He is a strong fighter. A great fighter, his record speaks for itself. I mean everybody who gets in there (with Vitali) basically gets knocked out, probably the toughest fight I have ever had. I think we devised a game plan to be mentally and physically ready to show you all something that you have never seen before. So if you miss this one, you will certainly miss the best fight of my career and I have had some good fights.
