Dereck Chisora says that he is in no doubt that he will beat the 'king' Vitali Klitschko when the pair meet in Munich this weekend.
The Londoner goes into the fight as a massive underdog against the giant Ukrainian, who hasn't lost since being stopped on cuts against Chisora's compatriot Lennox Lewis almost a decade ago.
The 28-year-old was due to fight his opponent's brother, Wladimir, in 2010 but the fight was cancelled after Klitschko junior had to pull out due to an abdominal tear.
However, he has once again got his chance to fight one of the sport's big names and was reportedly hand-picked to face the Ukrainian, despite losing his last two fights, firstly against Tyson Fury and then somewhat controversially against Robert Helenius.
However, the defeats have done nothing to deter the Londoner, who is known for his confident outlook and believes that his all-action style will see him defeat the world champion.
"Everyone is saying that it will be the toughest test of my career but that's just because he has been on the throne for such a long time," the Finchley fighter told Sky Sports. "Maybe this will be the toughest test of his career. It's going to be amazing whatever happens. It will be a great fight, the public will love it.
"A lot of people have tried to do it but they don't have the swagger and the passion to go in there and do the business but I have got it."
