The British boxer prepares to battle the American YouTuber in an eight round fight which will be streamed in real-time on Netflix.
British boxer Anthony Joshua declared he will "stamp all over" the American and "break" the American as the combatants met personally to publicize next month's bout.
Former twice world heavyweight champion Anthony Joshua meets YouTuber-turned-boxer Paul - in what is, theoretically, a massive uneven pairing - at Miami's arena on 19 December.
Boxer's Mentality
"I will damage his features and break his body up. I aim to demonstrate I'm the better fighter," the British boxer, 35, declared.
"I will dominate him completely. That's how fighters think.
"I intend to seriously aim to injure him. That's what I want to do."
Civil Interaction
Despite such comments, a composed Joshua and social media star Jake Paul - usually known for his showmanship - were respectful and kept it respectful with each other.
Jake Paul instead attacked former Joshua rival the Cameroonian fighter and called him "ridiculous" after Ngannou rejected a bout proposal.
Targeting Tyson Fury
Joshua, meanwhile, took aim at British rival Fury - and declined a large bet 'The Gypsy King' states he will put on a victory for Paul.
"[Paul] is superior to Tyson Fury - he's actually sitting here," Joshua said.
"I give him credit for that."
Serious Fighter
Despite declaring he will damage his opponent, Anthony Joshua chose not to talk badly about his rival's boxing ability.
"Jake is a legitimate boxer," he remarked.
Jake Paul's History
Jake Paul - who first rose to fame on the television network - has mostly boxed MMA fighters or declining opponents since entering professional boxing.
He was defeated by Briton Fury in last year.
Financial Success
Nevertheless, the inexperienced fighter remains one of boxing's largest commercial attractions, regularly earning substantial financial rewards.
Forecast and Belief
The 28-year-old predicted a knockout win in the fourth or fifth round and asserted he would derail the long-awaited match between Joshua and Fury, which is apparently under discussion for two years from now.
"It will be me versus Tyson Fury in the coming year," Paul stated.
Size Difference
As the two fighters participated in the usual stare-down, with their size difference on show, it highlighted just how surprising this complete situation is - and how amazing it is that the bout is actually going ahead.
