Tyson Fury says he will deal with unified heavyweight champion Anthony Joshua “like a cat playing with a ball of wool” when he returns to boxing.
Fury, 28, has dealt with depression and lost his boxing licence since beating Wladimir Klitschko in November 2015.
In a wide-ranging interview, Fury said he will shed eight stone in weight and remove the “fraud from the division”.
“Joshua is a big man with a puncher’s chance and has no footwork, no speed or stamina,” Fury told BBC 5 live boxing.
“He is what you call a boxer’s dream. I’ve had 18 months out and ballooned up to 26 stone. I could come back with no comeback fights and still box rings around that body builder.”
