Tyson Fury accused Deontay Wilder of looking for a way out of Saturday's WBC heavyweight title fight after the two had to be separated at the conclusion of a heated press conference.

The 30-year-old Fury remained relaxed throughout as, similarly to when he dressed as Batman to promote his fight with the equally-bemused Wladimir Klitschko, he got to his feet and goaded the champion.

Wilder, uncharacteristically, became increasingly angry until his aggressive confrontation with a then-smiling Fury.

The two fighters' entourages became involved as shoves were exchanged and the challenger removed his shirt.

There was little question that Fury had consistently remained the more composed of the two, but he later insisted Wilder was attempting to provoke him to throw a punch that could have left Saturday's fight in jeopardy.

Wilder remains undefeated in his 40 fights as a professional but Fury, at Los Angeles' Staples Centre, will represent his most challenging opponent, and he said: "I believe Wilder wanted me to aim the left hook so that the fight would be cancelled.

"He wanted to trick me into hitting him so that he could get out of the fight. I'm not going to make that mistake; I'm not going to lose my purse.

"He knows he can't win and it's clear for everyone to see now. He's a very nervous character and by the looks of it he doesn't want to fight. He talks a good game but he talks nonsense really.

"He wanted me to get a massive fine but I'm not that stupid. He's rattled and he knows he's getting an a*** kicking."

"Wilder's nervous; he felt he needed to scream and shout and make threats.

"We're fighting men but he had his big team there.

"We're not afraid of anyone, if you want to fight on the street or the stage that's fine, but we're here to do a job for sport and be professional."

That professionalism will be evident in Fury's corner on Saturday night.

The great Freddie Roach has helped Fury and his trainer Ben Davison develop their game plan for his battle for world domination with Wilder.

Fury's inexperienced trainer Davison will be joined in the corner by the respected Roach, head of the Wild Card gym, and Ricky Hatton.

Credited with transforming Manny Pacquiao into one of the finest fighters in history, Roach has long been recognised as the world's leading trainer, having had an illustrious career in which he also worked with Wladimir Klitschko and Mike Tyson.

Roach's tactics, incidentally, were also significant when Pacquiao inflicted the most devastating defeat of Hatton's career in 2009, and it is only since Fury's recent move to Wild Card from Big Bear in California that his approach has been discussed in greater depth.

Discussing his role with the heavyweight, who also previously worked under the late Emmanuel Steward, Roach said: "They didn't really have one [game plan] set.

"It was dependent on Tyson doing things himself; when I came in I said very calmly 'Maybe you might want to try this and that' and it worked out very well.

"Wilder's fought two southpaws and struggled with both of them. Tyson was born left-handed; he's great [as a southpaw]. He maybe should have been a southpaw all along.

"A lot of people think he's not a puncher but he can punch really hard and knock this guy out in the late rounds. I see Tyson by knockout in the late rounds; people think that he can't punch, but he can punch really, really good. I believe I have the better puncher of the two."

The 58-year-old Roach also endorses Davison's abilities, and does so having rarely been reluctant to criticise what he has considered the poor work of other, higher-profile trainers.

"I've watched him on the mitts and so forth," he said. "He's good; he needs to work on some things. He'll ask me questions once in a while, but he's doing a really, really good job.

"He's a very young man [26] – he's younger than I was when I started training. He's impressed me – he's very good. He does a very good job. Game plan and strategy-wise I think he just needed a little more help.

"[There's] nice combinations that he puts together well, and I like that."
