Holloway (22-6 MMA, 18-6 UFC) said both before and after his all-time performance against Calvin Kattar at UFC on ABC 1 this past Saturday that he was highly interested in running it back with McGregor. His record output in the fight caught McGregor’s (22-4 MMA, 10-2 UFC) attention, and the former two-division champ expressed interest in the bout.

“I thought it was a solid performance,” McGregor told The Mac Life. “He fought an up-and-comer; he did well. I was actually doing an interview and he skateboarded by the window. I was like, ‘Is that Max Holloway?’ He’s obviously hanging around, and fair play to him. He’s definitely in the pipeline for a bout against me. I would happily rematch Max, and after a performance like that, he’s put himself right up there.”

McGregor, who rematches Dustin Poirier in the main event of UFC 257 on Saturday in Abu Dhabi, said an encounter with Holloway would have different circumstances than the first fight, which took place in August 2013. McGregor won that fight by unanimous decision in the featherweight division. But McGregor said this one would have to be at lightweight.

“He’s a tall lad,” McGregor said. “He’s taller than me, so he could build up. He’s only fought at 155 once. It was against Dustin. He was a bit out-powered, but he could certainly do it. Against other lightweights? You never know. But the rematch would be 155, for sure.”

Holloway said in the midst of his fight against Kattar that he was the best boxer in the UFC. McGregor, who has professional boxing experience in the form of a fight against Floyd Mayweather, found that notion to be rather comical, and said he’ll show why at UFC 257.

“He’s not the best boxer,” McGregor said. “It’s no question, and I’ll prove that on (Saturday). Let’s see what he says Sunday morning.”
