UFC star Conor McGregor has told Floyd Mayweather he would be "dead in twenty seconds" if he fought the Irishman in a real fight.

He made the comments during the first leg of the press tour to hype their upcoming bout on August 26. The UFC uploaded video of the testy exchange (around the 9:09 mark) (warning: video contains NSFW language):

The two will come face-to-face four times during the press tour, which will travel from Los Angeles to Toronto, Brooklyn and London. 

As expected, the Notorious didn't hold back during the first stop in L.A., making numerous references to Mayweather's supposed tax problems. According to legal website Law360 (h/t ESPN.com's Darren Rovell), Money has asked for a reprieve on unpaid taxes from 2015 until after the fight.

Per radio presenter Michael Stets, Mayweather took the many references to heart:

While Money is the overwhelming favourite to win the bout?he has a perfect 49-0 record in the ring and has faced multiple future Hall of Famers, whereas McGregor has no professional boxing experience?most pundits would likely agree the Notorious would fare better in a "real fight."

The UFC lightweight champion has the fearsome power and standup game to go with solid ground work, even if he's better known for his knockouts. Whether that power will translate to the boxing ring remains to be seen.
