Anthony Joshua will face the American YouTuber in an eight-round fight which will be streamed in real-time on Netflix.
Briton Joshua declared he will "dominate completely" the American and "defeat" the American as the combatants came face-to-face to promote the upcoming bout.
Former two-time world boxing king Joshua battles YouTuber-turned-boxer Jake Paul - in what is, theoretically, a huge uneven pairing - at Miami venue on 19 December.
Fighter's Attitude
"I'm going to break his face and hurt his body. I'm here to prove I'm the better fighter," Joshua, 35, stated.
"I'll stamp all over him. That's the boxer's mindset.
"I'm going to seriously aim to injure him. That's what I want to do."
Civil Exchange
In spite of these statements, a composed Joshua and internet personality Paul - normally known for his dramatics - were respectful and kept it respectful with each other.
Paul rather targeted ex Joshua opponent the Cameroonian fighter and called him "a joke" after Ngannou declined a bout proposal.
Taking Aim at Fury
Joshua, in the meantime, criticized British opponent Tyson Fury - and declined a million-pound wager 'Tyson Fury' claims he will make on a Paul win.
"Jake Paul is better than Tyson Fury - he's actually sitting here," Joshua said.
"I give him credit for that."
Legitimate Fighter
In spite of saying he intends to damage his opponent, Anthony Joshua refused to speak negatively about his rival's boxing ability.
"Jake Paul is a credible opponent," he stated.
Paul's History
Paul - who initially became famous on the Disney Channel - has mainly fought mixed martial artists or declining opponents since becoming pro.
He lost to British fighter Fury in last year.
Financial Attraction
However, the inexperienced fighter remains one of boxing's biggest commercial attractions, frequently receiving massive paydays.
Prediction and Belief
The 28 year old anticipated a knockout win in rounds four or five and stated he would derail the highly-expected match between Joshua and Fury, which is allegedly under discussion for two years from now.
"It will be me versus Tyson Fury next year," Jake Paul stated.
Physical Disparity
As both boxers participated in the traditional stare-down, with their height and weight contrast clearly visible, it drove home just how surprising this complete situation is - and how astonishing it is that the bout is really going ahead.
