Osimhen is in a stronger position in the negotiations as he enters the final year of his contract with Napoli next season.In my opinion, Osimhen efforts to join a new club will be successful in the summer transfer market, and Napoli will certainly push for Osimhen to leave in order to profit from his sale rather than lose him for free. Galatasaray will certainly try to extend Osimhen loan, and I don’t think they will be able to meet his release clause of over £50m.
Osimhen has long been linked with a number of Premier League clubs, including Manchester United, Chelsea and Arsenal. PSG could also be in the running for his signature, and I think those clubs would be a better option than staying with Galatasaray or returning to Napoli next season.
Galatasaray will want to keep Osimhen for another season because they will play in the Champions League, and Osimhen is their best scorer now, so they will not want to lose him, but they will not be able to buy him out because the price is still high. And if De Laurentiis is so categorical, then we can expect him to leave as a free agent, although there is still a lot of time before that and they need to either sell him or extend his contract, but I highly doubt it.
Even if Napoli wants to extend Osimhen contract, I don't think the young Man will accept. There's really no willingness from both parties in trying to extend their contract. Napoli is hoping for an outright sale. And I don't think Osimhen would like the idea of continuing playing in the Turkish league next season. He wouldn't have been in the Turkish league if not for the timing of the deal. Osimhen was almost confident he was moving to Chelsea and it was just unfortunate that the move collapsed in the last minute and the transfer window was over and only the loan offer was the only possibility of him playing football this season, when Antonio Conte made it clear to him that he wasn't part of his plan. So if a better offer comes in for Osimhen this summer, he's definitely leaving Galatasaray irrespective of their champions league football next season.
