The Irish fighter will step into the ring at the famous Madison Square Garden marking the first time the UFC has held an event in the US state after laws were lifted earlier this year.

Standing on the basketball court of the iconic New York venue, a typically cocky McGregor took a pot shot from the three-point line, which he sunk, before declaring himself and immortal in waiting.

“Saturday night, I become immortal,” McGregor said to the crowd.

“I’m immortalised in this, I get the second belt, raise it up, never been done before. It means absolutely everything to me.

“This is my life’s work, so I’m ready, I’m going to be prepared. I’m ready to put a show on for the fans.”

When pressed on how he would down Alvarez, McGregor refused to give away his tactics.

“I feel like I can do it in many ways, I can paint many pictures in my mind, in many different styles,” McGregor said.

“All you’ve got to do is look at my previous fights. Every fight is different, every shot, every approach is different. That’s why they can’t figure me out. Be here for a treat.

“One round. “KO.”
