I guess I can make a comment about him now when I watched him a bit. He looks like a very good defender who, with a reason, still looks unconfident.
That said I'd like us to buy this guy. He seems very good defensively and wins many one-on-one situations while he's strong as hell and good in the air. Price is laughable and our scout(s) deserve credit for this guy without a debt. But I'd like us to use him in CB rotation with Chiellini and Bonucci. I know he's doing well at the moment as a RB but it's not his position and I don't think I'd settle him there. I'm not a fan of defense based full backs and I see him as one, cause I don't think he can improve in attack much.
