Speculation surrounding a rematch between the two combat icons began last month, with reports suggesting the duo were in talks for a clash that could be worth up to £830 million. Amid the rumours, McGregor took to Instagram to share a photo from their first fight five years ago with the caption: “I accept.

Their first bout, which was held in Las Vegas, became the second-highest pay-per-view in fighting history after attracting about four million viewers. Mayweather went 50-0 with the tenth-round stoppage of the Dubliner, making around £250 million while McGregor secured £100 million. 

Mayweather’s victory against The Notorious proved to be his last ever pro fight, but he has since fought in various exhibition matches. He faced Tenshin Nasukawa in 2018 and went the distance with YouTuber Logan Paul in 2018.
