There’s one thing that Conor McGregor can ever be accused of, it’s lacking in confidence. 

Even in the face of Floyd Mayweather, a man who has never been defeated, McGregor has no qualms of continuing his career streak of bold statements. Today at the Grand Arrival event, hosted to kick off the fight week festivities, McGregor was greeted by a media scrum.

Immediately, he put to bed Mayweather’s recent comments about McGregor struggling in training to make fight weight.

“[He should] shut his fucking mouth,” McGregor said. “He knows nothing. He’s praying. Praying for weight, praying for fatigue, praying for me to take a back step. But all he’s doing is praying — he’s praying to the new god of boxing.”

Recently, Mayweather has promoted the fight by saying he owes fans following a disappointing performance against Manny Pacquiao in 2015, and promises to come out aggressively from the first bell.

McGregor, typically, remains unfazed.

“I’m not really worried about what way he’s starting,” he said. “I know I’m starting extremely fast, I’m going to come forward and bust him up. I believe I’ll knock him out early. I believe one or two rounds. 8-ounce gloves I don’t see him surviving. I don’t care if he catches it on the glove either, I’ll flatten him through the glove. After that, I’m starting to think I will toy with him after he goes down.

“See, in mixed martial arts, you get to step past the legs and pound the head, and stiffen the body. Boxing’s a little bit different where there’s a referee to stop me following up. So there will be 8 to 10 seconds to recover — if he recovers. I may decide to toy with him in there after that. I will have the ability to put him away inside two rounds.”
