In MMA, when you talk as much trash as UFC featherweight champ Conor McGregor, it’s a given that your words will come back to bite you when you eventually lose.

McGregor recently suffered his first UFC loss at the hands of Nate Diaz via submission at UFC 196.

With McGregor having directed his patented trash talk at Nate and his older brother Nick leading up to the fight, former UFC welterweight champ Matt Serra has become the latest to fire back at the Irishman.

“Not being a c**k, but look at Conor. All the s**t you talked, take a nap, man,” Serra said on The Three Amigos podcast. “It’s not like your arm was about to break. I understand you want your career and if it was a kneebar, you’ll be out for six months, but dude, if worst comes to worst, you’ll think you’re in your bedroom. That’s it.”

“I consider the Diaz brothers friends,” he added. “They’re like extended family, them being under Cesar and me being under Renzo, we’ve always had mutual respect. They’re such respectful guys. People don’t know that about them, but they really are.”

Serra’s main problem with McGregor’s trash talk centered around the 145lb champ mocking Nate for teaching children’s Brazilian jiu-jitsu classes while also embodying the persona of a bad boy.

“Don’t get me wrong, I enjoy Conor McGregor, but the s**t where he went in on Nate about teaching the kids jiu-jitsu, now look, it’s one thing to be witty and this and that, but now you’re writing some s**t, trying to be clever,” Serra said. “You start crossing lines and your karma is not good, either. You start making fun of the guys teaching jiu-jitsu classes… he could be out in the hood doing dirty s**t, but he’s in there teaching kids martial arts, you dumb f**ker. How dare you! That’s f**king stupid. You want to make your money? Make your money, but that’s stupid.

“That annoyed me, and I love the Diaz brothers, so when he (Nate Diaz) f**king lit him up, when he started landing, I was going nuts.”

Matt Serra can currently be seen on UFC web series Dana White: Lookin’ for a Fight.
