Tyson Fury has branded Anthony Joshua “a poor man’s Frank Bruno” as the pair clashed on social media ahead of the Olympic champion’s showdown with Wladimir Klitschko at the end of the month.

Joshua, who currently holds Fury’s former IBF heavyweight belt, will be battling the Ukrainian at Wembley on April 29th to add the WBA (Super) and IBO belts to his own.

It will be Klitschko’s first return to the ring since his shock defeat to Fury on points in Germany in November 2015.

And Fury, who had to vacate his titles last year, took to Twitter to swipe a shot at Joshua ahead of the fight.

“Anthony Joshua is a poor man’s Frank Bruno,” he wrote.

Joshua was quick to shoot back though, replying saying: “Typical Tyson Fury, always talking BS around fight time. Same offer as last time. Two ringside tickets – don’t bring a plus one, it’s for your fat ass.”

Fury, who is currently in training himself for his long-awaited comeback after drug issues and depression, then responded: “I might be fat, but you’re a paper champ and paper chinned weightlifting rudeboy wannabe badman! Know your place chump! Or I’ll come back and KO you.”

Joshua responded by offering Fury a shot at getting his titles back, only for Fury to tell him to concentrate on Klitschko before they set up a date to fight.

Joshua said: “Shut up and give me a date when you’ll be back! You’re the only reason we haven’t had a fight yet! Be about what you say. I ain’t going nowhere.”
