The British boxer will face the American YouTuber in an eight-round fight which will be broadcast live on Netflix.
British boxer Anthony Joshua said he will "dominate completely" Jake Paul and "break" the American as the pair came face-to-face to publicize the upcoming heavyweight fight.
Ex twice unified boxing king Anthony Joshua faces YouTuber-turned-boxer Paul - in what is, by the numbers, a mammoth uneven pairing - at Miami's venue on December 19th.
"I will injure his face and break his body up. I aim to demonstrate my superiority," Joshua, 35, declared.
"I plan to overwhelm him. That's how fighters think.
"I intend to seriously aim to injure him. That's my goal."
Despite those words, a relaxed Anthony Joshua and social media star Jake Paul - usually recognized for his theatrics - exchanged pleasantries and maintained decorum with each other.
Jake Paul instead attacked ex Joshua's rival the Cameroonian fighter and called him "ridiculous" after Ngannou rejected a match opportunity.
Anthony Joshua, at the same time, targeted UK rival Fury - and declined a £1m bet 'The Gypsy King' claims he will make on a victory for Paul.
"[Paul] is superior to Fury - he's present here," the boxer commented.
"I give him credit for that."
In spite of declaring he will hurt Jake Paul, Joshua chose not to talk badly about his opponent's fighting skills.
"Jake is a legitimate boxer," he stated.
Paul - who originally gained popularity on the Disney Channel - has mostly fought mixed martial artists or declining opponents since entering professional boxing.
He was defeated by British fighter Fury in last year.
However, the relative newcomer is still one of the sport's biggest commercial attractions, regularly earning massive earnings.
The 28-year-old predicted a knockout win in rounds four or five and claimed he would stop the much-anticipated Joshua–Fury fight, which is apparently being planned for 2026.
"It's going to be myself against Tyson Fury next year," Jake Paul declared.
As both boxers met for the traditional confrontation, with their physical disparity clearly visible, it highlighted just how surprising this whole event is - and how remarkable it is that the bout is truly going ahead.
