British boxer Dereck Chisora has said that he will knock out WBC heavyweight champion Vitali Klitschko in the eighth round of their title fight on Saturday.
The Zimbabwe-born fighter meets the 40-year-old Ukrainian, who is brother of David Haye's conquerer Wladimir, in Frankfurt on Saturday.
Chisora, 28, goes into the fight as underdog but is sure of victory, although he was complimentary about his opponent.
"Vitali has been around a long time. He's the king of the sport but it is time someone came in who is young and fresh," said Chisora.
"It is the end for Vitali, I promise you. I will end the Klitschko reign and cause a massive upset in my magic eighth round. It will be felt around the world.
"A lot of people have tried to do it but they do not have the swagger and the passion to go in there and do the business. I have got it."
Vitali has won 43 of his 45 professional fights, knocking out his opponent in 40 of those victories.
