Charles Oliveira has become a dominant force at lightweight and the former UFC champion has many fighters wanting to prove he can be beaten. The last man to beat him, Paul Felder, recently gave his take on the toughest fight for the Brazilian.

The options at this point have come down to Beneil Dariush and Islam Makhachev. Both men are expected to fight for the UFC lightweight title next depending on who gets picked.

“I am retired, so it can’t be me, but dare I say someone like Beneil Dariush is more of a threat to [Oliveira’s] particular style,” Felder told MMA Fighting. “Because — and vice versa, I said the same thing when Khabib [Nurmagomedov] was still around — I always said that I thought Charles would be one of the bigger threats to him because of his style and the way he grapples and accepts bottom position, but is so dangerous from there.”

Paul Felder likes Beneil Dariush because of his well-rounded game compared to Islam Makhachev. The UFC lightweight expects the matchup to be a very interesting one between the two.

“I think a guy like Charles, you’ve got to get somebody [like Dariush],” Felder said. “The way he ran through Tony [Ferguson] was impressive. I think Beneil [is a threat to Oliveira], even more so than Makhachev, just because [Makhachev] going to try and wrestle him, and Charles he has a way around those kinds of exchanges.

“It doesn’t matter if you have great takedown defense against Charles Oliveira,” he continued. “He will find a way to your back. I’m going to throw a big Hail Mary out there and say my pick [to beat Oliveira] is Beneil Dariush.”
