I remember when he signed for us there was an interview with one of his youth coaches at Newcastle who, whilst praising him, mentioned in passing that he's always had this strange habit of landing, after heading, on one ankle (while the other leg lands on the balls of the foot), which had caused him a few back, knee and hamstring problems. Even more strangely no one had coached him effectively to land on both feet properly. So I wonder now whether he's going to remain one of those players who suffers from injury niggles. Anyway, at top form he's a terrifying player, so it's a huge pity how inconsistent he's been.
