The British boxer will face the American YouTuber in an eight-round contest which will be shown live on Netflix.
British boxer Joshua declared he will "dominate completely" Jake Paul and "break" his opponent as the two fighters came face-to-face to publicize next month's heavyweight fight.
Former two-time unified title holder Anthony Joshua faces social media star turned fighter Jake Paul - in what is, theoretically, a huge uneven pairing - at Miami's venue on December 19th.
Fighter's Mentality
"I'm going to damage his features and break his body up. I'm here to prove I'm the better fighter," Joshua, 35 years old, declared.
"I'll stamp all over him. That's the boxer's mindset.
"I intend to genuinely try to hurt him. That's my goal."
Civil Interaction
In spite of such comments, a calm Anthony Joshua and social media star Jake Paul - usually famous for his theatrics - were respectful and kept it respectful with each other.
Jake Paul rather targeted former Joshua rival Francis Ngannou and called him "ridiculous" after the Cameroonian declined a match opportunity.
Targeting Fury
Anthony Joshua, meanwhile, took aim at British rival Fury - and refused a £1m bet 'The Gypsy King' says he will place on a victory for Paul.
"Jake Paul is superior to Fury - he's present here," Joshua commented.
"I acknowledge that."
Serious Fighter
In spite of declaring he will damage his opponent, Joshua refused to comment unfavorably about his rival's boxing ability.
"Jake is a serious fighter," he remarked.
Jake Paul's Background
Jake Paul - who first rose to fame on the television network - has primarily boxed MMA fighters or past-their-prime fighters since entering professional boxing.
He lost to Briton Fury in last year.
Financial Success
However, the relative newcomer continues to be one of boxing's biggest financial successes, frequently receiving huge paydays.
Prediction and Confidence
The 28-year-old anticipated a knockout win in the fourth or fifth round and stated he would stop the much-anticipated match between Joshua and Fury, which is apparently under discussion for two years from now.
"It's going to be my match with Fury in the coming year," Paul declared.
Size Difference
As both boxers met for the usual stare-down, with their size difference evident, it emphasized just how improbable this whole event is - and how astonishing it is that the match is actually proceeding.
