Difference? Bannan didn't try to con the ref, he got his rightful punishment, and he knew what he was going to get.
Young got a penalty and last week, a pen and a red card to a Derry who hadn't done anything, as "reward" for his cheating. That's the bloody difference.
And of course the defender would stick his leg slightly out. Point being, there was absolutely nothing forcing Young into running into him, he changed direction slightly instead of going for the ball and having a go. It's cheating, why not just leave it at that? Not try to cover it up. Every defender in the world would have stuck his leg out slightly, it's a reflex. It's not as he tried to trip Young.
And yes, he's always been at it at Villa as well.
