UFC icon Conor McGregor has branded Beneil Dariush as the "biggest nobody" in the business after he criticised the Irishman's potential fight with Charles Oliveira.
McGregor is due to make his long-awaited comeback from a broken leg, which he sustained in his loss last year to Dustin Poirier.
And it looks like he could be set to take on former lightweight champion Oliveira, who has repeatedly called him out for a future fight.
But news of that fight hasn't pleased UFC No6 ranked lightweight Dariush, who claims he was supposed to fight Brazilian Oliveira in 2020.
The Iranian-born American told The Fighter vs. The Writer podcast: "He’s talking about wanting to fight Conor McGregor, and he talks about how these guys never gave him a shot when he was outside the top five, blah, blah, blah.
"We were supposed to fight October of 2020.

"I have a fight contract, I can post a picture of it. I was supposed to fight Charles, and he pulled out of the fight, and then a couple months later, instead of fighting me, he fought Tony Ferguson.
"He said something about family issues and I’m not going to say, ‘Oh, he didn’t fight me, I can’t believe it.’
"Family comes first, I understand that. But the same thing people did to him, he’s doing to me.”
Dariush then went on to describe former double-champ McGregor as a "unicorn" which Oliveira is chasing.

He continued: "I understand the media has their thing, the UFC has their part, but for him to be chasing a unicorn, it’s super frustrating.
"There’s two clear contenders in front of you, and you’re trying to chase a unicorn. No one knows when Conor is going to fight again.
"The guy might not even fight this year. Make it make sense. It just doesn’t make sense.”
Dariush's comments provoked a response from former double-champion McGregor on Twitter.
McGregor responded: "Beneil Dariush is the biggest nobody in the company.”
