He already has a new club or what is the idea behind your post? The whole thing has been sorted out and he extended his contract with Napoli until 2026, then he went to Galatasaray and the deal is that they take care of his salary, which means Napoli has nothing to do with it for the next 11 months. Afterwards the idea is that if he decides to leave the club, Napoli would still be able to cash in a substantial amount of money in transfer fees.
But there is another clause that allows him to leave Galatasaray in winter and there is a set fee that on the one hand Galatasaray would be getting and then there is a set fee as far as I know, which ensures that Napoli would be making a lot of money. It was a last second win win situation created.
If he plays well, I think there is a little chance that he would leave Galatasaray around Christmas already.
Victor Osimhen is one of the best striker in current soccer world, and he deserves respect for his quality and skills as well but sadly due to some mess-up in Napoli we have problems for both parties which ended on wrong way as we have no top club jumps for buying and at the end he is now at the Galatasaray for 1 season loan deal most chances he will be complete this deal and then in 2025 we will have good end of his current era at the Napoli.
Now recently we are having some updates about his future as he is extended his contract with Napoli, and they cut-price tag which is good both parties now in coming season we can have some better response from few clubs about his possible transfer even currently many rumours are around about his winter possible transfer which is not clear but most chances now he will be complete his deal and then leave for any other better option.
