Is it just me or is he he sometimes wildly out of position, and not just because he is too far forwards; he seems to get dragged into areas he shouldn't be and the lcb or lcm has to move over to cover and we lose our shape.
Often when we are defending in transition I wonder where he is then spot him and think "what the fuck is he doing there?!?"
He seems to be in better position than Aurier is, but that may be that he is faster and smarter so he can get back in position where Aurier seems fine to stay badly out of position without making any effort to get back.
Also could be that with Ben Davies not really leaving the tiny area that he would stay as a LB it is odd to Spurs fans seeing a LB that actually moves around the pitch.
