Floyd Mayweather has described himself as the greatest boxer while taking a swipe at Muhammad Ali.
Mayweather retired in 2017 with a record of 50 wins and no loss.
His last fight was against UFC Mixed Martial Arts fighter, Conor McGregor.
He told ESPN: ‘He’s beat more world champions than any other fighter in a shorter time and less fights than any other fighter.
‘Landed punches at the highest percentage and took less punishment. He’s been world champion 18 years in five different weight divisions.’
Speaking of Ali, he said: ‘Ali, only one weight class and really lost to Ken Norton three times. What he did is he stood for a cause in an era when African-Americans didn’t stand up for their people.
‘What are we judging fighters on? Because if we’re judging fighters on standing for a cause, then it’s Ali hands down. But if we’re talking about taking the least punishment and breaking records, it’s Floyd Mayweather.
‘Muhammad Ali paved the way for me to be where I’m at today, he’s a legend. But when we talk about record-breaking, we’ve got to talk about Ali losing his world title to a fighter with only seven fights.
‘I have to take my hat off to Ali, but I didn’t give this sport 40 years to say that there’s another fighter better than me. What I’m here to teach fighters is this: the name of the game is to hit and not get hit. It’s not about taking punishment.
