Anthony Joshua will face the American YouTuber in an eight round contest which will be broadcast live on the streaming platform.
Briton Anthony Joshua declared he will "overwhelm entirely" Jake Paul and "overpower" the American as the combatants came face-to-face to build hype for next month's bout.
Former two time unified heavyweight champion Joshua meets YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a huge mismatch - at Miami venue on 19 December.
Boxer's Attitude
"I will injure his face and break his body up. I'm here to prove my superiority," Joshua, 35 years old, said.
"I'll stamp all over him. That's a fighter's mentality.
"I'm going to genuinely try to injure him. That's what I want to do."
Civil Interaction
Despite these statements, a calm Anthony Joshua and internet personality Jake Paul - typically famous for his theatrics - were respectful and kept it respectful with each other.
Paul rather attacked ex Joshua's opponent Francis Ngannou and described him as "a joke" after the Cameroonian declined a match opportunity.
Taking Aim at Fury
Anthony Joshua, in the meantime, targeted UK rival Fury - and declined a million-pound wager 'The Gypsy King' claims he will make on a Paul victory.
"Jake Paul is better than Tyson Fury - he's present here," Joshua said.
"I acknowledge that."
Legitimate Fighter
In spite of saying he intends to punish Paul, Anthony Joshua declined to talk badly about his rival's boxing ability.
"Jake Paul is a credible opponent," he said.
Jake Paul's Background
Jake Paul - who originally gained popularity on the Disney Channel - has mainly boxed mixed martial artists or past-their-prime fighters since becoming pro.
He lost to British fighter Tommy Fury in last year.
Financial Attraction
Nevertheless, the relative newcomer is still one of boxing's largest financial successes, consistently making substantial paydays.
Prediction and Confidence
The 28-year-old forecast a stoppage in the fourth or fifth round and asserted he would derail the much-anticipated Fury-Joshua bout, which is apparently being planned for two years from now.
"It's going to be my match with Fury in the coming year," Jake Paul said.
Size Difference
As the two fighters engaged in the customary face-off, with their physical disparity clearly visible, it emphasized just how improbable this complete situation is - and how astonishing it is that the fight is truly happening.
