Recap
Chelsea will loan Romelu Lukaku again, this time probably to Napoli.
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.
It only makes sense if Chelsea can win - otherwise Osimhen will only ruin his career, especially if he stays there for long. If he needs to win, it's a mistake to move to Chelsea. He needs to choose another club that can most likely at least win their league and who are decent in the Champions League. It's hard to say exactly which club would suit him and even more so which club would be able to accommodate him, but definitely not Chelsea
