He's an interesting player. From his comps it's easy to see how talented he is, and very difficult to know how effective he'd be in this league.
A lot of that stuff is against weaker keepers and slower opposition than he'd face weekly in England. He does look a bit like Martinelli which means he might not be an upgrade anywhere.
He's a good shout, and his former manager De Zerbi (who seems like a clever guy) evidently rates him, but given he's not proven in a top league, I'd be a bit upset if we parted with more than £50m to sign him.
