UFC double-champion McGregor and five-weight world boxing champion Mayweather came face to face for the first time on Tuesday as they began their promotional world tour ahead of their bout at the T-Mobile Arena on August 26.
The pay-per-view price for August's fight has been set at $89.95, which isn't cheap. Others are angered by the fact that McGregor, a man who has never competed in a professional boxing match, is taking on one of the very best boxers of this era.
McGregor, 28, was first to address the gathering of media and 11,000 fans.
The UFC star said:"He was trying to say something about the gloves and I was like "You cried about the gloves".
Mayweather retired from the sport of boxing with a flawless 49-0 mark, but McGregor doesn't appear to be fazed.
Since it was announced that McGregor will face Mayweather later next month, there has been some speculation as to whether the UFC's lightweight champ might retire. Not only did he call out Mayweather for wearing a track suit to the presser, McGregor went as far as to suggest the boxer couldn't even afford a real suit anymore.
Where is the fight being held?The outspoken Irishman made a prediction for their upcoming bout: He's going to knock Mayweather out inside of four rounds.
The 40-year-old Mayweather, who is coming out of retirement for the event, responded by mocking McGregor's relatively meager career earnings as compared to his own. McGregor thanked everyone for making this happen, but then turned to Mayweather and started trash talking. "I look good for a nine-figure fighter".
McGregor also gave an update on a potential return to the octagon. He's really connected with them, on social media and in person.
It's an allegation Mayweather was quick to deny - sharing an image of a $26 million tax bill on his Facebook page and insisting "my empire is rock solid and intact".
"I'm not the same fighter I was 21 years ago", Mayweather said in his MayMac World Tour press conference Tuesday in Los Angeles, via MMA Fighting. "Deep in my heart I know this is it".
"I don't care if it's a ring or it's an octagon, I will kick ass", he said.
