YouTube sensation Logan Paul insists 'nothing is impossible' ahead of his major exhibition bout against undefeated legend Floyd Mayweather.
The 26-year-old will take on Mayweather, 44, at the Hard Rock Stadium in Miami this weekend.
The bout looks set to be a huge PPV event following months of teasing from the two fighters.
Speaking to reporters at a pre-fight event, Paul said: "It's not an exhibition. What exhibition is eight three-minute rounds? This is a fight.
"He's trying to make an example of the big brother, so the younger brother [Jake Paul] has to suffer and watch. I don't know if you've seen 'Scarface', but that's what he's trying to do.
"This is going to be a war. I'm not going to make s*** easy for him. We've been training for eight months now, preparing to fight this guy."
Paul has only fought professionally once, in August 2018 against fellow YouTuber KSI. The American lost via split-decision.
He added: "I'm 30 pounds heavier, six or seven inches taller. Half his age and I'm hungry - I've got nothing to lose.
"I'm going in there with that energy, and he's got everything to lose.
"It's a fight, so anything can happen."
Mayweather retired from the world title scene with a stunning record of 49-0 (26 KOs) in 2015. He won championships at welterweight, lightweight and super featherweight during a glittering career.
'Money' has focused on lucrative crossover bouts since then. In 2017, he took his record to 50-0 with a TKO victory over UFC star Conor McGregor.
Paul v Mayweather is available on Sky Sports Box Office from midnight on Sunday.
