Osimhen is one of the best stars of the present time. One of Napoli's most important players would be wrong to call him that. But recently, for some reason, he may not have a good understanding with the club, that's why there are rumors that he will leave Napoli. As he is a young talented player it is only natural that top clubs in Europe will offer to sign him. Osimhen is more likely to move to the English Premier League. There is no chance of Osimhen going to Real Madrid because there are already some good quality players in the position Osimhen plays and there are rumors that Mbappe will join Real Madrid next season if all goes well then there is no chance of Osimhen going to Real Madrid. Maybe an offer from Manchester City or Chelsea next season.
There is a slight internal problem between Osimhen and the Napoli team and this problem has surfaced in the public, perhaps because of this it makes it seem like Osimhen is no longer playing wholeheartedly for the Napoli team.
And also Napoli's declining performance this season has had a big influence on Osimhen's comfort in remaining in this team because of course a quality player like Osimhen wants to be in a team that has the potential to become champions, whereas he didn't get that at Napoli this season.
Indeed, in my opinion, Osimhen would be better off moving to a top team for his future career development.
