I get into the ring with a 'Ricky Fatton' T-shirt on and I've got a picture of me and Bernard Manning in our underpants on the wall of my gym. He's saying all these things trying to get under my skin and he's barking up the wrong tree. With him calling me out, I don't look across the ring and say I'm going to smash his face in more than anyone else.

"I think he's a very insecure man. He has four big minders around him and they are in his ears constantly. I think he needs reassurance and loads of 'yes' men around him.
