The British boxer is set to fight the American YouTuber in an eight-round contest which will be shown in real-time on the streaming platform.
British boxer Anthony Joshua said 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.
Ex twice world title holder Anthony Joshua faces social media star turned fighter Jake Paul - in what is, on paper, a huge disparity - at Miami Kaseya Center on 19 December.
Fighter's Attitude
"I will break his face and break his body up. My goal is to show I'm the better fighter," the British boxer, 35 years old, stated.
"I plan to overwhelm him. That's a fighter's mentality.
"I'm going to seriously aim to injure him. That's my intention."
Respectful Exchange
Despite such comments, a calm Joshua and internet personality Paul - usually famous for his dramatics - exchanged pleasantries and remained civil with each other.
Paul instead attacked ex Joshua's rival Francis Ngannou and described him as "not serious" after Ngannou turned down a match opportunity.
Targeting Tyson Fury
Anthony Joshua, in the meantime, criticized UK opponent Fury - and declined a £1m bet 'Tyson Fury' states he will put on a Paul victory.
"Jake Paul is superior to Fury - he showed up," Joshua commented.
"I give him credit for that."
Serious Opponent
In spite of declaring he will punish Paul, Anthony Joshua refused to talk badly about his opponent's pugilistic talent.
"Jake is a legitimate boxer," he said.
Jake Paul's Background
Paul - who originally gained popularity on the Disney Channel - has mostly fought MMA fighters or past-their-prime fighters since turning professional.
He lost to British fighter Fury in last year.
Commercial Success
Still, the inexperienced fighter continues to be one of the sport's biggest financial successes, regularly earning huge financial rewards.
Forecast and Confidence
The 28 year old anticipated a KO victory in the fourth or fifth round and claimed he would derail the much-anticipated match between Joshua and Fury, which is allegedly being planned for two years from now.
"It's going to be my match with Fury in the coming year," Paul stated.
Physical Difference
As Joshua and Paul engaged in the customary confrontation, with their physical disparity on show, it emphasized just how surprising this complete situation is - and how astonishing it is that the fight is truly happening.
