Anthony Joshua is set to fight Jake Paul in an eight-round contest which will be broadcast live on Netflix.
Briton Joshua said he will "dominate completely" the American and "break" the American as the pair came face-to-face to promote next month's boxing match.
Ex two time unified heavyweight champion Joshua meets YouTuber-turned-boxer Paul - in what is, theoretically, a massive uneven pairing - at Miami's Kaseya Center on 19 December.
Boxer's Mindset
"I will damage his features and damage his physique. I'm here to prove I'm the better fighter," Joshua, 35 years old, stated.
"I'll stamp all over him. That's the boxer's mindset.
"I intend to genuinely try to hurt him. That's my goal."
Respectful Exchange
In spite of those words, a relaxed Joshua and internet personality Jake Paul - normally known for his theatrics - shared friendly words and kept it respectful with each other.
Paul instead criticized ex Joshua opponent Francis Ngannou and labeled him "ridiculous" after the Cameroonian turned down a bout proposal.
Targeting Tyson Fury
Anthony Joshua, at the same time, criticized UK rival Tyson Fury - and refused a million-pound wager 'The Gypsy King' states he will put on a Paul win.
"Jake Paul outshines Tyson Fury - he's present here," the boxer said.
"I acknowledge that."
Serious Fighter
In spite of saying he intends to punish Paul, Joshua declined to speak negatively about his opponent's fighting skills.
"Jake Paul is a legitimate boxer," he said.
Paul's History
Paul - who originally gained popularity on the Disney Channel - has primarily fought mixed martial artists or declining opponents since turning professional.
He lost to Briton Fury in last year.
Commercial Success
Nevertheless, the inexperienced fighter continues to be one of the sport's largest commercial attractions, regularly earning huge earnings.
Forecast and Confidence
The 28-year-old predicted a KO victory in rounds four or five and stated he would prevent the much-anticipated Fury-Joshua bout, which is apparently under discussion for two years from now.
"It's going to be me versus Tyson Fury next year," Jake Paul declared.
Physical Disparity
As Joshua and Paul participated in the usual confrontation, with their physical disparity evident, it highlighted just how improbable this whole event is - and how remarkable it is that the bout is truly happening.
