He seems very uncomfortable with our 'short passes from the back' system. When the ball gets passed back to him you sense a level of panic in his reaction. He doesn't seem to be able to play it along the ground in these situations either, instead lifting the ball to the defender he's playing the short ball to, which means the defender has to waste valuable time getting the ball under control, which in turn gives the opposition's strikers extra time to press our defenders.
IMO of course.
