So did PIG. All keepers make errors, the ones who make less are playing top flight. As far as a No 2 in the Championship goes, I would say with have a sound one.
Good experienced back up who is a key member of the changing room apparently. When our No 1 comes in (and he will) he will sit on the bench without any toy throwing and help develop Walton (who I would personally loan to a southern league 2 club to get some much needed experience).
