Anthony Joshua will face the American YouTuber in an eight-bout contest which will be broadcast in real-time on the streaming platform.
Briton Anthony Joshua declared he will "overwhelm entirely" Jake Paul and "break" the American as the pair came face-to-face to promote the upcoming heavyweight fight.
Former two time unified title holder Anthony Joshua faces YouTuber-turned-boxer Paul - in what is, on paper, a massive mismatch - at Miami's venue on 19 December.
Fighter's Mentality
"I will damage his features and damage his physique. My goal is to show I'm superior," the British boxer, 35, said.
"I will dominate him completely. That's a fighter's mentality.
"I will seriously aim to cause him pain. That's my intention."
Respectful Exchange
Despite these statements, a calm Joshua and social media star Jake Paul - normally recognized for his showmanship - shared friendly words and maintained decorum with each other.
Paul instead targeted ex Joshua rival the Cameroonian fighter and called him "not serious" after Ngannou rejected a fight offer.
Taking Aim at Tyson Fury
Joshua, meanwhile, took aim at UK opponent Fury - and declined a large bet 'The Gypsy King' says he will place on a Paul win.
"Jake Paul outshines Fury - he showed up," Joshua said.
"I respect him for that."
Legitimate Opponent
Despite declaring he will punish Paul, Joshua chose not to speak negatively about his rival's boxing ability.
"Jake Paul is a legitimate boxer," he stated.
Jake Paul's Background
Jake Paul - who first rose to fame on the Disney Channel - has mostly boxed MMA fighters or declining opponents since entering professional boxing.
He lost to British fighter Tommy Fury in last year.
Financial Success
Still, the novice is still one of boxing's biggest commercial attractions, frequently receiving huge earnings.
Prediction and Belief
The 28-year-old forecast a knockout win in rounds four or five and asserted he would prevent the highly-expected Joshua–Fury fight, which is apparently being planned for two years from now.
"It's going to be me versus Tyson Fury in the coming year," Paul stated.
Size Difference
As Joshua and Paul met for the usual stare-down, with their size difference on show, it drove home just how improbable this whole event is - and how amazing it is that the fight is actually going ahead.
