Tyson Fury revisited his greatest victory when he came face-to-face with Deontay Wilder at the final press conference for Saturday's WBC heavyweight title fight at the Staples Center in Los Angeles.
It is three years to the day since Fury produced major upset by travelling to Germany to outbox Wladimir Klitschko, who had been undefeated for 11 years.
Morecambe's former heavyweight champion is hoping for more of that kind of magic this weekend and he has vowed to stop America's champion.
Fury said: "It's three years since I went to Dusseldorf and beat Klitschko.
"On Saturday 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 by me."
Wilder responded by dismissing Fury as having had "his time".
After beating Klitschko, the 30-year-old remained inactive for over two-and-a-half-years as he struggled with mental health issues and gained weight until reaching an estimated 27 stones,
"This is a moment I've been waiting for my entire career; this is my time," the 33-year-old said.
"Fury had his - when he beat Klitschko that was his window to do whatever he had to do.
"How he took upon his responsibilities as a champion was up to him. But now it's my time. I've sat patiently, waiting.
"I will knock Tyson Fury out. They say I'm the puncher and he's the boxer, but the same thing was said when I beat (Bermane) Stiverne.
"I'm going to show you how well I can box. He will go down."
Their press conference concluded with a heated exchange in which both fighters had to be separated as they shouted each other, before their angry entourages threatened to lose control.
