Well I say something, Oshimen's performance is not entirely his fault, it is also the fault of his coach, if the coach does not give him freedom to play as he makes his plays, he cannot do anything, he is tied, he has to follow the system under which the coach has assigned him, then in Serie A, Napoli was very bad, you can't deny it, they also had their good moment when they were champions, but times change, and football changes too, so now things are different for him, he already has other offers, PSG and Chelsea, either of the two teams would do him well, out of necessity it would be spectacular if he went to Chelsea who need to do something now.
Changing coaches which occurs 3 times in one season certainly affects the performance of the players and that is what made Osimhen fail to show his best form last season. It's not the player fault if we look into it in depth because the big mistake was of course the owner of Napoli who fired Spalletti which made the team situation even more chaotic with the new coach. So, last season must be a valuable lesson for the Napoli team or owner, where he must fully trust the coach he appointed.
It is not certain that Osimhen will stay with Napoli even though he is still under contract. Of course, if Napoli and Osimhen have agreed to separate then that will happen. But for now it seems like there is no team that is really serious about recruiting Osimhen. Osimhen is a player of quite good quality after he succeeded in bringing Napoli to the Scudetto trophy in the previous season so he is still a target for top European teams in this transfer market.
