During an event in Russia over the weekend, UFC lightweight champion Khabib Nurmagomedov challenged Floyd Mayweather while standing next to Mayweather Promotions CEO Leonard Ellerbe.

Khabib told Mayweather, "Let's go, Floyd, we have to fight now. 50-0 vs. 27-0, two guys who never lose. Let's go, why not? Because in the jungle, there's only one king. Of course I'm the king because he cannot drop McGregor, but I drop him easily. Let's go."
