Anthony Joshua prepares to battle the American YouTuber in an eight-bout match which will be broadcast live on Netflix.
Briton Anthony Joshua declared he will "overwhelm entirely" Jake Paul and "break" the American as the combatants confronted each other to build hype for next month's heavyweight fight.
Former two-time world boxing king Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, theoretically, a mammoth uneven pairing - at Miami's arena on 19 December.
"I plan to break his face and break his body up. I aim to demonstrate I'm the better fighter," the British boxer, 35 years old, stated.
"I plan to overwhelm him. That's a fighter's mentality.
"I will genuinely try to cause him pain. That's my intention."
Despite those words, a calm Anthony Joshua and internet personality Paul - typically known for his theatrics - shared friendly words and maintained decorum with each other.
Paul instead criticized ex Joshua rival Francis Ngannou and called him "a joke" after the Cameroonian declined a bout proposal.
Joshua, meanwhile, criticized British opponent Fury - and rejected a £1m bet 'Tyson Fury' says he will place on a victory for Paul.
"[Paul] outshines Fury - he's actually sitting here," Joshua stated.
"I acknowledge that."
In spite of declaring he will damage his opponent, Anthony Joshua chose not to speak negatively about his rival's boxing ability.
"Jake is a legitimate boxer," he remarked.
Jake Paul - who originally gained popularity on the Disney Channel - has primarily boxed MMA fighters or declining opponents since turning professional.
He was defeated by British fighter Tommy Fury in last year.
Nevertheless, the inexperienced fighter is still one of boxing's greatest money-making draws, frequently receiving massive paydays.
The 28-year-old predicted a KO victory in round four or five and claimed he would derail the much-anticipated Fury-Joshua bout, which is allegedly being planned for two years from now.
"The next fight will be my match with Fury next year," Paul declared.
As Joshua and Paul engaged in the customary confrontation, with their height and weight contrast clearly visible, it emphasized just how improbable this complete situation is - and how remarkable it is that the bout is truly proceeding.
