Anthony Joshua has savagely mocked Tyson Fury for fighting Otto Wallin in his next bout.
Fury will return to action on September 14 when he faces Wallin in Las Vegas, but his decision to fight the unheralded Swede has angered the boxing community, including Joshua who has taken a swipe at him.
"Fury's gonna fight Otto Wallin, no-one talks about that," the ex-heavyweight world champion said.
"I fought Wallin as an amateur. These guys are cream of the crop, they shouldn't be fighting them type of people... I can't fight Wallin, don't think I can ever fight lower-tier heavyweights."

Joshua beat Wallin twice during his amateur days before turning professional. Wallin has since joined him in the professional ranks and has compiled a 20-0 record.
WBC world champion Deontay Wilder has also voiced his displeasure over Fury's upcoming opponent.
"He keeps pulling out all these night shift graveyard workers... Bulls*** at its best," he said.
"No Englishman's coming over here, saving America with Tom Schwarz and Otto whoever he is, talking about 'he's the best' with an invisible belt.
"First of all, Fury came with his last fight against Tom Schwarz, he went to Vegas, came out with this clown outfit on, (talking about) how he's going to save America and make America great again.
"There were only 5,000 fans in the audience, but he swears up and down he was the 'it factor' to our fight, it's proof in the pudding that he's irrelevant in America."
Wilder and Fury are set to run it back next year following their controversial 2018 bout, which ended in a draw.
Joshua, on the other hand, will rematch Andy Ruiz Jr for the heavyweight world titles on December 7, though Team Ruiz Jr continue to insist that the fight won't take place in Saudi Arabia.
