It wouldn't surprise me if Caldwell was involved in this story to be honest. He has a reputation for being a bit of a media bitch.
Nothing in it im sure. I doubt whether McCarthy has even been contemplating his International future in recent times. There are no games coming up (apart from a March friendly which has no impact on the decision) and he has just broken in to the Wigan first team which Im sure is where all his focus is on at present.
