I understand this situation better now but then again I think Victor Osimhen has no intention of leaving the club before now if not because the new coach of the team prefers Lukaku to him which is why I think the player decided to go else where since he wasn't favoured in the eyes of the manager. I think what is happening right now with Victor Osimhen should serve as a lesson to the other players when accepting a contract they should be sure of what they are agreeing to do that when things isn't working between them and the club they can easily move to another club without facing so much stress.
It seems like you missed the season before Lukaku joined Napoli because Osimhen had been at odds with the coach ever since which cost him his place in the first team.
It’s been almost three seasons since Osimhen said he wanted to leave Napoli but never reached an agreement so he was only loaned out.
This situation will not benefit Napoli when his contract expires so it would be right for Osimhen to be released to another club.
Several teams have been calling for his services but have not reached an agreement so far and I think this should be a consideration for both Napoli and Osimhen himself.
