The scariest soap opera in sports ain't over just yet ... 'cause Cris Cyborg says a superfight between her and Ronda Rousey might still go down one day.
We got Cyborg training in L.A. for her fight with Holly Holm ... and the women's featherweight champ told TMZ Sports "maybe this fight can happen" if everything were to fall into place.
The problem -- Cris doubts Rousey's ever gonna step foot back inside the UFC Octagon.
Still ... it's a 180 from the stance Cyborg took a couple months ago, when she said she didn't wanna scrap with Ronda anymore because she's a loser.
Cris also told us not to rule out a champ vs. champ matchup with Amanda Nunes ... though she'd really prefer not to smash a fellow Brazilian.
