Daniel Cormier names the fighter who will replace Khabib as the UFC's best

Cormier - who had a former wrestler during his Olympic career - experienced some of the best wrestlers in the world from Dagestan, including Abdulrashid Sadulaev - a two-time Olympic winner and four-time world champion.

"They just know how to wrestle. I knew the moment I saw Khabib and then I saw Islam, I was like uh-oh, the Dagestanis are starting to do mixed martial arts, it's a problem for the world. That's absolutely what has happened."

"He's the best fighter in the world at that weight class. His abilities are just second to none."

"Let me tell you something, this Islam Makhachev is crazy," Cormier added.
