The Irishman is the 6/1 underdog, with Mayweather available at 1/10 to notch his 50th victory when they face off.

Asked about a potential mega-bout between the pair spokesperson Paddy Power, said “What started as a crazy idea now looks very much a reality.

“As an experienced boxer it’s hardly surprising that Mayweather is the favourite, but current betting trends would suggest that our punters believe that McGregor is in with a great chance of causing an upset.”
