GK
Striker
In my world where we speak English, aye. Whether or not he is slaughtered by stupid people, or people with an agenda like the press, is irrelevant to whether he's fit to play in the sandbox with Gary Medel and Tom Cleverley (who clearly are international class).
Tom Cleverly routinely gets slaughtered by the press and the support. If being called shit every time he plays for England is considered international class then Cattermole is international class. If however international class means more than that then he isn't.
