The 43-year-old – who failed to name Ali in his top five list in July – revealed he has ‘accomplished’ more than any other fighter.
And he even left off the former Olympic gold medallist from his boxing ‘Mount Rushmore’.
Mayweather retired in 2017 following his win against Conor McGregor with a record of 50-0 – winning 15 world titles across five weight divisions.
Speaking to Club Shay Shay about boxing’s legendary fighters, he said: “Out of all these guys in the history of boxing, I have accomplished more than every fighter in the history of boxing.
“How many world champions have Rocky Marciano beat? So we already know, I beat more champions that’s going in the hall of fame.”

Mayweather then turned his attention to Ali, where he insisted he cannot be No1 as he lost to an inexperienced Leon Spinks, while also commenting on his trilogy against Ken Norton.
Despite beating Norton twice after losing in their first meeting, Mayweather believes Ali got two fortunate decision victories.
He added: “Is Ali the same fighter that got beat by a fighter with seven fights? Leon Spinks beat Muhammad Ali when he only had seven fights.
“What’s the heavyweight guy that Ali fought three times, Ken Norton? Ken Norton really beat Ali three times, go back and look at the fights.”
The 1996 Olympic bronze medallist finished off by saying: “Floyd Mayweather is still the face of boxing.
“Every time boxing comes on, you don’t bring up Muhammad Ali’s name, you don’t bring up Mike Tyson’s name, you always bring up Floyd Mayweather’s name.”
Mayweather – who is in talks to face YouTuber Logan Paul in an exhibition bout – has offered to train Deontay Wilder for his trilogy bout against Tyson Fury.
Speaking of the Bronze Bomber, he said: “Tyson Fury’s solid, he’s got skills.
“Deontay Wilder’s got bombs, but we can make his skills a lot better.
“I’m here to help fighters, even Wilder.
“I’m here, all he’s gotta do is let me know what he wanna do and we can make it happen.”
