Without having to move to another team, Victor Osimhen's selling price will still be high, because the coach will probably look at Victor Osimhen's skills, not which team he belongs to. His match history is also very good so it is impossible for his selling price to drop. So far, Napoli still really needs Victor Osimhen so it is impossible for Napoli to let him go at a very cheap price. His young age also adds value to Victor Osimhen's price because he is one of the best attacking players with a variety of experience.
Osimhen's performance, which has decreased slightly, indirectly reduces the value he has because however, currently Osimhen's value has decreased by around 20 million, whereas last season Osimhen's value was 130 million and now it is 110 million, which is an indirect value. His performance decreased because his performance was not very good this season.
If in the end things like this continue to happen then it is not impossible that sooner or later the value will decrease drastically where the performance is not improved properly, then indirectly the value will be affected and this performance problem will improve again if there is a good relationship between Napoli and Osimhen but for now this is difficult because some of the tension that has occurred between Napoli and Osimhen this season indicates that their relationship is not very good which could make their performance adjust.
More than 100 million is still quite big for Osimhen and now it remains to be seen which clubs are interested in signing Osimhen in a summer transfer.
