Dereck Chisora has compared himself to herpes ahead of his British title fight against Dillian Whyte on December 10 in Manchester. The veteran heavyweight said that like the infection, he just keeps popping "back up".

Chisora, 32, has lost six of his 32 fights as a professional and was widely written off after he was defeated by Kubrat Pulev in Hamburg in May. But Chisora has quickly bounced back and vowed to knockout his long-time rival at the Manchester Arena next month.

"It's a big day on 10 December, for me I've lost six fights, people write me off but you can't write me off," the heavyweight contender told IBTimes UK at a pre-fight press conference. "I'm like herpes – one minute I'm gone, then one minute I pop back up. So it's like you have to see the doctor and get a pill but then suddenly I pop back up.

"In terms of my opponent, there's nothing much I'm scared of, he doesn't bring much to the table. He's got a good selection of punches but he hasn't got a power punch so I'm looking forward to the fight. All I see is Dillian on the canvas."

Whyte, on the other hand, has dismissed Chisora's pre-fight boasts and ridiculed his performance against Pulev, saying he showed "no heart" en route to a split decision loss. He also promised to retire Chisora by defeating his rival in Manchester, predicting his opponent will become a dustbin man after their fight.

"Dereck (Chisora) is deluded as everyone knows," Whyte said. "He thought he could go to Germany and knock out (Kubrat) Pulev. He showed no aggression and no heart in that fight. All he was doing is coming forward and getting hit in the face all night long.

"The same thing is going to happen again. In this fight I'm definitely looking to knock this guy out. He's a tough guy, he's game but I think his time is gone. I'm looking forward to seeing him on the Thursday, collecting the bins outside my neighbourhood after I put this beat down on him. I'm going to make an end to Dereck's career."
