Conor McGregor has called out Charles Oliveira after he defeated Michael Chandler to become the new lightweight UFC champion.
The Brazilian extended his winning streak to nine in Texas with a dramatic second round TKO over the three-time Bellator champion.
And not long after the fight had been concluded McGregor took to social media to provide his views.
McGregor tweeted: "Congrats to Oliveira on becoming the 11th UFC lightweight champion. Wonder who Twelve is..."
Oliveira reacted to this provocation by responding to The Notorious via reporters, saying: "Conor, since you're so tough, first beat Dustin, then come to Brazil and I'll put you on your a**.
"He's just one of these guys that talks a lot. He needs to beat Dustin first."
Dustin Poirier himself, meanwhile, sent a classy message, saying: "Congratulations @CharlesDoBronxs, you earned that the hard way! Head up @MikeChandlerMMA highest of the highs and lowest of the lows."
Speaking after the clash Oliveira said: "I told you I was going to knock him out, and I came and knocked him out.
"I'm proving to everybody, I'm the lion of lions.
"Michael, you're a great champion, but today was my day. Michael said I couldn't take pressure, and he hit, hit, hit. And I'm still here. Here's the belt!"
Reacting to his defeat, meanwhile, Chandler said: "We saw one of the toughest dudes on the planet come back from some adversity - Charles Oliveira is the real deal.
"I take nothing away from him. I will be back. I promise you I'm going to win that UFC strap within the next 12 months. This was a great opportunity. I thank the UFC for this opportunity.
"Charles Oliveira showed how he's a consummate professional. He's showed up for the last 10, 11 years here inside the UFC octagon.
"We'll get this one back. We're gonna run this one back, eventually."
