If Osimhen were so in demand, then some team would have bought him long ago, but he continues to play in Napoli, and all his possible transfers end only in rumors. Sooner or later PSG will win the Champions League, and Ligue 1 remains one of the top leagues that provides many opportunities for the player. Mbappe, by the way, came to PSG from Monaco, and now he is a Real Madrid player, in my opinion this is a very good career development, and it didn’t hurt that he started in Ligue 1.
Osimhen previously played for Lille before Napoli bought him for 60 million euros after he performed quite impressively during his season at Lille, so It's surprising that Osimhen market value has also increased rapidly at this time, of course, Osimhen attracted the attention of many big clubs when he was able to help Napoli win the Scudetto last season, but at that time, along with a new contract extension, Napoli fenced him off with a fairly high release clause and making many teams choose to withdraw from recruiting him, previously PSG was reportedly very interested in bringing in Osimhen as a replacement for Mbappe but for some reason now it seems like PSG is not doing anything to realize their current interest.
The decline in Osimhen performance occurred while he was injured when helping Nigeria in the African Cup last season, but even so when he recovered and return to the team towards the middle of this season he was actually able to make Napoli improve again, In my opinion, Osimhen has made a big contribution to the team that has him, so PSG should be able to consider him as an alternative to become their main striker next season, PSG has a guarantee of qualifying for the UCL every season because they have dominated Ligue 1 so far and of course that is could be a step for Osimhen to become a main star in Ligue 1 , so this will enable him to become a target for other big teams in the future like just like Mbappe is currently.
