Yes, there is no confirmation yet on Osimhen. He is most likely to stay at Napoli until 2025 when his current contract will end. Although I learnt that PSG is in talks to try and negotiate with Osimhen I doubt that it will yield any positive results as Napoli will still want to hang on to him. I heard a rumor; I call it a rumor because I am yet to confirm that a Saudi Club wants him. If this is true, if he goes there his budding career will be ruined forever. As he will be playing for the money not for the growth and development. His shelf will be lacking in championship titles, and awards and medals. He may even regret it.
What is currently happening is that Al Hilal continues to tempt Osimhen with a large salary so that he goes to the SPL, but it will not be that easy even though their offer is above the average salary of other players, he is not an old player even developing this season with Napoli so it would be very natural for many other clubs to target his services to buy at any price.
PSG currently has no offer with Osimhen, PSG has recruited Dembele from Barcelona maybe this is an option to replace Mbappe later, now back to Osimhen he has spoken before that being at Napoli is very happy, meaning there is a possibility that he will still survive until the contract expires.
