Dillian Whyte is paying very little attention to the recent challenge from heavyweight contender Dominic Breazeale.
The two boxers were ordered to fight each other in early 2019, but then Breazeale was granted a mandatory world title shot at then WBC world champion Deontay Wilder.
Wilder would knock Breazeale out with a single punch in the first round.
Whyte had since captured the WBC-interim title, which puts him in line for a crack at the winner of the trilogy fight between Wilder and now champion Tyson Fury.
Breazeale has since called for the fight with Whyte to take place.
But Whyte has very little interest in the fight - explaining that Breazeale blew him off last year.
"I accepted the fight [that was ordered by the WBC] and he pulled out of the fight, so there's nothing more to be said on that front," said Whyte to Sky Sports.
"These guys are time wasters. Clearly he's bored at home and trying to shake off his last knockout, and thinking, 'how can I get another big payday?' The guy is a chump. How can he have two world title fights? He didn't even deserve one of them. That's the reason he gets two world title fights, because he's easy work, easy money.
"He hasn't had a single fight since his embarrassing first-round knockout loss to that fraud Wilder, a man who humiliated him both inside and outside the ring. Shameful, pathetic excuse for a heavyweight boxer who should make a comeback and beat a few credible fighters before calling me out."
Whyte is slated for a return on July 4th in Manchester, against Olympic gold medal winner and former WBA champion Alexander Povetkin.
"Alexander Povetkin, an Olympic gold medallist, a former world champion," said Whyte.
"Only lost to Klitschko and Joshua. He's a tough guy and the one thing about Povetkin, he's technically good. He's very experienced and copes with the ups and downs in fights. I'm focused on him and I'll give him all the respect he has earned, that's why I'm out here in camp training."
