Michael Bisping has opened up on an unlikely beef with former three-time UFC featherweight title challenger Chad Mendes.

This unexpected beef between Bisping and Mendes stems from a May Instagram post from Bisping’s former opponent Tim Kennedy. In his post, Kennedy looked back on beating Bisping, and ripped into the Englishman for his trash talk.

In the replies for this post, Mendes reportedly weighed in and shared his own gripes about Bisping.

Bisping did not appreciate the comments of the featherweight.

“I did see Chad Mendes the wee f—ing sh—e,” Bisping said on his podcast Believe You Me. “He f—ing went on Tim Kennedy’s page and called me ignorant, disrespectful and all this type of stuff.”

Bisping continued, sharing a segment of a message he sent to Chad Mendes at the time. He certainly didn’t hold back in his correspondence with the American.

“You little steroid cheating fuck. Don’t be sour because your career amounted to nothing. Ignorant and disrespectful? What, like disrespecting the sport by taking steroids by dishonoring yourself and your opponent in a sport that someone could die? Shame on you, you little dipshit.”

What do you think of this unexpected back-and-forth between Michael Bisping and Chad Mendes.
