, Tyson said: "Floyd is going to kill this guy, man.
"Floyd stays in the gym, he's never out of shape. He's going to have so much fun winning this money."
The 44-year-old, who won world titles in six weight classes during his illustrious career, hasn't lost a fight since the 1996 Olympics - and even that was a controversial defeat.
But Paul, who lost his only professional fight to fellow YouTuber KSI in November 2019, is SIX inches taller than his opponent - and is likely to be much heavier as a result.
And, at 26, the wannabe is 18 years younger than Mayweather - giving him another crucial advantage.
Paul certainly fancies his chances, promising to 'decapitate' his distinguished rival in the first round of their scrap.

And his brother Jake, who has also ventured from YouTube into boxing, believes the underdog has a chance.
He told SunSport: "This is entertaining and I think that Floyd will again severely underestimate my brother, and there's a size advantage, my brother's fast and has knockout power."
Jean Pascal, who's trained the Paul brothers, has also praised Logan's boxing skills.
He told SunSport: "Definitely he's going to surprise people, honestly what people don't know, they think Logan Paul is just a YouTuber, but Logan Paul has got some skills."
But Mayweather's ex-sparring partner Ashley Theophane is having none of it and reckons the former champ will win ease.
He told SunSport: "Floyd will win by knockout. It’s an exhibition but you have a YouTuber vs a legendary boxer.
"Floyd will take Logan Paul out within four rounds then Jake Paul can get his turn."
The eagerly-anticipated fight will take place in Miami on Sunday, June 6 at 4am UK time.
