Notwithstanding Deontay Wilder’s accusations of ‘nervous behaviour’ earlier this month, Tyson Fury looks calm and relaxed in the run up to his bout with the American this Saturday.At his BT Sport’s green screen session, the irrepressible Fury is told to just walk into the camera and roar a little bit.Looking incredulously off camera Fury replies: “Say what?!”“Roaaarrrr!” says the cameraman.“Roar?”“Yeah!”“Are you serious?” asks Fury, before turning to the camera and meowing like a pussycat.Fury will fight Wilder at the Staples Center, Los Angeles, on December 1 in his first proper fight since his comeback, which started in the summer against Sefer Seferi.Following Seferi came Francesco Pianeta, another comfortable night for the Gypsy King.Despite the high stakes, the Gypsy King is showing no nerves and is looking sharp in a flowered white shirt and grey suit.At his lowest, Fury drank 100 pints a week, reaching 28.5 stone to be – in his own words – ‘disfigured for life’.But after losing almost 10 stone, he now looks in better shape than when he won the title against Wladimir Klitschko in 2015, although his camp is clearly not complacent.Speaking to BT Sport, Fury’s trainer Ben Davison said: “He knows that Deontay Wilder is a very good fighter. A very good champion.

“He’s definitely got respect for Deontay Wilder. But, we’ve got a job to do.

“I think he’s the most dangerous fighter in world boxing. He’s a freak of nature.

“Similar to Tyson but they’ve both got different attributes; being freak of natures. 

“He’s 6’7”, weighs about 15.5 stone, he’s lightning quick, punches like a horse kicking, he’s got a long reach.

“You know, he’s a very, very dangerous man, and, I’ve said it before, and I think that this win will be the biggest win in the history of boxing; coming from where Tyson’s come from.

“And I might be biased, but knowing from where Tyson’s come from, I believe this’ll be the biggest win in the history of boxing” he repeated.

Following the bout, Fury has promised £8m of his purse against Wilder to the homeless.
