Conor McGregor still isn’t 100 percent sure who he’ll be fighting in UFC 189, but that hasn’t shaken his confidence.

The Irish fighter is scheduled to take on featherweight champion Jose Aldo on July 11 in Las Vegas, but Aldo’s bruised rib could put the fight in jeopardy. That didn’t stop McGregor from predicting on ESPN’s “SportsCenter” on Monday that he’d knock out the champ in just four minutes.

And although McGregor’s assertion is bold, he believes his attitude is a huge part of his success.

“In a business way, you must be confident,” McGregor said. “If you have any doubts, they will come back and play against you, so I am supremely confident. And as well, I feel I’m confident in my work ethic, my approach to the game, my nonstop effort to get better as a martial artist. I don’t feel that nobody else in the game is doing what I’m doing or is moving the way I am moving.”
