Anthony Joshua is set to fight Jake Paul in an eight round fight which will be broadcast in real-time on the streaming platform.
British boxer Joshua declared he will "dominate completely" the American and "overpower" his opponent as the pair came face-to-face to build hype for next month's bout.
Ex twice world boxing king Anthony Joshua meets YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a mammoth uneven pairing - at Miami Kaseya Center on 19 December.
Boxer's Attitude
"I will damage his features and damage his physique. I'm here to prove I'm superior," Joshua, 35 years old, said.
"I'll stamp all over him. That's a fighter's mentality.
"I intend to seriously aim to injure him. That's my goal."
Respectful Exchange
In spite of those words, a relaxed Joshua and internet personality Jake Paul - typically known for his theatrics - exchanged pleasantries and kept it respectful with each other.
Jake Paul instead attacked former Joshua's opponent the Cameroonian fighter and described him as "a joke" after the Cameroonian declined a fight offer.
Targeting Fury
Joshua, in the meantime, targeted British opponent Tyson Fury - and refused a million-pound wager 'The Gypsy King' states he will put on a victory for Paul.
"Jake Paul outshines Tyson Fury - he's present here," Joshua said.
"I give him credit for that."
Serious Fighter
Despite declaring he will hurt Jake Paul, Joshua declined to speak negatively about his opponent's fighting skills.
"Jake is a legitimate boxer," he said.
Jake Paul's Background
Jake Paul - who first rose to fame on the Disney Channel - has mostly fought mixed martial artists or past-their-prime fighters since becoming pro.
He was defeated by Briton Tommy Fury in last year.
Commercial Attraction
Nevertheless, the novice remains one of boxing's greatest financial successes, regularly earning massive financial rewards.
Prediction and Belief
The 28 year old predicted a knockout win in round four or five and asserted he would derail the long-awaited match between Joshua and Fury, which is allegedly being planned for 2026.
"The next fight will be myself against Tyson Fury next year," Jake Paul declared.
Physical Disparity
As Joshua and Paul participated in the traditional stare-down, with their physical disparity on show, it emphasized just how improbable this whole event is - and how amazing it is that the bout is truly happening.
