We were linked with him before Napoli signed him. Diawara is another on their books that has a bright future too isn't he?
Didn't know we was linked to him, and tbh, I doubt we will get him. He will either stay with Napoli or go to Barca, Real, City or Chelsea imo.
As for Diawara, I don't really watch Napoli when Jorginho isn't playing, but the little I have seen of him when he comes on, he does look good (probably would be an improvement over the players we have in the deepest midfield role), but you can also see a drop in level with Napoli being weaker in possession play.
