Anthony Joshua has invited Tyson Fury to his heavyweight title bout against Wladimir Klitschko after hitting back at his domestic rival's claim that he is a "poor man's Frank Bruno".
IBF champion Joshua is to meet Klitschko for the vacant IBO and WBA Super belts in a blockbuster clash at Wembley Stadium on April 29.
Fury previously held the belts after stunning Klitschko in November 2015, but has not fought since and is suspended pending a UK Anti-Doping hearing.
The Briton revealed he has ballooned to 25 stone during his absence from the ring, but has vowed to make a comeback and was typically outspoken about domestic rival Joshua on Twitter.
"@anthonyfjoshua is a poor mans @frankbrunoboxer," Fury wrote.
That prompted a swift reply from the undefeated Joshua, who claimed Fury always surfaces before his fights and telling him to come to Wembley to make his point.
"Typical @Tyson_Fury always tlking BS around fight time. Same offer as lst time. X2 ringside tickets dn't bring a plus 1 it's for ur fat ass," he replied.
Former heavyweight champion Bruno also had his say on the spat, advising the warring duo to save their words for the ring.
"I reckon you boys should just save it for the ring...let the [fighting] do the talking @Tyson_Fury & @anthonyfjoshua," he wrote.
