Anthony Joshua will face Jake Paul in an eight round match which will be streamed in real-time on Netflix.
British boxer Joshua said he will "dominate completely" the American and "defeat" the American as the combatants met personally to publicize the upcoming heavyweight fight.
Ex twice world boxing king Anthony Joshua meets YouTuber-turned-boxer Jake Paul - in what is, on paper, a huge disparity - at Miami's venue on 19 December.
Fighter's Mentality
"I will break his face and hurt his body. My goal is to show I'm superior," Joshua, 35 years old, declared.
"I'll stamp all over him. That's a fighter's mentality.
"I will seriously aim to hurt him. That's my goal."
Respectful Exchange
In spite of these statements, a calm Anthony Joshua and internet personality Paul - usually known for his dramatics - exchanged pleasantries and maintained decorum with each other.
Jake Paul instead criticized former Joshua rival Francis Ngannou and called him "ridiculous" after Ngannou turned down a fight offer.
Targeting Fury
Anthony Joshua, at the same time, took aim at British opponent Fury - and declined a £1m bet 'The Gypsy King' states he will put on a Paul win.
"Jake Paul is better than Tyson Fury - he's present here," the boxer said.
"I acknowledge that."
Serious Opponent
Despite saying he intends to hurt Jake Paul, Anthony Joshua refused to comment unfavorably about his opponent's fighting skills.
"Jake is a serious fighter," he remarked.
Paul's Background
Jake Paul - who originally gained popularity on the Disney Channel - has primarily fought mixed martial artists or faded names since turning professional.
He lost to British fighter Tommy Fury in last year.
Financial Success
Still, the relative newcomer remains one of the sport's largest money-making draws, consistently making substantial financial rewards.
Forecast and Belief
The 28-year-old forecast a knockout win in the fourth or fifth round and claimed he would derail the highly-expected match between Joshua and Fury, which is reportedly under discussion for two years from now.
"It's going to be my match with Fury next year," Jake Paul stated.
Size Disparity
As Joshua and Paul met for the customary confrontation, with their height and weight contrast evident, it highlighted just how surprising this complete situation is - and how amazing it is that the fight is actually going ahead.
