He is what he is: a reasonable premier league centre back with limitations. It can be temping to look at his fee, but at the time his stock was high, he wasplaying regularly in the Premier league, and it wasn't the craziest fee out there for a well regarded young English player in his position. Maguire and Stones can take a bow on the latter. Honourable mention to Kyle Walker at full back.
Having said that, we have brought better in thst position in recent history. Admittedly a different time with different market dynamics, but Distin, Jagielka, Yobo and I'd even say Heitinga were better players. Be interesting to see their value in today's market.
