I think it's also in part because Wigan knows how much Roberto likes McCarthy. And, at the risk of sounding overly simplistic, we're the only ones rumored to be in the bidding for him as far as I can tell. If he was worth the 13M-15M Pounds wouldn't other teams be rumored to be in on him in at least a casual manner? Why are we the only ones? Feels like they're more than content to keep him and are therefore playing their hand against Roberto's.
