The outspoken Fury is backing IBF belt holder Charles Martin to do a number on Joshua when the pair meet at the O2 Arena in London on April 9.
Even going a step further than that, Fury has branded Joshua as a ‘useless bodybuilder’ and says American Martin will knock him out when they meet.
“Joshua can’t box. No, he doesn’t have a jab. Yes, his movement is terrible and he’s wide open with no idea how to defend himself,” Fury told The Daily Mail.
“His footwork is hopeless. The only time he’s been hit hard in his professional career, that shot by Dillian Whyte in his last fight, it would have been all over if he had been in there with a big heavyweight who knew how to finish.
“This game is not all about body-building. It’s about knowing how to box. He’s getting knocked out.’ When it comes to world championship level, you have to set up the opening for the big punch with your jab. Then you have to be perfectly balanced to land the KO. How’s he going to do that with no jab and his feet all over the place?
“Martin’s not the greatest but he’s a big southpaw, which him awkward to fight, with a heavy punch, which makes him dangerous. He moves well and he’s calm, balanced and patient in the ring.
“Joshua needs a miracle. I genuinely hope he gets it. Because then he and I can both make a lot of money by boxing each other in a massive championship unification fight at Wembley Stadium. And that would be an easy fight for me. But he really is useless,” he added.
Fury is lined up to meet Wladimir Klitschko once again this summer following his standout victory over the former divisional ruler and could then meet the winner of Martin v Joshua at the end of 2016.
WBC champion Deontay Wilder is also in the mix to battle Fury, buy first needs to come through his toughest career test against Alexander Povetkin on May 21 in Russia.
