Conor McGregor has vowed to “shock the goddamn world” as his much-anticipated face off with Floyd Mayweather edges ever closer.

The UFC superstar is tipped to swap the Octagon for a ring to take on the undefeated Mayweather with both fighters engaged in a feisty war of words for some time.

While the clash is yet to be officially sanctioned McGregor, a double world champion in UFC, has given his clearest indication yet that it will go ahead before declaring he will do what no one has ever done before and stop the 49-0 Money Man.

“You're the boxing guy? I'm the boxing guy. Watch me take over boxing,” he said after watching compatriot Michael Conlan win on his professional debut at Madison Square Garden in New York.

“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 as a m**********r, 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.”

Last weekend Mayweather confirmed he was officially “out of retirement” to take on the Irishman while UFC president Dana White this week admitted he believes that, despite a number of remaining obstacles, the fight will go ahead.
