After battling it out with some of the greatest and strongest fighters in the UFC, Ronda Rousey has pretty much faced every tough opponent in the league.

But she has yet to slug it out with Invicta champion Cris "Cyborg" Justino, who recently signified her intent to seek legal remedy for Rousey's steroids comments.

Yahoo Sports said a fight between the two has been rumored since 2012. After Rousey beat Bethe Correia last Saturday in just 32 seconds, Justino is now being challenged to go against the undefeated UFC champ.

"There are a few caveats to the deal, however. First, Justino must make Rousey's bantamweight divisional limit of 135 pounds - something she has yet to manage. And, of course, there is still the issue of signing Justino to an official UFC contract," explained Yahoo Sports.

Justino is currently signed to Invivta FC, UFC's all-female sister promotion.

But the Invicta champion wants to take their battle first to the court before into the Octagon.

After her recent victory, ESPN said that Rousey expressed that she is ready to take on any battle.

"I'm prepared to deal with anything, that's why I'm the champion. I fight in the UFC, in the 135-pound division. She can fight at 145 pumped full of steroids or she can make the weight just like everybody else without them," Rousey said in the ESPN report.

The UFC bantamweight champion touched on Justino's positive steroid test last December 2011 which the Invicta champion blamed on her dietary supplement.

On her Twitter account, Cyborg said that she has passed drug exams and came out clean in the previous years. She is challenging Rousey to take this matter to the courts.

"I pass the same exams @rondarousey takes to prove she's clean for the same company #zuffa. #drugfree @ufc. @rondarousey you can not slander me with lies in the media. My lawyer will call @Primetime360ESM," Cyborg tweeted.

The public is certainly hoping that all the trash talking and threats of legal remedies will be set aside to give way to one of the biggest MMA fights in history.

UFC president Dana White mentioned in a Bloody Elbow report that the potential fight could generate an estimated of 2.5 million buys.

"I think that fight is massive," White said.

White admitted that getting Cyborg could be a bit "complicated."

"Cyborg has to make the weight. If you see tonight, if you look around, and you see that Ronda is here in Brazil, with a sold-out crowd, the place was cheering for her, which I've never seen in Brazil, ever, Brazil only cheers Brazilians, and they're cheering for Ronda, I'd be cutting weight now and chomping at the bit to fight Ronda if I was Cyborg," he said.

"That fight is ready to roll whenever Cyborg is ready," White added as if encouraging the Invicta champ to do whatever it takes to meet the weight requirement.
