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.
According to rumors that I read, Chelsea has agreed to exchange 2 star players and a certain amount of money to recruit Oshimen. It is known that the price tag for Napoli is quite high and Chelsea is negotiating by donating 2 of their players and the players that Chelsea sacrificed are Casadei and Lukaku.
I think this is a quite profitable exchange for Napoli because it gets 2 players at once and a transfer fee, at least Antonio Conte has several options to use that players.
I think Lukaku can replace Oshimen's role on the front line, Lukaku has experienced Antonio Conte's coaching system and he is quite suited to it. The coach also wants to reunite with this player so I think their chemistry is still going quite well and it is very likely that Lukaku can play a good role Next season.
