Trainer Emanuel Steward feels that it's necessary for WBA champion David Haye to take risks in his July 2 unification bout with WBO/IBO/IBF heavyweight champion Wladimir Klitschko. Steward, who trains Klitschko, expects Haye to come out swinging with the hope of landing something big to Wladimir's chin. Steward respects Haye and considers the bout a "must-win" situation because a loss will always hang over Klitschko's head and overshadow his past accomplishments.

"David is as quick as Sugar Ray Leonard and hits as hard as Mike Tyson. We respect him more than any of Wladimir’s previous opponents. This is a must-win fight for Wladimir because this is the fight which will define his career. If he loses all his accomplishments so far will not be remembered," Steward told Jeff Powell of Daily Mail.

"So, while I always have  confidence in my fighters, this time I also have anxieties. David also has the mindset of a  champion. Fighters are made inside themselves. He has the arrogance and belief of a winner. Then I remember that he has not yet fought a real live heavyweight. Audley Harrison? Please. He cannot hope to out-box Wladimir. He will have to gamble. Come out aggressive and hope to catch my man."
