His calmness with the ball at his feet & accuracy of his passing is what's impressed me most. He was hitting first time passes through very narrow gaps between Napoli forwards today time & again with no sign of hesitation or doubt in himself.
He'll get it wrong eventually, but you can see why we play that way & how nice it is to have a keeper comfortable at doing it.
Add to that he's such a front footed keeper & he seems perfectly fit for our style.
