The British boxer will face Jake Paul in an eight-bout contest which will be shown live on the streaming platform.
Briton Anthony Joshua declared he will "overwhelm entirely" Jake Paul and "overpower" his opponent as the pair met personally to promote the upcoming heavyweight fight.
Former twice unified boxing king Joshua faces YouTuber-turned-boxer Paul - in what is, theoretically, a massive disparity - at Miami's arena on December 19th.
Boxer's Mindset
"I'm going to injure his face and break his body up. I aim to demonstrate I'm the better fighter," Joshua, 35, said.
"I'll stamp all over him. That's the boxer's mindset.
"I will seriously aim to cause him pain. That's my goal."
Civil Exchange
In spite of these statements, a composed Anthony Joshua and internet personality Paul - usually recognized for his dramatics - exchanged pleasantries and maintained decorum with each other.
Paul rather attacked ex Joshua opponent the Cameroonian fighter and labeled him "a joke" after Ngannou turned down a match opportunity.
Taking Aim at Fury
Joshua, at the same time, took aim at British opponent Tyson Fury - and rejected a large bet 'Tyson Fury' says he will place on a Paul victory.
"[Paul] is superior to Fury - he showed up," the boxer stated.
"I give him credit for that."
Serious Opponent
Despite declaring he will punish Paul, Anthony Joshua refused to talk badly about his rival's pugilistic talent.
"Jake is a serious fighter," he remarked.
Jake Paul's History
Paul - who originally gained popularity on the television network - has mainly boxed mixed martial artists or faded names since becoming pro.
He was defeated by British fighter Fury in last year.
Financial Success
Still, the relative newcomer is still one of boxing's biggest commercial attractions, regularly earning substantial financial rewards.
Prediction and Belief
The 28 year old forecast a knockout win in round four or five and claimed he would derail the long-awaited Joshua–Fury fight, which is apparently in the works for two years from now.
"It will be my match with Fury in the coming year," Paul declared.
Physical Difference
As the two fighters participated in the customary stare-down, with their physical disparity clearly visible, it emphasized just how unlikely this whole event is - and how remarkable it is that the fight is really going ahead.
