Vitali will know he has been in a fight and it will be a fight and not a boring dance. "Hes 40, hes slow and I know that I can pull off the shock hes only a man like me and Ive more desire.

But Chisora, who owns a three-wheeler from Only Fools and Horses, a London taxi and a Smart car, is crazy enough to pull it off.
