I agree Chesney's alright but alright doesn't win you anything. We need to be aiming for better than alright.
I just have a hunch with Ches that he's one of these characters that needs to be pushed. He seems to always be clowning around (I know all goalkeepers are supposed to be crazy). If an ageing Lehmann was our number two then Ches would have pushed on and would be a world beater by now.
