His obsession with playing for England is part of his problem. He should concentrate on his club team first. Best thing for him would be to get dropped completely from the england set up, not that it will happen.
He has zero humility, which is also a massive problem. Yes you want golies to be confident, but it isnt confidence with him, it's absolute arrogance, and a failure to 'get' what everyone else sees. Sure, he's likely as thick as two short (armed) planks, but my god, someone needs to take a hold of him and tell him to tone down his horrendous attitude. The lad needs media training as much as he needs goalie training.
