And "Notorious" was all ears.

McGregor took to his Twitter account after watching Chandler obliterate Tony Ferguson via a second-round knockout (front kick), which was later followed by Oliveira's first-round submission (rear-naked choke) of Justin Gaethje in the main event.

Before a victorious Oliveira left the Octagon, he made sure that he stated through an interpreter: "Hey, Conor McGregor — you coming up or you're going to run away?"

McGregor's response:

At the onset of the UFC 274 main event, Oliveira had to vacate the lightweight title after failing to make weight Friday. However, with the big win over Gaethje, Oliveira is now the No. 1 contender for the championship.

McGregor also took the time to address Chandler's challenge.

That was in reference to Chandler's fiery callout of the Irish superstar. Earlier in the night, Chandler said that if he doesn't get the winner of Oliveira-Gaethje that he'd be willing to move up to 170 pounds to make the McGregor tilt happen.

UFC president Dana White addressed the possibility of the latter matchup during the UFC 274 post-fight press conference.

"Yeah, that's a fun one, man," White said of the prospects of pairing McGregor and Chandler together in the Octagon someday. "Who the hell wouldn't want to see that fight? But Conor is not ready yet, so Conor is hurt. When Conor is 100 percent and can actually really start training for a fight, then we talk about what's next for Conor. But listen ... who doesn't want to see Chandler vs. Conor? Raise your hand."
