Despite never winning a fight, Logan Paul is talking a great one, ahead of his eight-round exhibition with Floyd Mayweather at the Hard Rock Stadium in Miami on Sunday evening.

The YouTube celebrity is 0-1 as a professional, but will enjoy a 34.5lbs weight advantage as well as significant edges in height and reach in what amounts to a fight between a novice cruiserweight and an elite super-welterweight in his mid-40s.

Boxing purists won’t be watching, but a new demographic of fans will be transfixed, with significant Pay-Per-View numbers predicted for the high-profile novelty bout. 

Paul says he is ready to shock the world and stop Mayweather in a bout that will have no decision should it go the full eight-round distance.

“He’s not ready, he don’t know what to expect, and this is not the biggest fight of my life,” Paul told Showtime Sport.

“This is the biggest fight of his life because he’s got a lot on the line and he’s got everything to lose. I’m going to go in there, have fun.

“Tomorrow I break the simulation and beat the greatest boxer in the history of the planet. I’m going to get it done. Floyd is not ready, that’s all I can say.”

Mayweather, arguably the greatest fighter of the modern era, is naturally undaunted by the prospect.

“I’ve been here before, so I know what it takes,” he told Showtime Sport. “I’ve fought every different style you can possibly fight. Height don’t win fights, weight don’t win fights, fighting wins fights at the end of the day and I can fight.
