Thing is he's backed himself into a corner here. He's saying stuff like "we're in a real fight there" and "I've got a massive challenge on". Unlike Villa where, league wise, he was getting good positions and then decided to fuck off because, behind the scenes, he wasn't given more money (I'm sure Brummie will correct me if I'm wrong there!)
He has no place to hide and I don't think he'll get away with it if he does just down tools and leave. Unlucky Marty.
