The British boxer will face Jake Paul in an eight-round contest which will be shown live on the streaming platform.
Briton Joshua stated he will "stamp all over" Jake Paul and "defeat" the American as the pair came face-to-face to promote next month's heavyweight fight.
Ex two time world title holder Anthony Joshua meets social media star turned fighter Jake Paul - in what is, theoretically, a mammoth disparity - at Miami arena on 19 December.
Fighter's Attitude
"I'm going to break his face and hurt his body. I aim to demonstrate I'm the better fighter," the British boxer, 35 years old, declared.
"I will dominate him completely. That's the boxer's mindset.
"I will seriously aim to cause him pain. That's my goal."
Respectful Exchange
Despite such comments, a relaxed Joshua and internet personality Jake Paul - usually famous for his showmanship - shared friendly words and maintained decorum with each other.
Paul rather targeted former Joshua opponent the Cameroonian fighter and called him "a joke" after Ngannou declined a fight offer.
Taking Aim at Tyson Fury
Anthony Joshua, at the same time, criticized UK opponent Tyson Fury - and declined a million-pound wager 'The Gypsy King' claims he will make on a Paul victory.
"[Paul] is better than Fury - he's present here," the boxer stated.
"I acknowledge that."
Legitimate Fighter
Despite stating he plans to hurt Jake Paul, Anthony Joshua refused to speak negatively about his rival's pugilistic talent.
"Jake Paul is a credible opponent," he stated.
Jake Paul's Background
Jake Paul - who originally gained popularity on the Disney Channel - has primarily boxed mixed martial artists or faded names since becoming pro.
He lost to Briton Tommy Fury in last year.
Financial Success
Nevertheless, the novice remains one of the sport's biggest commercial attractions, regularly earning huge earnings.
Prediction and Confidence
The 28 year old forecast a KO victory in rounds four or five and asserted he would stop the much-anticipated match between Joshua and Fury, which is allegedly in the works for 2026.
"The next fight will be myself against Tyson Fury in the coming year," Paul stated.
Physical Disparity
As the two fighters met for the usual stare-down, with their physical disparity evident, it emphasized just how improbable this entire matchup is - and how amazing it is that the fight is actually happening.
