Many MMA fans are desperate to see Rousey do battle with Cyborg, the one fighter that pundits believe may be in with a shot of beating the former Olympian.
However, with Rousey fighting in the 135 pound division and Cyborg coming in at 145 pounds, even the Brazilian's impending move to UFC may not be enough to see the pair enter the ring.
Despite this, Rousey has not given up hope that the fight may one day happen.
"I mean, Pacquiao-Mayweather had about a five-year buildup," Rousey told MMA Hour. "We're about at three, so I'd say I would keep my hopes up til five, then after that, I'm moving on with my life."
