It must be very difficult for him to decide whether to stay or leave. But on the other hand this is an opportunity for him to join another big team. But the problem is whether he will continue his performance with the new team or vice versa. Because it is not uncommon for players who are good when playing in the old team, but fail when moving due to several factors, one of which is adaptation. He had to consider carefully before deciding.
The discussion about Osimhen is now getting hotter, lots of big clubs want to ask for her hand, one of which is Manchester United. And now a statement has been circulated that Osimhen has confirmed that so far he will stay at Napoli. Yes, it's true, in fact, he could have gone to join another club, but apart from all that, on the other hand, he had a lot to prepare for, the adaptation factor might be the thing that made the striker reluctant to leave, because it was difficult to adapt to a new team new game.
Yes, it will be a tough decision for Osimhen because he himself at Napoli for this season has achieved good enough that it would be a shame if he had to leave Napoli and had to adapt again to the new team that would sign a contract with him.
What you say seems to have a point because Napoli will definitely never accept the departure of Osimhen easily because he is one of the talented players who is quite good.
Maybe there will be another offer to be able to extend Osimhen at Napoli for at least one or two seasons.
It is reported Real Madrid is in the midst of making an approach with him hoping to sign him, as they are in need of a striker to replace Benzema. But it seems that the plans of all the clubs that want to ask for her hand will fail because the Napoli management has emphasized several times that they have absolutely no intention of selling Osimhen to any club and that the transaction will never happen. And finally, it is reported that Napoli is ready to award a new contract for Osimhen after the promising performances from the Nigerian striker.
