Walker is a quality player and he has been unfortunate this season and he has been injured on a couple of occasions. I think DA through him in the deep end playing at centre half, where his best position arguably is in midfield, with Ray, Nolan, Raynes and NG up for the centre half position its difficult for him to stake a place at centre half, although I would probably place him ahead of Raynes. In midfield its even more difficult but I think he is decent enough to hold his own in there, personally with the depth we have there and with the signing of Jones I don't see a place for Green and Walker is more of a ball winner and we need someone who is not scared to mix it up in the middle and is comfortable on the ball, some will disagree, but its down to DA to decide.
