Conor McGregor warns Floyd Mayweather only Bruce Lee could prepare him for their fight

: "What other mixed martial artist is there like me? He’d need to reincarnate Bruce Lee, and that would be the only person he could bring in that could mimic me with the way that I’m coming at him.

";I am not like any other mixed martial artist. I am not like any other boxer. I am in a league of my own, and I’ll prove that August 26."

McGregor - or Mystic Mac - predicts he will KO Mayweather in the second round.

And he insists he is ready for the performance of his lifetime in what will be a revolutionary fight.

He said: "Everything has been absolutely perfect.

"We're ready to go to put on the performance of a lifetime, of my lifetime - of my team's lifetime and we're ready to go and change the face of the fight game once again."

On his preparation for the mega-fight, McGregor said: "I've taken this very seriously, no stone has been left unturned.
