Tyson Fury has told Anthony Joshua he should vacate his WBO title rather than risk facing Oleksandr Usyk.
Joshua holds three of the four major world titles and his next two fights could be against mandatory challengers.
IBF mandatory challenger Kubrat Pulev already has his shot against Joshua in the bag, while Usyk recently insisted he had no intention of stepping aside to allow an undisputed clash between AJ and Fury.
The Gypsy King wants the fight to happen as soon as possible and offered some advice to his rival heavyweight champion.
“Rather than fight all these mandatories he’s got, I’d say just vacate those belts and fight the fight everyone wants to see,” Fury told Behind the Gloves.
“I ain’t running from you, I don’t care about you. I’ll go through you like a knife through butter.
“Come and fight the big boy, step up to the plate and get knocked out.
“Then fight all those easy guys. No disrespect to Oleksandr Usyk – great fighter, cruiserweight world champion, probably going to be heavyweight champion if he fights Anthony Joshua – but don’t take my retirement cheque, baby.
“Don’t do it. I said to Deontay Wilder years ago, ‘do not take my retirement fund, do not fight Joshua, He’s mine. He’s mine countryman, I’m having him, I’m breaking him in!’
“But it didn’t happen. He got broke in by an unlikely suspect. It was what it was.”
Pressed on if he thought Usyk would beat Joshua, Fury replied: “If they fight, but I bet they don’t.
“Because why would he fight Usyk and get 10 per cent of what he can make off the Gypsy King.
“Vacate it, let them boys fight for the vacated belt, whoever it is, Usyk and (Joseph) Parker. We’re at the top of the game.
“We’re in this boxing to fight the biggest fights out there.
“It’s a boxing match, what’s the worse that can happen? You can lose? Big deal.”
