Anthony Joshua will face Jake Paul in an eight round contest which will be streamed in real-time on Netflix.
Briton Joshua said he will "stamp all over" Jake Paul and "defeat" his opponent as the two fighters met personally to promote next month's boxing match.
Former twice world title holder Joshua battles social media star turned fighter Paul - in what is, on paper, a huge disparity - at Miami's Kaseya Center on 19 December.
Fighter's Attitude
"I'm going to injure his face and hurt his body. My goal is to show my superiority," the British boxer, 35 years old, stated.
"I'll stamp all over him. That's the boxer's mindset.
"I'm going to genuinely try to hurt him. That's what I want to do."
Respectful Exchange
Despite such comments, a relaxed Joshua and social media star Paul - typically recognized for his theatrics - shared friendly words and kept it respectful with each other.
Jake Paul rather targeted former Joshua opponent the Cameroonian fighter and labeled him "a joke" after the Cameroonian turned down a match opportunity.
Taking Aim at Fury
Anthony Joshua, at the same time, criticized British opponent Tyson Fury - and rejected a million-pound wager 'The Gypsy King' says he will place on a Paul win.
"Jake Paul outshines Tyson Fury - he's actually sitting here," Joshua stated.
"I respect him for that."
Legitimate Fighter
Despite declaring he will punish Paul, Joshua chose not to comment unfavorably about his rival's boxing ability.
"Jake is a legitimate boxer," he stated.
Paul's Background
Paul - who originally gained popularity on the Disney Channel - has mainly fought mixed martial artists or declining opponents since turning professional.
He lost to British fighter Fury in last year.
Commercial Success
Nevertheless, the novice continues to be one of boxing's biggest financial successes, frequently receiving huge financial rewards.
Prediction and Belief
The 28 year old predicted a KO victory in the fourth or fifth round and stated he would prevent the highly-expected match between Joshua and Fury, which is apparently under discussion for two years from now.
"It will be my match with Fury in the coming year," Jake Paul stated.
Size Disparity
As both boxers met for the usual stare-down, with their height and weight contrast evident, it emphasized just how unlikely this whole event is - and how remarkable it is that the bout is truly proceeding.
