Coleman wasn't playing against Bale though. Who, may I add, Hibbo has had in his pocket on more than one occasion.
Hibbo is a full back of the old style, Coleman and Maicon are much closer to what would have been wing backs, as said above, when you don't attack then it's hard to be caught out when your opposition counter.
Coleman and Neville have also both had great games against Bale, one of Coleman's first games was against Bale (albeit in midfield) and he tore him apart, almost single handedly earning us a draw.
You're missing the point anyway. All attacking full backs/ wing backs have the same issue. Baines has had the same issue with Antonio Valencia, it's a property of all attacking full backs, not just Coleman.
