Dana White says Ronda Rousey wants to be part of what could be the biggest MMA fight ever

Ronda Rousey hasn't agreed to return to the Octagon yet, but this superfight is waiting for her

A fight between Ronda Rousey and Cris "Cyborg" Justino would likely be the biggest UFC pay-per-view event ever. And UFC president Dana White says the former bantamweight champion is charged up about the possibility.

"I can tell you this, Ronda wants to fight Cyborg. Absolutely, positively wants to fight Cyborg, so we'll see what happens," White told TMZ. She's getting nasty again, and her head's in the right place."

White called a matchup between the two a dream fight, but added that Rousey regaining her bantamweight title would probably come first. A meeting between Rousey and Cyborg, 31, could possibly be the most highly-anticipated in the sport. But agreeing on a catchweight has always stood in the way. Last year, Rousey stipulated that she would only be wiling to fight Cyborg at 135 pounds, requiring her to lose 10 pounds of her normal fighting weight of 145.

After beating Lina Lansberg Saturday, Cyborg told MMA website Sherdog that she would be willing to fight anyone interested in taking her on, but only at 140 pounds.

"If they want me to fight at 140 I can, but they have to be top 10 [opponents]. I never picked opponents. I always let them pick the opponents for me. Anyone in the top 10 at 135 that wants to fight at 140 [I'll fight]. I'll do my sacrifice, I'll cry to make 140... And we'll make a great fight for the fans. I think that's what makes MMA grow."
