Mike Tyson insists size doesn't matter in the ring ahead of David Haye's showdown with giant Russian Nikolai Valuev.

The British heavyweight is hoping to come away from Nuremburg with the WBA belt despite conceding almost 10 inches in height to his opponent.
However, during an interview with Sky News, Tyson feels the outcome would come down to each fighter's state of mind, rather than any physiological advantage.
And the former champion, who has arrived in the United Kingdom ahead of a promotional tour, feels Haye can be victorious - provided he believes that Valuev is beatable.
