The British boxer will face Jake Paul in an eight-round match which will be shown in real-time on Netflix.
British boxer Anthony Joshua declared he will "overwhelm entirely" the American and "break" the American as the two fighters met personally to build hype for the upcoming bout.
Ex two-time world title holder Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, theoretically, a mammoth uneven pairing - at Miami arena on 19 December.
Fighter's Mentality
"I will injure his face and break his body up. My goal is to show I'm superior," Joshua, 35, said.
"I will dominate him completely. That's the boxer's mindset.
"I'm going to genuinely try to injure him. That's my intention."
Civil Exchange
In spite of such comments, a relaxed Joshua and social media star Jake Paul - usually recognized for his dramatics - shared friendly words and remained civil with each other.
Jake Paul instead attacked ex Joshua opponent the Cameroonian fighter and described him as "ridiculous" after Ngannou turned down a match opportunity.
Targeting Tyson Fury
Anthony Joshua, in the meantime, took aim at British rival Fury - and declined a large bet 'Tyson Fury' claims he will make on a victory for Paul.
"Jake Paul is superior to Tyson Fury - he's actually sitting here," the boxer said.
"I give him credit for that."
Serious Opponent
Despite saying he intends to damage his opponent, Joshua chose not to comment unfavorably about his opponent's fighting skills.
"Jake is a credible opponent," he said.
Paul's History
Jake Paul - who first rose to fame on the Disney Channel - has mostly boxed mixed martial artists or faded names since turning professional.
He lost to British fighter Tommy Fury in last year.
Commercial Success
Nevertheless, the inexperienced fighter continues to be one of boxing's greatest money-making draws, consistently making massive paydays.
Prediction and Confidence
The 28-year-old predicted a KO victory in rounds four or five and asserted he would stop the highly-expected Fury-Joshua bout, which is apparently under discussion for two years from now.
"It will be me versus Tyson Fury in the coming year," Paul declared.
Physical Disparity
As both boxers engaged in the usual confrontation, with their size difference on show, it highlighted just how improbable this entire matchup is - and how astonishing it is that the bout is actually going ahead.
