Dereck Chisora is confident he can beat WBC champion Vitali Klitschko
Dereck Chisora believes he can silence his critics when he takes on WBC heavyweight champion Vitali Klitschko.
The 28-year-old has been written off by critics and pundits but says he can get a result in Munich on 18 February.
The Zimbabwean-born fighter has lost two of his last three fights but is still brimming with confidence.
"I don't care what people think, they are not the ones going into the ring," he said. "I am doing the fighting so I will decide what happens."
Chisora, at 6ft, stands six inches shorter than his opponent, who has an 88.89% knockout rate.
Ukrainian Klitschko, 40, is yet to be knocked down in any professional fight, or lose on points.
His only two defeats to date have come courtesy of a shoulder injury during a fight and a deep cut above his eye, resulting in a technical knock-out against Lennox Lewis in 2003
"A lot of people have tried to stop him but they don't have the swagger and the passion to go in there and do the business that I have got," said Chisora at his gym in north London.
"I am not scared. That's why I am going to be successful.
"Everyone is saying it's going to be the biggest fight of my career but that's just because he has been on the throne for such a long time.
"Maybe this will be the toughest test of his career."
