Tyson Fury claims he could beat reigning world heavyweight champion Deontay Wilder with "a hand tied behind my back".
Fury, the former WBA, IBF and WBO champion, is returning to the ring after an absence of more than two years on June 9.
The 29-year-old claims the principle motivation to reignite his career came after some remarks from current WBC holder Wilder.
Speaking at a press conference, Fury said: "Deontay Wilder has given me the ambition to return, he said I couldn't do it. He said Tyson Fury is done. I can have a hand tied behind my back and beat Wilder."
The opponent for Fury's comeback fight is still to be named but he hopes to be back in world title contention within two or three bouts.
By then American Wilder could have faced Britain's Anthony Joshua, who now holds Fury's former titles, in a unification clash.
Fury said: "I'm going to have a couple of warm-up fights then I'll be ready for them. I believe my talent and confidence is enough to beat these guys."
Sky Bet make Fury 4/6 to beat Wilder (11/10) in any fight taking place before the end of the year.
