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.
Victor Osimhen's contract with Napoli is until next season, so indeed with the dispute with Conte since the beginning of Conte's arrival as Napoli coach, the two did not have a harmonious relationship, so it was only right for Napoli to sell him, but now there are several problems, namely transfer fee constraints and also salary, but whatever it is, to cover next season, Victor Osimhen must get a new team because he no longer has a place at Napoli.
As far as I remember Victor Osimhen has no problem with Conte, Victor Osimhen himself has a problem with Napoli so Victor Osimhen is no longer comfortable with Napoli. How could Conte have a problem with Victor Osimhen, when before Conte came to Napoli, Victor Osimhen's relationship with Napoli was no longer harmonious. And as far as I remember, Conte was actually very helped if Victor Osimhen was in Napoli, especially if he duetted with Lukaku, it's just that Victor Osimhen is no longer comfortable in Napoli, so Victor Osimhen was loaned to Galatasaray and currently there is a big team that wants to have his services, Napoli seems to want to make it difficult for Victor Osimhen to leave because they sell at a high price.
If I'm not mistaken, Victor Osimhen's relationship with Napoli returned to harmony when Napoli uploaded a video that should not have been uploaded on their Official Tiktok. The video contained mockery of Osimhen, so this is what made Osimhen delete several of his posts with Napoli on Instagram and he sued Napoli. Correct me if I'm wrong.
