The British boxer will face Jake Paul in an eight-round fight which will be streamed in real-time on the streaming platform.
Briton Joshua stated he will "dominate completely" Jake Paul and "overpower" the American as the two fighters confronted each other to build hype for next month's bout.
Ex twice unified title holder Joshua battles social media star turned fighter Paul - in what is, on paper, a huge uneven pairing - at Miami's arena on December 19th.
Fighter's Attitude
"I will injure his face and break his body up. I aim to demonstrate my superiority," Joshua, 35, stated.
"I plan to overwhelm him. That's the boxer's mindset.
"I'm going to seriously aim to cause him pain. That's what I want to do."
Civil Exchange
Despite those words, a calm Anthony Joshua and social media star Jake Paul - typically known for his showmanship - were respectful and kept it respectful with each other.
Paul rather targeted ex Joshua's rival Francis Ngannou and described him as "a joke" after Ngannou declined a match opportunity.
Taking Aim at Fury
Anthony Joshua, in the meantime, targeted UK opponent Fury - and rejected a large bet 'The Gypsy King' states he will put on a victory for Paul.
"[Paul] is better than Fury - he's present here," Joshua commented.
"I acknowledge that."
Legitimate Opponent
Despite declaring he will punish Paul, Anthony Joshua chose not to talk badly about his rival's pugilistic talent.
"Jake Paul is a legitimate boxer," he stated.
Paul's History
Jake Paul - who originally gained popularity on the television network - has mainly fought MMA fighters or declining opponents since turning professional.
He lost to British fighter Tommy Fury in last year.
Commercial Success
However, the inexperienced fighter continues to be one of the sport's biggest money-making draws, consistently making huge financial rewards.
Prediction and Belief
The 28-year-old forecast a stoppage in rounds four or five and stated he would derail the long-awaited Fury-Joshua bout, which is allegedly being planned for two years from now.
"The next fight will be my match with Fury in the coming year," Paul said.
Physical Disparity
As Joshua and Paul engaged in the usual stare-down, with their size difference clearly visible, it emphasized just how surprising this complete situation is - and how amazing it is that the fight is really proceeding.
