Brandon Moreno: Deiveson Figueiredo rivalry 'by far the biggest' in UFC flyweight history

Brandon Moreno firmly believes he continues to make history. The UFC interim flyweight champion, and former undisputed titleholder, already put his name in the history books by becoming the first Mexico-born champion in UFC history. Well, on Saturday night Moreno (20-6-2 MMA, 8-3-2 UFC) is set to make history once again, as he takes on champion Deiveson Figueiredo (21-2-1 MMA, 10-2-1 UFC) in a title unification bout part of the co-main event of UFC 283 in Rio de Janeiro, Brazil.

This is the fourth time Moreno and Figueiredo will meet in the octagon, making it the first quadriology in UFC history. But it doesn't stop there. Moreno strongly feels his series against Figueiredo stands today as the biggest rivalry in flyweight history.

"As far as rivalry, yeah (this is the biggest) by a lot," Moreno told MMA Junkie in Spanish. "What other one could get close? Demetrious vs. Henry (Cejudo)? Demetrious vs. (Joseph) Benavidez? think speaking of history, rivalry, the bad blood, I think Deiveson and I, we have by far the biggest rivalry of the division."

And beyond rivalry and feuds, "The Assassin Baby" also believes his fourth encounter holds plenty of significance in the weight class. Moreno knows there have been other pivotal moments in the division, so he won't say this unification bout is No. 1, but it's certainly among the most important fights in flyweight history.

"So I don't know. I think maybe my ego is talking, but I think what we're doing right now Deiveson and I, it's really big, it's huge. And it's opening the door for other contenders to keep developing.... think what Deiveson and I are doing is the best thing that could happen to the flyweight division."
