Mayweather, 45, claimed on Wednesday he is in talks with the UFC superstar to stage another fight in 2023 following their money-spinning showdown five years ago.
The five-weight world champion will take on Japanese MMA star Mikuru Asakura this weekend with McGregor in his plans for next year.
‘I want to go out there this weekend and have fun [against Mikuru Asakura]. Then I have another exhibition Dubai in November and me and Conor McGregor in 2023,’ Mayweather told The Daily Mail.
‘We don’t know if it’s going to be an exhibition of a real fight. But there’s been talks of both. I would prefer an exhibition.’
McGregor has poured cold water on those plans, sharing an image of their 2017 fight on Instagram with the caption ‘#notinteresed’.
McGregor is nearing the end of his recovery from a broken leg suffered in his trilogy fight against Dustin Poirier last July.
The 34-year-old has lost three of his last four fights in the Octagon with his return – in MMA or boxing – pushed until 2023 as he prepares for his Hollywood debut, starring alongside Jake Gyllenhall in a remake of the classic movie Road House.
But the Dubliner’s drive to succeed has not wavered, according to his manager and business partner Audie Attar.
‘First and foremost, he loves this sport,’ Attar told MMA Junkie. ‘I think that’s the one thing that’s very special about him.
‘It’s why it’s allowed him to reach a level of success that most fighters aspire to achieve. He loves it. The second part is he’s a competitor.
‘Does he have more ambitions and goals that he wants to achieve? Absolutely.
‘I think that’s what makes it so special and so intriguing and it’s going to be an interesting story, and I do believe it’s going to be the greatest comeback in sports history.’
