Chisora is undeterred by criticism

Dereck Chisora could not care less about the critics who have already written off his chances of pulling off a shock victory over WBC heavyweight champion Vitali Klitschko.

Chisora lost two of his last three fights, against Tyson Fury and Robert Helenius, but still managed to set up a fight against Klitschko next month, perhaps at the expense of London rival David Haye, who wants to come out of retirement to fight “Dr Ironfist”.

Critics have been lining up to ridicule any hope Chisora has of beating the 40-year-old Ukrainian, who, along with brother Wladimir, has dominated the heavyweight division for the best part of a decade.

But Chisora, who is six inches shorter than his opponent and has a physique which is nowhere near as chiselled, is not concerned that the boxing world is giving him no chance of winning the bout, which will take place in Munich on 18 February.

“I don’t care what people think,” Chisora said. “They are not the ones who are going in to the ring. I am the one who is doing the fighting so I will decide what happens.”

He added: “Vitali has been around a long time. He is the king of the sport but it’s about time that somebody came in who is young and fresh and I am going to whoop his ass.”
