Floyd Mayweather has claimed that he is the greatest boxer of all time, arguing that he ought to be rated ahead of the iconic Muhammad Ali.

The former five-weight world champion has previously left Ali off his top five list, and opted to pick apart Ali's resume in order to prove his point.

Speaking to Shannon Sharpe on Club Shay Shay, Mayweather stated that 'The Louisville Lip' did not deserve to be recognised as the best to lace up a pair of gloves due to his defeat to the inexperienced Leon Spinks, whilst he also believes that Ali benefitted from two hotly-disputed decision victories in his trilogy of contests with Ken Norton.

"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," he said.

Mayweather was not done there, explaining why he should be ranked ahead of fellow undefeated champion Rocky Marciano. The hard-hitting heavyweight retired with a perfect 49-0 record, but Mayweather feels that the calibre of opponents that he faced puts him above Marciano when their careers are compared.

"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," he added.

Mayweather has not fought professionally since 2017, but is never too far from the spotlight, and is rumoured to be in talks to take on YouTube sensation Logan Paul in an exhibition contest.

The 43-year-old is also keen to remain in boxing in a coaching capacity, and has offered to help Deontay Wilder prepare for his third fight with Tyson Fury.

"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," said Mayweather.
