of Napoli core players leave for another team in this transfer market, it will definitely have a big impact on their decline in performance next season. I think Napoli should be wary of this in order to be able to keep the core players from staying with them next season.
I think Osimhen is smart enough to bargain for a salary increase and still stay in Napoli, so that he can leave next season for a top-level club and with the same top salary. Now the only question is whether he will be able to spend the next season at the same level. If so, then the player will have a brilliant future. I just think that it will be much easier for Osimhen to do this now in Italy than in England, where, according to rumors, the footballer then dreams of moving.
Previously Napoli had said that they would be ready to release Osimhen at a high price in this transfer window. Thus, if a team wants to bring in Osimhen in this transfer window, they have to spend more money to bring in Osimhen.
Indeed, there are rumors that say Osimhen refused to sign a contract extension with Napoli. I think his attitude is most likely to want to ask for a bigger salary in the new proposal put forward by Napoli. If Napoli are unable to comply with Osimhen request, it is very likely that he will not sign a new contract and will relatively stay with the old contract until the end, he will leave on a free transfer. Well to maintain his best form next season it will be a big factor for him if he fails to shine in next season I think his release clause will drop significantly in next season.
Osimhen is considered to be the most important player in Napoli's squad. This young striker was in great form last season. He managed to score 26 goals in 32 Serie A matches. And since he's had a great season, and is slowly getting more experienced, it's only natural that he'll demand higher wages now. If Napoli are interested in keeping Osimhen in the squad, they will certainly have to pay high wages.
However, Napoli will likely decide to sell Osimhen. Because selling Osimhen at the moment would fetch a high price for the team. Rich teams like Manchester United, Chelsea, and PSG are interested in keeping Osimhen in the squad. However, Napoli is likely to demand more than 170 million for Osimhen. It's too much. I heard PSG is interested in spending 120 million for Osimhen. But Napoli rejected this offer.
