Conor McGregor has vowed to "shock the whole goddamn world" by stopping Floyd Mayweather should the pair meet in a proposed showdown this summer.
Speculation that UFC star McGregor and retired five-weight world champion Mayweather could meet under Queensbury rules has been growing on a daily basis.
Mayweather announced last week that he was "officially coming out of retirement" to take on McGregor and UFC president Dana White admitted on Thursday there was "too much money at stake" for a fight between the pair not to happen.
'Notorious' talked up the clash further on Friday night when he turned up to support fellow Irishman Michael Conlon as the former Olympian made a winning debut in the paid ranks at the Theater Madison Square Garden.
Conlon made up for his heartache in Rio last summer, where he suffered a controversial quarter-final exit, with a three-round stoppage of Tim Ibarra, but it was McGregor who stole the limelight.

"I'm the boxing guy. Watch me take over boxing," bellowed McGregor to the assembled media ringside.
"Trust me on that. No one in this boxing game knows what's coming. Trust me on that. When I step in there, I'm going to shock the whole goddamn world. Trust me on that.
"Look me in the eyes. Twenty-eight years of age, confident, long, rangy, dangerous with every hand. Trust me, I'm going to stop Floyd and you're all going to eat your words.
"The whole world is going to eat their words."
When pushed as to when the fight is likely happen, he added: "'We're getting close. You'll hear about it."
