I think that was what affected him mentally which made him not to be on his best performance last season. Osimhen does not want to be with them again and they don't want to let him go indirectly, which made them to put a hug price tag on him. If aOsimhen is still in Napoli, I don't think that he will be comfortable there anymore.
The Euros and Copa America is coming to an end toady and tomorrow, let see what is the fate of Osimhen as he might be needed by a new club because all clubs are reshuffling their team for a better performance next season.
I think if that kind of treatment from Napoli shown for Osimhen affects him mentally then he is definitely not a professional player because if only this kind of treatment makes him mentally deteriorate then he is not worthy of being a big player.
It's just that this will definitely interfere with performance because after all when a big club makes fun of its own players because of their performance it doesn't seem to be very good for a club because it doesn't reflect as a big club.
Coupled with the injury he suffered, it made Osimhen even worse and made Osimhen unable to restore the performance he had before.
Now there is really nothing to expect because even when he stays, Osimhen will not get good things when he continues to be at Napoli especially when they do not have a good relationship so why force Osimhen to stay.
