Mayweather Promotions CEO Leonard Ellerbe has made it clear that if Conor McGregor is serious about wanting a rematch against Floyd Mayweather Jr, "all he needs to do is call."
McGregor swapped the MMA cage for the boxing ring back in 2017 to face, who many would argue as the greatest boxer of all time, in what was then touted as the biggest fight in history.
After a promising start at the T-Mobile Arena in Las Vegas, the 'now-retired' UFC great ultimately ran out of gas and had to be stopped by the referee in round 10.
Two years on, however, and he's confident he can deliver Mayweather his first ever professional defeat.
"I would like to rematch him under boxing rules, again. And I believe I would win. Actually, there I go again with that fake humbleness. I know I would win.

"When I went into the fight in the early rounds I was whooping him in the early rounds. I went back to my corner after the first round and I said, ‘This is easy!'"
Ellerbe - who is at the steering wheel of Mayweather's boxing business - has played a big role in many of the company's large events, including the McGregor and Manny Pacquiao bouts.
When asked by TMZ Sports about his thoughts on McGregor's recent comments, Ellerbe was more than prepared to set the ball rolling for a potential rematch.
"Conor McGregor knows he's always welcome to that ass whooping.
"If Conor wants some of that smoke again, he knows what he's gotta do. [But] if you're asking me, I think Floyd would oblige to that ass whooping."
He did state, however, that he hadn't discussed a return to the ring for the 50-0-0 legend, but, realistically, believes Mayweather wouldn't refuse another nine-figure pay-out.
Both fighters have walked away from their respective sports since the memorable fight, with McGregor bowing out of MMA after losing to Khabib Nurmagomedov at UFC 229 last year.
However, knowing what the Irishman is like, that could be all for publicity.
