"They say, ‘It’s not all about the money.’ Well, your kids can’t eat legacy," Mayweather said. "Patches on my trunks, that was $30 million alone. So, who’s really the smartest one in the sport of boxing?"

The 44-year-old Mayweather used the ring skills that propelled him to world titles in five divisions and a 50-0 career record to frustrate Paul with a solid lead and counter shots.

Mayweather, who won titles in the super-featherweight, lightweight, super-lightweight, welterweight and super-welterweight divisions, said he will not return to competitive boxing. 

He added that he will continue to do pay-per-view events, and if fans don’t like it he said they shouldn’t come or watch.

"When it comes to legalized bank robbing, I’m the best," Mayweather said. "I don’t care if you write good stories, I don’t care if you write bad stories, at the end of the day, I will always have the last laugh.

"When I see there’s a chance for me to do a heist. A quick heist. At the end of the day, I’m the smart one. They said, ‘Floyd don’t look good like he used to look.’ My bank account is looking better and better each and every day."
