McGregor – who is showing off his training in the post – hinted that he has the upper hand as Mayweather has only ever trained in one style of fighting.

McGregor said via his Instagram: “Myself and @sbgcharlestown [SBG Charlestown Gym] have been working together on unrestricted, unarmed fighting, since we are kid.

“Not much will change when I fight under the famed, yet very limited, Queensbury rules.

“No disrespect to single discipline fighters, from boxing to kicking to grappling, just know that understanding one style of fighting is simply not enough.

As the super fight draws closer by the day, McGregor’s striking coach Owen Roddy says they have started training already – but a deal is not done yet.

Roddy told The Mac Life: “We did a little bit a week or two ago, but training officially starts hard now when I get back on Tuesday.

“I was talking to Conor over the weekend and we’re getting going.
