As Conor McGregor prepares to put a bow on his trilogy with Dustin Poirier at UFC 264 on Saturday, the Notorious One is also looking at a third fight with another opponent.
Speaking to reporters on Thursday, McGregor said a trilogy fight with Nate Diaz "must happen."
"I look forward to the day," he added.
After fighting at lightweight for his entire UFC career, McGregor agreed to move up to middleweight in 2016 for a bout with Diaz.
Diaz came out on top in the first match at UFC 196 by submitting McGregor in the second round.
