Anthony Joshua will face Jake Paul in an eight-bout contest which will be broadcast live on Netflix.
Briton Anthony Joshua declared he will "dominate completely" Jake Paul and "defeat" his opponent as the pair met personally to promote next month's heavyweight fight.
Ex two-time world heavyweight champion Joshua meets YouTuber-turned-boxer Paul - in what is, on paper, a huge mismatch - at Miami's Kaseya Center on 19 December.
Boxer's Mindset
"I plan to break his face and damage his physique. I'm here to prove I'm superior," the British boxer, 35, declared.
"I'll stamp all over him. That's how fighters think.
"I intend to genuinely try to injure him. That's what I want to do."
Civil Exchange
Despite those words, a relaxed Joshua and social media star Jake Paul - usually famous for his theatrics - were respectful and kept it respectful with each other.
Paul instead criticized ex Joshua's opponent the Cameroonian fighter and called him "not serious" after Ngannou declined a fight offer.
Taking Aim at Fury
Anthony Joshua, meanwhile, targeted British opponent Tyson Fury - and rejected a million-pound wager 'The Gypsy King' states he will put on a victory for Paul.
"[Paul] outshines Tyson Fury - he showed up," Joshua commented.
"I give him credit for that."
Serious Fighter
Despite declaring he will hurt Jake Paul, Joshua declined to speak negatively about his opponent's boxing ability.
"Jake is a credible opponent," he said.
Jake Paul's Background
Jake Paul - who first rose to fame on the Disney Channel - has mostly fought mixed martial artists or faded names since becoming pro.
He lost to Briton Tommy Fury in last year.
Financial Attraction
Nevertheless, the relative newcomer is still one of the sport's largest financial successes, regularly earning substantial paydays.
Forecast and Belief
The 28 year old predicted a stoppage in round four or five and stated he would prevent the long-awaited Fury-Joshua bout, which is apparently being planned for two years from now.
"It's going to be me versus Tyson Fury next year," Jake Paul declared.
Physical Difference
As the two fighters participated in the usual stare-down, with their physical disparity evident, it emphasized just how surprising this entire matchup is - and how remarkable it is that the bout is really proceeding.
