Tyson Fury vs Dereck Chisora: Fury needs to be punished in the ring for his foul-mouthed rants, claims Chisora

Dereck Chisora insists Tyson Fury deserves to punished for his foul-mouthed outbursts in a press conference but believes only defeat in the ring will change his opponent's behaviour.

Fury was given a misconduct charge and fined £15,000 by the British Boxing Board of Control after he directed a number of expletive-ridden insults towards Chisora and journalists in June.

The 26-year-old mocked the board's charge at a media event on Monday, however, by wearing tape across his mouth with 'BBB of C' written across it and refusing to speak.

Chisora takes on Fury at London's ExCel on November 29, looking to avenge his unanimous loss on points in 2011.

"The last straw for me is when a veteran reporter - a guy who has been in the game for so many years - asks why he is swearing so much and he tells him to 'F-off' and stuff like that," Chisora said of Tyson's behaviour.

"You can't talk to people like that. You can't do that.

"For him, £15,000? He deserved to pay that for what he did to the man there, swearing at him.

"You can't do that, the guy has grandkids. You can go too far selling a fight. It's like me telling you guys to 'F-off'. It's not cool is it?"

Chisora's own disciplinary record is far from spotless.

In 2009, the 30-year-old was handed a £2,500 fine and a four-month ban for biting Paul Butlin in the ring while three years later he received an indefinite suspension from the World Boxing Council for various misdemeanours surrounding a fight with Vitali Klitschko.

Chisora claims anger-management classes have changed his behaviour for good but believes Fury, who is unbeaten in 22 fights, can only be remedied in the ring.

"But I think with time people get bored with that character.

"When he loses a fight he'll be completely different, I'm sure of that. When he loses, he'll be more humble."

Chisora was forced to pull out of the initial bout in July with a fractured hand and Fury subsequently arranged a match with Russian Alexander Ustinov before withdrawing 48 hours later when his uncle Hughie fell ill.

Chisora has been sparring with Ustinov and says he was relieved the replacement fight fell through.

"I didn't want him to fight Tyson because that could've killed this fight if Tyson had got beaten," Chisora said.

"When Frank Warren came up with Ustinov's name, I told him not to take the fight, he asked me why and I said: 'Because he will knock Tyson out."'

Fury and Chisora are battling for the vacant British and European heavyweight crowns as well as the right to fight reigning champion Wladimir Klitschko for the WBO title.

"It'll be a tear-up, it's not going to be a tinkee-winkee dance," Chisora said.

"I'm convinced I'll knock Tyson out because he's lost so much weight and so much power in his legs. He's draining himself right now.

"He thinks the more weight he loses, the fitter he gets but it'll catch up with him.

"When we fought the first time - that was the right shape for him to be in, I don't think he wants to come in lighter for this fight."

Chisora added: "I understand most people are writing me off - it's good to be the underdog.

"I've seen what people are saying and people's tweets and that's fine, I like to be the underdog, it motivates me, I enjoy it."
