I believe he has the natural athletic abilities to be a top, top defender. With Paolo being part of the club and the Italian art of defending he is in the right place to reach his potential.
28 million in a few seasons will hopefully be one of the bargains of the decade.
there is also this part of his game not being talked about enough. his passing between the lines, breaking the press and resulting in chances
vs Cagliari he had one to Diaz who flicked it to Leao who was on goal. took a heroic intervention from the defender (and Leao not shooting quick enough)
i do remember a similar move that resulted in a goal last season. cant remember which game.
