Nowadays there is talk that Osimhen could be transferred to Chelsea. Napoli could partially fill Osimhen's void with Lukaku. I think such a swap between the two clubs would make sense. Both teams would get what they need in such a deal. Anyway, I don't think Napoli can keep Osimhen any longer. Napoli are a waste of time for Osimhen. He should play for better teams for his career. And Lukaku can have his last big team experience with Napoli. If he doesn't get good stats at Napoli, he will be forced to choose between a salary cut or a move to the Arab leagues.
