Tyson Fury believes a match-up with Anthony Joshua is the only fight people want to see and claimed he would win with "one arm tied behind my back".
Joshua is not expected to be short of options following his sensational 11th-round stoppage of Wladimir Klitschko at Wembley on Saturday night, with a potential rematch with the Ukrainian or a meeting with Deontay Wilder both possibilities.
Joshua himself called out Fury in the wake of his Wembley win, with the 'Gypsy King' hitting back, pledging that he would reclaim two of his old titles by inflicting the first professional defeat on the WBA and IBF heavyweight champion.
"Styles do make fights but I am sure I can beat AJ with one arm tied behind my back," Fury said. "I don't even need a warm-up if he wants this.
"I have been out of the ring as long as Klitschko but the difference is I am not 41, I am 28.
"There's only one fight out there, the biggest fight in the world and everyone knows that. It is the heavyweights, it is me and AJ, no one else.
"It is the only one the world wants to see and I am the lineal champion, I am still No.1 in the world. We all saw (his career) had a life and death situation against Klitschko, but Klitschko couldn't land a glove on me."
Fury has not fought since winning a unanimous decision over Klitschko in November 2015. He surrendered the various titles he won in that fight to focus on his mental health problems.
Fury had his licence temporarily revoked by the British Boxing Board of Control and must wait to see if his licence is returned at a hearing next week.
While Fury is keen for the bout, Joshua's promoter Eddie Hearn may have other ideas.
"It will soon be time to go global," Hearn said. "If we do fight Klitschko again it doesn't have to be in the UK. That might suit Madison Square Garden. The reaction from America was massive. Joshua will box next in October or November."
