Jake Paul plans to "shock the world" and "pull off the biggest upset in sports history" when he takes on former two-time world heavyweight champion Anthony Joshua in Miami.
YouTuber-turned-boxer Paul - who has a 12-1 record as a pro and beat ex-middleweight world champion Julio César Chávez Jr in his previous fight in June - will meet Joshua in an eight-rounder on Friday.
The American said at a public workout: "One of us is going to sleep - that's what we're going to do here. That's what this heavyweight fight is all about.
"I started my boxing journey here in Miami. We're bringing it back and I'm going to shock the world and pull off the biggest upset in sports history."
Joshua, who held the unified world heavyweight title from 2017 to 2019 and again from 2019 to 2021, said: "It was an honour to be invited to America.
"To come and perform in front of some amazing people, the Miami crowd, the international crowd. So I just said: 'It's got to be done.' I got to give him [Paul] respect, because I'm f*****g ready."

"Anybody who I talk to about boxing that's the one thing they always mention - 'When are these two getting it on? Are they ever going to get it on? We never got to see it.'
"I think it will happen and when it does happen I think it's going to be massive."
