Haye expects the Kiltschko fight to be a "career-defining" contest

Lennox Lewis has said David Haye's speed and movement could be the deciding factors in his heavyweight clash with Wladimir Klitschko.

Lewis told Sportsweek on BBC Radio 5 live that Klitschko will start the 2 July bout with several advantages.
But the former world champion added that Haye could triumph if he repeats the tactics he used

"He fought a perfect fight, he kept moving, he stayed elusive," said Lewis.
"He has the speed and the weight in his arms and any shot he hits Klitschko with will be a shocking blow.

"Klitschko has the bigger advantages but if David is able to stay with his game plan and move and throw combinations he should do very well."
Lewis added that it is crucial for Haye to prevent Klitschko, 35, from using his weight advantage in the bout at Hamburg's Imtech Arena.
"His [Klitschko's] strength is his size, his reach and his weight," stated Lewis. "He has all those advantages and on paper he is the one they will pick to win because he is a natural heavyweight.
"Haye is light but he can use it to his advantage if he can stay away from him.
"But if they get into a clinch and Klitschko puts his weight on David it may sap some of David's energy."
Haye enjoyed success as a cruiserweight in the earlier part of his career and is still relatively light for a top-ranked heavyweight
