Conor McGregor has vowed to 'bust up' Dustin Poirier in their UFC 257 bout this weekend.
The Notorious gets in the octagon for the first time in over a year in the early hours of Sunday morning to face the American, who he defeated at featherweight in 2014.
McGregor admits he has huge respect for his opponent, but believes the lightweight bout will last less than 60 seconds.
He told BT Sport: "There is respect for sure. How can you not respect how he handled that loss and where he has gone in his life; a lot of admiration for the man.
"I am gonna bust him up but. There's no doubts about it. There's no ifs, ands, and buts, he is getting bust up. But, it's nothing but respect."
The former two-weight champion added: "I'm going to put on a flawless performance, an absolute clinic.
"I'm confident in all ranges. I've never been more confident in my endurance than I have been now.
" I know Dustin and his team may take a bit of disrespect from me, saying I'm going to knock him out in 60 seconds. Well, it works both ways, you know?
"[They are going to] say, 'oh, the conditioning thing.' We'll see about that if you can last through the trauma that I'm going to bring to you, you know what I mean?
"We'll see what you're about, who has the endurance, and what is what.
"So, I'm excited all across the board. I'm confident. All my skills are on fire at the minute, you know?
"Pinpoint precision, my kicks, my punches, my knees, my wrestling, my grappling, my clinch, putting it on whatever. I'm ready."
