Anthony Joshua will face the American YouTuber in an eight round fight which will be shown live on Netflix.
British boxer Joshua said he will "overwhelm entirely" Jake Paul and "break" the American as the two fighters met personally to promote the upcoming heavyweight fight.
Ex two time unified boxing king Joshua faces YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a mammoth mismatch - at Miami's Kaseya Center on December 19th.
Fighter's Mentality
"I will damage his features and break his body up. I aim to demonstrate I'm the better fighter," Joshua, 35 years old, stated.
"I'll stamp all over him. That's the boxer's mindset.
"I will genuinely try to hurt him. That's my goal."
Respectful Interaction
In spite of those words, a relaxed Anthony Joshua and social media star Paul - typically famous for his dramatics - were respectful and remained civil with each other.
Paul rather targeted ex Joshua's opponent the Cameroonian fighter and described him as "a joke" after Ngannou turned down a bout proposal.
Taking Aim at Tyson Fury
Joshua, at the same time, targeted British rival Tyson Fury - and rejected a million-pound wager 'Tyson Fury' claims he will make on a Paul victory.
"[Paul] outshines Fury - he's actually sitting here," the boxer said.
"I acknowledge that."
Serious Opponent
In spite of stating he plans to hurt Jake Paul, Joshua refused to talk badly about his opponent's boxing ability.
"Jake is a credible opponent," he stated.
Paul's Background
Paul - who originally gained popularity on the television network - has primarily fought MMA fighters or declining opponents since entering professional boxing.
He lost to Briton Tommy Fury in last year.
Financial Attraction
Still, the inexperienced fighter remains one of the sport's biggest commercial attractions, regularly earning huge paydays.
Prediction and Belief
The 28-year-old predicted a knockout win in the fourth or fifth round and asserted he would stop the highly-expected Fury-Joshua bout, which is reportedly being planned for two years from now.
"It will be myself against Tyson Fury in the coming year," Jake Paul said.
Size Difference
As Joshua and Paul participated in the customary face-off, with their size difference clearly visible, it drove home just how surprising this entire matchup is - and how amazing it is that the fight is really proceeding.
