Chechen UFC star clashes with Brazilian rival in gym bust-up (VIDEO)

Khamzat Chimaev is preparing to take on Nate Diaz at UFC 279

UFC sensation Khamzat Chimaev appears to have made an enemy in former middleweight title challenger Paulo Costa after a clash in the gym, and has also warned Nate Diaz and his camp about pulling any stunts at their press conference ahead of their showdown in Las Vegas this weekend.

Chechen-born Chimaev is preparing for the biggest fight of his life UFC 279 where he will take on the legendary Diaz in the headline bout he hopes will give him a shot at the welterweight title and its holder Leon Edwards should he prevail.

Simultaneously, the 11-0 contender has also campaigned at middleweight and wants to become champion there too. 

And in footage caught on camera, Chimaev could be on his way to meeting a big scalp in the division in former title contender Paulo Costa, who tried and failed to relieve current ruler Israel Adesanya of the crown in 2020, while appearing as if he has a settle to score with the Brazilian meme king.

With Costa appearing to have just finished a training session in the octagon with Diaz's teammate and former UFC welterweight title challenger Jake Shields, Costa makes his way over to Chimaev and his entourage on the other side of the cage at the UFC's Las Vegas Performance Institute.

"Did you say you want to f**k me up?" Chimaev asks, to which Costa replies calmly: "I want to fight you, do you want to fight me?"

This making Chimaev irate, he then has to be held back by his colleagues and says: "I want to f**k you up now, p***y boy. Brazilian p****y."

WARNING: STRONG LANGUAGE
