David Haye will be going for a knockout when he challenges Nikolay Valuev for the WBA heavyweight title in Germany on Saturday night.

Adam Booth, Haye's trainer, maintains the Londoner, who stands 6ft 3in tall, has enough power to hurt the 7ft 2in Russian.

"Heavyweight boxing should be exciting," Booth said. "David always looks to try to knock someone out. This is going to be no different, it's a strategy we employ to go about landing shots.

"It is the biggest challenge of his career because he [Valuev] is the biggest guy and it's the world heavyweight championship, but as a trainer, the Jean-Marc Mormeck [world cruiserweight title] fight was a big challenge because Mormeck's style was wrong for David so he had to adapt and do different things."

Despite Haye's taunting of the Russian in the build-up to the fight, Booth insists they are not taking the fight lightly.

"We're not underestimating Valuev," he said. "There's an easy, obvious statement to make about Valuev that he's big so he's slow. But he's actually not that slow, if you look at the tapes of [him using] his left hand. And he's very effective at going 12 rounds.

"Although he's even admitted himself he is still learning to box, he's only got to be a certain percentage of what other fighters have to be because he's got those attributes of his height and his weight to carry him along.

"So we have to look at what he does best, not what he does worst, and then have the answers for that."
