I know what you mean, that's why I said he looks a little manic above. Rushed and uncomfortable. Always felt Martin Keown was the same. Think they're very similar players in a lot of ways.
He defends the box really well though, really strong in challenges and hard to win an aerial battle against. Quick and agile as well. Would say he's a good reader of the game, maybe not great, but always thought he judges the offside trap really well. Seems to switch off here and there though, but I think that'll improve at Arsenal, and I still think there is big room for improvement in him generally.
