The boxing icon returned to the ring for the first time since 2017 for an exhibition bout with YouTube star Logan Paul but failed to knock out his opponent and suggested that it was simply "legalised bank-robbing".
Mayweather said: "It wasn’t a real fight, it was like sparring in the gym.
"I could have pressed real, real hard and thrown some crazy combinations… his goal was to survive and that was a win for him."
"When it comes to legalised bank robbing, I’m the best."
Mayweather also stated that the fight in Miami would "probably" be his last bout.
He said: "As far as me fighting again, absolutely not. As far as me doing another exhibition, probably not."
Mayweather was unable to land a killer blow against the social media star and admits that he was impressed with how Paul coped in the ring having only ever boxed once.
He told Showtime Sport: "I had fun. You've got to realise I'm not 21 anymore.
"But it's good to move around with these young guys. Test my skills. Just to have some fun.
"A great young fighter. Strong, tough. He's better than I thought he was.
"He's a tough, rough competitor. It was good action.
"I was surprised by him tonight. A good guy.
"Even though he doesn't have much experience, he knew how to use his weight and he knew how to tie me up tonight."
