Tyson Fury told Ringside a meeting between him and David Haye would be the biggest fight in Britain ever.
Talk of a blockbuster bout has been getting louder in recent days and promoter Eddie Hearn admitted on Thursday that a clash on September 28 in Manchester was nearly finalised.
Fury, whose last outing was a stunning knock-down of American Steve Cunningham in New York in April, said negotiations were "very close" and told the Sky Sports boxing show that stepping into the ring with Haye was the only option firing him up.
"It's the only fight that would ever make sense for Tyson Fury right now," the unbeaten 25-year-old said.
"I've fought the two Americans, the top Americans, and I've been to New York and fought at Madison Square Garden and now I'm ready to take over the division.
"If this fight does happen then I think this fight will be the biggest fight ever to enter a British boxing ring. The British fight fans and the British public are in for a real real treat.
"When it comes to talking there's no one better than me and David Haye for entertainment and excitement. It's a 50-50 fight, we're all-action fighters and when we do get in there it will be a war, like the words will be."
Haye, 32, was forced to withdraw from a June date with Manuel Charr because of a hand injury sustained in training and last entered the ring in July 2012 when he stopped Dereck Chisora in the fifth.
"As far as I'm concerned I'm the No 1 heavyweight in the UK," added Fury who has fought 21 times with no losses and 15 KOs.
"David Haye is a pretender and a celebrity who likes to live a celebrity's lifestyle. But I'm an active fighter and it's a man who's had two fights in two years against a man who's had lots of fights in two years. I've been busy against world class fighters and it will tell on the night."
When asked if Fury was considering alternatives, if the Haye clash fell through, Fury said: "There's nobody else if the Haye fight doesn't happen. The only fight that might make sense is Vitali and Wladimir Klitschko.
"I don't see anybody else to fight. And actually, I don't think either of the Klitschkos would be as big as me and David Haye. It's the biggest fight in boxing across all divisions and I can't think of any other fight that anybody would want to see.
"There's only one heavyweight in the world and that's me. I'm the one to beat and nobody in the world can compete with me and I'm going to prove that. I've been an underdog many times and I'm ready to take on anybody. I do believe in my heart of hearts that the Klitschkos won't fight me."
Having been knocked down by Cunningham before bouncing back to stun the American two months ago, the Manchester-born Fury rejected any notion that he would be picked off by the powerful Haye.
"The Cunningham fight was up and down," he said. "I was taking silly shots but I'm there to entertain and I was very happy with the performance. The way to beat Tyson Fury is to nail him to the canvas and if you can't do that then I'm going to get up and do you in.
"I don't know how to lose, where as Haye's been beaten. If Carl Thompson (the 40-year-old beat Haye in 2004) can do that to him then wait until he gets in the ring with me."
