The British boxer will face Jake Paul in an eight-bout match which will be streamed live on Netflix.
British boxer Anthony Joshua said he will "stamp all over" the American and "break" his opponent as the two fighters met personally to build hype for next month's heavyweight fight.
Former two-time unified title holder Joshua meets YouTuber-turned-boxer Paul - in what is, on paper, a huge uneven pairing - at Miami venue on December 19th.
Fighter's Mentality
"I will injure his face and damage his physique. I'm here to prove my superiority," the British boxer, 35 years old, said.
"I will dominate him completely. That's how fighters think.
"I'm going to seriously aim to injure him. That's my intention."
Respectful Exchange
Despite these statements, a relaxed Joshua and internet personality Jake Paul - usually recognized for his showmanship - were respectful and maintained decorum with each other.
Paul rather attacked former Joshua's rival the Cameroonian fighter and described him as "a joke" after Ngannou rejected a bout proposal.
Targeting Fury
Anthony Joshua, meanwhile, took aim at UK opponent Tyson Fury - and declined a million-pound wager 'The Gypsy King' claims he will make on a Paul win.
"[Paul] is superior to Fury - he's present here," Joshua commented.
"I respect him for that."
Legitimate Opponent
In spite of saying he intends to punish Paul, Joshua refused to comment unfavorably about his opponent's pugilistic talent.
"Jake is a legitimate boxer," he said.
Paul's History
Jake Paul - who first rose to fame on the television network - has mostly boxed MMA fighters or declining opponents since turning professional.
He lost to Briton Fury in last year.
Financial Success
Still, the inexperienced fighter continues to be one of the sport's biggest commercial attractions, consistently making massive financial rewards.
Prediction and Belief
The 28 year old forecast a KO victory in round four or five and stated he would derail the long-awaited match between Joshua and Fury, which is allegedly being planned for two years from now.
"The next fight will be myself against Tyson Fury next year," Jake Paul declared.
Physical Disparity
As both boxers participated in the usual stare-down, with their size difference on show, it emphasized just how unlikely this whole event is - and how remarkable it is that the match is really going ahead.
