Alfie Gilchrist was already on loan at Sheffield United. I don't think he will make the Chelsea squad, they will loan him out again this year or sell him.

Brahim Diaz is a successful player, he can play as a starter anywhere he wants, but he preferred to fight for his place at Real Madrid.

I also read about Darwin Nunez today, I think he is a good signing for Napoli. But apart from Nunez, the name of Lorenzo Lucca from Udinese is also mentioned. He scored 12 goals in the league last season. They can choose him as a pivot striker. He's much more affordable and he's young and promising.
