UFC analyst and commentator Joe Rogan has called Kyrgyzstan fighter Valentina Shevchenko a 'f*****g monster' in the flyweight division.

The 31-year-old, who stopped Katlyn Chookagian in three rounds at UFC 247 on February 8, has now won five fights in a row since being defeated at bantamweight by Amanda Nunes in September 2017.

And Rogan believes that since her move down to 125 pounds, she may prove unbeatable.

Speaking on his podcast The Joe Rogan Experience, he said: “Valentina at 125 is a f*cking monster. She is so good. It doesn’t even make sense. That fight, I did my best to pump up Katlyn Chookagian and to make it sound like it was going to be a good fight. But, all I was thinking of is ‘How is this girl going to beat her?'. She does everything perfect.”

“Valentina makes you pay. So like, all those shots that she (Katlyn) would throw for volume, (this) is different. You put the shots out there and then (Valentina’s punches) come back at you. 

"The kicks come back at you and you’re like ‘F**k.’ Now everything is at a distance. And you lose your ability to engage. You get nervous because every time you engage, she’s looking to take your f*cking head off!"

Shevchenko's next fight is yet to be announced.
