British boxer Dillian Whyte has unleashed a scathing attack on Joseph Parker, as the Kiwi pushes for a future rematch.
In July 2018, Whyte became the first man to floor Parker in the professional ranks during a unanimous decision victory - the second straight loss of Parker's career.
Since then, Parker has pushed hard for a return bout, claiming he was stunned by headbutt from Whyte that went unseen by referee Ian John Lewis.
British promoter Eddie Hearn listed Whyte as a potential opponent for Parker in the near future, but the 'Body Snatcher' isn't interested at all.
Speaking to Sky Sports UK, Whyte said Parker would be "beaten up again" if they fought and challenged the 28-year-old to fight somebody "credible'', instead of "prancing around his kitchen".
During the coronavirus crisis, Parker has become a social media sensation, posting a series of entertaining lockdown videos that have delighted fans.
"I've beat him up already and I'll beat him up again," Whyte told Sky Sports. "Joseph Parker shouldn't be struggling with guys like Shawndell Winters.
"Who the hell is that guy? No-one has even heard of him.
"Instead of prancing around his kitchen, he should go fight someone credible like Derek Chisora or Oscar Rivas.
"I tried to fight Joseph Parker, before we even fought, when he was a champion. He didn't want to fight me, but he knows that fighting me now, he'll get a big payday."
"I fight Joseph Parker again, I will knock him out. I went into the fight with a broken hand and a broken rib, and I still destroyed him.
"I didn't outbox him, I beat him and dominated him. Imagine if I go in when I'm 100 percent, no injury, what's going to happen?
"The left hand was broken - it was the hand that I knocked him down with."
But Whyte's verbal tirade didn't stop there, lashing out at Parker's career choices.
"Joseph Parker has had a lot of opportunities and he's wasted them, simple as that.
"He had an opportunity to beat Anthony Joshua, he fought like a coward in the fight.
"He had an opportunity to beat me, he done alright, but he just talks crap. I'm sick of these heavyweights.
"If you don't really want it, don't call my name. When I wanted it, they didn't want to fight me."
Whyte is preparing to risk his status as interim WBC champion and mandatory challenger to the winner of Tyson Fury-Deontay Wilder III in his forthcoming bout against Alexander Povetkin, scheduled to take place at Manchester on July 5 (NZ time).
Parker doesn't have a fight scheduled, but Hearn listed former world champion Andy Ruiz Jr and Luis Ortiz as two potential future opponents.
Hearn also endorsed Kiwi Junior Fa, saying: "I like that fight for New Zealand, and I like the idea for us to come over to New Zealand and launch Matchroom to a new audience."
But earlier this month, Parker told Magic Talk that a Kiwi heavyweight showdown was unlikely, after Fa's camp "priced themselves out".
"It was in talks and there were discussions," Parker told Magic Talk on April 4.
"I said to my team, if it is going to get me closer to a title, I will take it in a heartbeat, but they asked for too much money and they priced themselves out.
"We had four fights as amateurs, I don't have anything against him and we're both top-10 fighters.
"If we did fight, I wouldn't be nervous, but the winner will get closer to a world title and the loser, it would be the end of their career."
