If two blockbuster bouts were not enough, the trilogy is coming.
Conor McGregor gained revenge over Nate Diaz in Saturday's rematch at UFC 202 in Las Vegas, returning to winning ways via a points decision - 48-47 47-47 48-47 - following March's shock result.
And after outlasting Diaz in a bloodied and energy-sapping fight, which went the full five rounds, Irish star McGregor quickly turned his attention to a third showdown.
"Surprise, surprise mother f*****, the king is back," undisputed UFC featherweight champion McGregor said afterwards.
"I proved the class difference. It was a hell of a fight, he is a hell of a competitor.
"I came up to 170, faced the bigger man and overcame my adversity. It's 1-1, let's do it again. If you want this trilogy it's on my terms. Come down to 155 and we'll do it."
Split open with his face covered in blood, having been sent to the canvas on three occasions inside the opening two rounds, American Diaz also called for another rematch.
"I want number three," Diaz added. "I gave him number two. Lets go again.
"Good job today Conor but we going for three, for real. Until then I ain't coming back."
