Tyson Fury and Deontay Wilder's press conference descended into chaos when the heavyweights faced off in Los Angeles on Wednesday.
The pair, who will fight on Saturday for the WBC Heavyweight crown, became embroiled in a melee before their teams ushered them from the stage. Fury removed his shirt as the fighters exchanged insults.
Fury said: "He's definitely rattled; he's nervous and he's on edge. I'm going to make him look like the clown he is. He looked very nervous, I did not instigate that, he did. He was shouting, screaming and everything. That was exciting, was not it? He knows he can not outbox me, so he was trying to get personal. He's trying to psyche himself up for the fight but I'm relaxed, I'm a born fighter. "
The former world champion reminded Wilder of his greatest victory as they came face to face at the final press conference at the Staples Center. It was three years since the Fury produced a significant upset when he outboxed Wladimir Klitschko, who had been undefeated for 11 years.
Fury said: "It's three years since I went to Düsseldorf and kicked Klitschko's arse all over the place.
"I'm going to punch [Wilder’s] face in for him. I've heard a lot of people say 'Wilder by knockout or Fury on points', but I'm telling you now, Wilder's going to get knocked out. "
Wilder responded by dismissing Fury as having had "his time". After Beating Klitschko, the 30-year-old remained inactive for more than two and a half years as he struggled with mental health problems and gained weight until reaching an estimated 27st, something that could still undermine him on Saturday.
"This is a moment I've been waiting for my whole career; this is my time, "Wilder said. "Fury had his – when he beat Klitschko that was his window to do whatever he had to do. How he took up his responsibilities as a champion was up to him. But now it's my time. I'm sitting patiently, waiting.
"I will knock Tyson Fury out. They say I'm the puncher and he's the boxer but I beat when the same thing was said [Bermane] Stiverne. I'm going to show you how well I can box. He will go down. "
Fury was keen to underline his performance and his "mission" to represent the vulnerable people.
"I stand as more than a champion – an ambassador for mental health. I am the people's champion, "he said. "I'm not just for me, I have millions of people that look up to me."
