Dereck Chisora has vowed to knock Vitali Klitschko out in eight rounds to claim the WBC heavyweight crown when the pair clash at the Oympiahalle in Munich next month.

The 28-year-old British boxer is looking to bounce back from the disappointment of a controversial points defeat in his European title bout with Robert Helenius in Finland by pulling off a shock victory over the Ukrainian, the three-time world champion.

Chisora - who also lost to Tyson Fury in their British title showdown in July last year - saw his plans to take on IBF, WBO and WBA champion Wladimir Klitschko scuppered by the holder's injury problems, and intends to take his shot at the big time when it finally comes along against the other brother.

"Number eight is my lucky number and Vitali is going down in the eighth round," said Chisora when the pair came head-to-head at a press conference in London on Monday afternoon.

"He just does not know what is coming - I am physically and mentally coming to take what is his and make it mine.

"I hope you are prepared for that.

"I have already said to Vitali 'I hope you don't chicken out like your little brother, just make sure you are there'.

"I just hope you do not come up with excuses, say 'there is a problem with this or that'. I just want to fight."

Chisora added: "Everybody is tired of you and your brother, because you do not bring excitement to the game. They have killed the sport I love.

"It is time for the new king, and that will be me come February 18.

"I have everyone around the world on my side - in China they may not have heard of me, but after I whoop your ass, then they will.

"The time is here. He is the doctor and I am the black plague. I am coming to destroy him in his own back yard."

Promoter Frank Warren is confident there will be no issue with judging in Germany, after Amir Khan had seen his recent bout in America fall foul of some controversial officiating.

"The fight will be under a lot of scrutiny, we will be asking the Boxing Board of Control to have neutral officials," said Warren.

"We have had the last couple of fights with British guys abroad when there has been some controversy.

"The eyes of the world will be on this fight, so I am quite sure that they will ensure the right people are appointed as referees and judges."

Chisora has no problems with fighting overseas - and claims he can thrive on any negative atmosphere.

He said: "I love it. In Helsinki I was the underdog, but the more boos I heard, the more excited I was.

"We will travel anywhere to fight and I am looking forward to fighting in a famous stadium for the biggest prize."
