WBC heavyweight champion Deontay Wilder has come out fighting at past criticism from former cruiserweight champion Tony Bellew in a fiery interview.

The retired Brit previously stated that Wilder was 'the worst, least technically gifted heavyweight champion ever', which has prompted a passionate response from the 33-year-old American.

It would seem like Bellew is one of the last boxers to be called out by Wilder, but the Evertonian ruthlessly slated him in an interview last week, somewhat out of the blue.

Speaking to ThaBoxingVoice, Wilder surprisingly challenged Bellew to a fight and even suggested he’d drop a weight class in order for it to happen.

“You know Tony Bellew’s a b***h. He was scared during that time and he’s scared now. I’ll still go down in weight. I can still lose weight.

“One thing I know how to do is go down. Any of these clowns around here want to try Deontay Wilder, give me a chance? Meet me at a catchweight.

"Sometimes it’s about principle. This is a principle ass whooping right here,” Wilder added.

“If Bellew ever wants this, if he ever wants this work, let me know. I’ll get down or you can come up, whatever you comfortable with.”

Of course, Bellew is highly unlikely to accept Wilder’s kind offer considering he retired in November last year after a conclusive defeat to Oleksandr Usyk at Manchester Arena.

As for Wilder, he and Tyson Fury fought out an exhilarating draw in Los Angeles at the start of December last year, a result that many British fans thought should’ve been a victory for the latter, and despite the controversial draw, a rematch is yet to be agreed.

The champion called out his rival on Twitter on Thursday, calling him a “lying rat” after Fury teased him about his $100million deal with ESPN before calling him a “dosser.”

It seems like there’s plenty left to be decided between Wilder and Fury, but if Bellew responds to the former’s attack, we might have another war of words on our hands in the boxing world.

For now, however, it looks like we'll have Wilder vs Dominic Breazeale and then whoever Fury ends up fighting.
