Tyson Fury has claimed that Wladimir Klitschko will retire before he gets the chance to fight for the Ukrainian's four heavyweight world titles.
The 24-year-old takes on Steve Cunningham at Madison Square Garden on April 20 and a victory would take him another step closer to a shot at the IBF title.
He has been eagerly talking up a bout with the reigning IBF, WBA, WBO and IBO champion, but believes that the 36-year-old is avoiding him.
"I've got one thing to say to Wladimir Klitschko - you are a pussio son," Fury told iFilm London.
"When you grow a pair of balls come and fight me and I'll relieve you of all them belts. And I'll leave that glass chin of yours in shatters all over that ring.
"Obviously that's never going to happen because he's never going to fight me. [He's] going to retire before [he fights] me."
Klitschko announced this week that his next opponent will be Francesco Pianeta.
