Nurmagomedov called Sandhagen his most difficult opponent

Umar Nurmagomedov, UFC lightweight division fighter, named the most difficult, in his opinion, opponent in his weight class.

"I have to fight Corey. Last year our fight was canceled because of my injury and now I have to finish this thing. Everyone says I'm afraid of him. I want to prove that's not true. I think Corey is the toughest opponent for me in the lightweight division. Sandhagen is very talented, technical, it's a big challenge for me. If I'm going to pick an opponent, it's going to be Corey. I think Sandhagen is a tougher opponent than O'Malley. He has a high fighting intelligence," Umar said in an interview with ESPN MMA.

Recall, earlier Nurmagomedov challenged Sandhagen, and the latter accepted it.
