The British boxer will face Jake Paul in an eight round fight which will be shown in real-time on the streaming platform.
Briton Anthony Joshua stated he will "dominate completely" Jake Paul and "defeat" his opponent as the pair confronted each other to build hype for the upcoming bout.
Former twice unified boxing king Joshua battles YouTuber-turned-boxer Jake Paul - in what is, theoretically, a mammoth disparity - at Miami's arena on 19 December.
Fighter's Attitude
"I'm going to break his face and break his body up. I aim to demonstrate my superiority," Joshua, 35, stated.
"I'll stamp all over him. That's how fighters think.
"I will really want to cause him pain. That's my intention."
Respectful Interaction
In spite of such comments, a composed Anthony Joshua and social media star Paul - usually famous for his showmanship - shared friendly words and remained civil with each other.
Jake Paul rather attacked former Joshua rival Francis Ngannou and called him "a joke" after the Cameroonian declined a match opportunity.
Taking Aim at Fury
Joshua, in the meantime, criticized UK rival Fury - and rejected a large bet 'The Gypsy King' claims he will make on a Paul win.
"Jake Paul outshines Fury - he's actually sitting here," Joshua stated.
"I acknowledge that."
Legitimate Opponent
Despite declaring he will hurt Jake Paul, Anthony Joshua chose not to talk badly about his rival's fighting skills.
"Jake Paul is a credible opponent," he remarked.
Jake Paul's History
Paul - who first rose to fame on the Disney Channel - has mainly boxed mixed martial artists or faded names since becoming pro.
He lost to British fighter Tommy Fury in last year.
Financial Success
Still, the relative newcomer is still one of boxing's greatest money-making draws, regularly earning massive financial rewards.
Prediction and Confidence
The 28-year-old predicted a stoppage in the fourth or fifth round and stated he would derail the highly-expected Fury-Joshua bout, which is apparently being planned for 2026.
"It will be me versus Tyson Fury in the coming year," Paul said.
Physical Difference
As the two fighters engaged in the customary face-off, with their physical disparity on show, it highlighted just how unlikely this complete situation is - and how astonishing it is that the fight is actually going ahead.
