I've seen this lad a number of times. I'd say good in the air, strong tackler, and quicker than Stearman and Jake Wright. His limitations are his composure on the ball and his ball carrying ability. I see him as a capable centre half in the centre of a back three, or as a centre back in a back four (next to Stearman).The key qualities that are required at the centre of a back three are: good ability in the air, good reading of the game, and excellent positional sense. The only centre back we have who reads the game well and is an option at the centre of the back three is Jake Wright. Wright has many other limitations compared to say Stearman and Basham - reading the game is not one of them.I think for the age of the player and the fee paid, the Blades have done very well here. Centre backs are the new strikers in terms of scarcity and inflated transfer fees.He still has development in him, and could leave for a huge sum in the future. My number one realistic target, just like Henderson.
