Conor McGregor says he OWES Nate Diaz a third fight — purely out of respect — and states definitively, “The trilogy will happen.”

McGregor was standing on the bar at Binny’s Beverage Depot in Chicago when he told a bunch of his fans why the rubber match NEEDS to happen. TMZ Sports has the video.

“He fought me, he beat me. He gave me a rematch at the exact same weight, there was no hesitation, that’s a true fighter right there,” McGregor said.

“I have nothing but respect … I owe him the trilogy now and the trilogy will happen.”
