There's a lot of heat between Khabib Nurmagomedov & Diaz's crew and it all stems from a huge brawl at an MMA event.
Nurmagomedov got into a fight with Nick and Nate Diaz at a World Series of Fighting (WSOF) event in Las Vegas back in August 2015.
Chaos ensued when Nick launched a drink at Khabib's face.
Crazy scenes. Another angle of the brawl surfaced online after Nate jumped to the defence of Conor McGregor.
Nate replied to a Tweet, recalling the infamous incident. "I slapped you in your head you and your team didn't do shit ... Live with that ur all pussies," he wrote.
The UFC lightweight king fired back and Tweeted a video of their teams clashing.
"You was hiding behind security and ran away coward, it's clear on the video. We just smashed your team that night you punk."
Diaz jabbed back: "Be real You know what happened live with it."
Nurmagomedov then shared another video.
Bloody hell, lads, just fight already - you know, officially. In fact, UFC have attempted to match them up, but according to Dana White, Nate rejected the bout.
Nurmagomedov has since become UFC champion and defended his title in stunning fashion by beating McGregor at UFC 229.
Nate, and Nick for that matter, remain uninterested in returning to the cage, unfortunately.
Will we ever get Nurmagomedov vs. Diaz...?!
