His major failing as a defender is positioning, which is a prime requirement for any centreback. He seems solid in the air, confident one on one, but too often caught woefully out of position, after periods of watching the ball not the players around him. Surely it can't be too tricky to teach him to mark properly???? If Del Neri can manage to make de ceglie look half decent, then its definitely possible to make bonucci look truly decent, because he starts off with more in the bank than de ceglie...whose only skills in the past were running and Omen Damien glare...del neri improved him.
