UFC lightweight Arman Tsarukyan commented on Umar Nurmagomedov's defeat in his fight with Merab Dvalishvili.
"Umar gave a good performance but he didn't have difficult opponents like Merab. Umar had a great first two rounds, but then he got tired. Yes, he talks about the hand, but it was obvious that he was tired. Of course, he lost because he was tired - that's obvious. With a broken arm, you can kick and defend yourself, and fatigue is something completely different that is immediately visible and can't be confused with anything else. Merab has the best cardio in the UFC. He has crazy stamina - he never stops. You can't train that - it's genetics. Georgian genetics and mountains.
