Tyson Fury pulled no punches with his response to Anthony Joshua over criticism of Tom Schwarz.
Joshua spoke out about Fury's opponent by taking a shot at Schwarz's modest ranking. He poked fun of his position within the governing bodies, saying he was ranked 56th.
"Thoughts on Tyson Fury's win? He done what he had to. I could talk s*** but he done what he had to, well played to him," he said.
"I wanna go back to fighting some easy opponents," he added, before being asked where he was ranked. "56th. I think, why am out here doing all this s*** myself? D'ya know what I mean?"
Fury, who beat Schwarz in the second-round, has hit back in typically fiery fashion.
"I've seen something from Joshua recently saying he wishes he could go back to fighting easy opponents," the self-proclaimed 'Gypsy King' said.
"Couldn't get easier than the opponent he had could he? Two weeks' notice and fat as a pig.
"I don't think they come easier than that mush!
"Where was he ranked? Number 15 or 16 by the organisations? He said Tom Schwarz was rated number 69 in the world - Tom Schwarz was rated number two by the WBO."
The lineal heavyweight champion then verbally jabbed Joshua's promoter Eddie Hearn.
The Matchroom boss claimed Schwarz wouldn't be good enough to win the British heavyweight title
"I have no interest in anything Eddie Hearn says, of course Eddie Hearn would say something negative wouldn't he because his golden goose has just been splattered by a fat man," Fury said.
"So he's got to try to discredit me to try and make himself look good.
"Let me guess, Tom Schwarz is rubbish but Dillian Whyte is brilliant. And Joshua is brilliant but Tyson is rubbish, and everyone else he's got... Dereck Chisora, Carlos Takam, Oleksandr Usyk - he's brilliant isn't he - but everybody else is crap."
After recording his 28th professional victory in Las Vegas, Fury could face WBC champion Deontay Wilder next.
Joshua, on the other hand, is set to rematch Andy Ruiz Jr before the end of the year.
