Floyd Mayweather and Conor McGregor faced-off Tuesday in Los Angeles at their press conference ahead of their Aug. 26 megafight in Las Vegas.
McGregor guaranteed he would knock Mayweather out within four rounds.
"I don't fear him, I don't fear his limited set," McGregor said. "This isn't a true fight. If this was a true fight, it wouldn't take one round."
"He's in a f--king track suit, he can't even afford a suit anymore," McGregor said.
"I'm the A-side," Mayweather said. "That's why this b---h had to come to the boxing ring."
"He looks good for a seven-figure fighter; he looks good for an eight-figure fighter, but motherf--ker, I'm a nine-figure fighter," Mayweather added.
