The American is set for a shock return to the ring on May 14 in an eight-round contest against Don Moore on the helipad on top of the Burj Al Arab Hotel in Dubai.
Mayweather, confirmed he would never fight professionally again after defeating Conor McGregor in 2017 to extend his unbeaten record to 50-0.
The 45-year-old's fight against the UFC star generated 4.3 million pay-per-view buys - only his fight against Manny Pacquiao has sold more in America at 4.5 million.
Mayweather was taken the distance against Paul despite landing the cleaner, harder hitting shots.
"TBE" complimented Paul's efforts but confirmed it was highly unlikely that he would fight again.
"I had fun. You've got to realise I'm not 21 anymore," he told Showtime Sport. "A great young fighter. Strong, tough. He's better than I thought he was.
"We don't know what the future holds, but I'll talk it over with my team, and see where we go from there.
"You've got to realise, I've been in this sport 25 years. I understand I'm not 21, I'm not 25, but I had fun tonight."
Mayweather's return is part of an event being labelled as 'The Global Titan Fight Series'.
The undercard will include Mayweather Promotions' former two-division world champion Badou Jack and ex-UFC titlist Anderson Silva.
'Money's' opponent Moore, is 42 years old and is a former professional boxer who fought 19 times, winning 18 of them.
