Vitali Klitschko will not be running scared of Lennox Lewis when the pair clash in Los Angeles next Saturday night.
The 6ft 8ins Klitschko’s fellow big men Michael Grant and Andrew Golota were both flattened instantly by Lewis’ heavy fists.
But Klitschko insists there is no reason for caution against the man whose WBC and IBO heavyweight titles he seeks to claim.
Klitschko said: “We are not talking about a God here. We are all human beings. Everybody has their strengths and weaknesses.
"I heard Lewis say he is going to destroy me and knock me out in the first five rounds. People say I am not strong enough or in the champion’s league. But I don’t care what people say.”
Klitschko has been taking notes from the legendary German former world heavyweight champion Max Schmeling.
Schmeling, now 98, overcame even greater odds to win the crown from the great Joe Louis in 1936.
Klitschko is based in Germany and went to visit his hero Schmeling last year.
He said: “Max fought Joe Louis and he is my idol. When you meet this guy you can just feel the history. He said to me that you have to be focused and concentrate.
“He told me this is an interesting time in my life because I am active. He said he remembered when he was a sportsman and it was a great time.”
