Tyson Fury has launched a withering attack on both Wladimir Klitschko and Vitali Klitschko.
Wladimir currently holds the WBA, IBF, Ring and WBO heavyweight titles, while his brother is the WBC champion.
However, despite the Ukrainian duo holding all the titles in the division, Fury has unleashed a tirade against the pair, saying that neither man wants to fight him.
"[Wladimir is] A b****. He doesn't want to fight back and he doesn't want to fight anybody dangerous. So that, to me, is a b****," the Daily Mail quotes Fury as saying.
"If they put Vitali in the same ring with me I would take his heart out and feed it to him. But I've got no appetite for beating up old men. At 42 you're a pensioner, not a heavyweight boxer. The Klitschkos know that age waits for nobody."
The Manchester-born fighter also reserved some words of contempt for David Haye, claiming that he holds the Londoner in even lower esteem than the Klitschko brothers.
"If Wladimir is a b**** then what does that make Haye? What more can I say about him than he has humiliated himself already.
"The guy goes into a world heavyweight title fight saying he's going to knock out this Klitschko, then he runs away. Well, that's worse than being a b****. That's a pathetic loser."
The 24-year-old Fury has a record of 20-0 with 14 wins coming by way of knockout.
