UFC bantamweight champion Ronda Rousey has her sights set on never losing inside the cage. And, through six bouts, she has done just that, earning six first round submission victories.

This Saturday night, Rousey will look to make it 7-for-7 against Liz Carmouche in the main event of UFC 157. It will mark the first time that female fighters have competed inside the Octagon, but not the last.

“Of course, I’m gonna beat Liz Carmouche. And everyone that comes after her,” Rousey said. “I’m going to retire undefeated and there’s not anything these girls can do about it. They can try. They’re welcome to try. But it’s not happening.”

The former Olympian has perfected the armbar, earning six wins via the submission. She has defeated the likes of Miesha Tate and Sarah Kaufman, but knows Carmouche will be a tough out – but still plans to exact her gameplan.

“She’s a legit fighter,” Rousey said. “But, if you break somebody’s arm, it’s broken. That’s not subjective. You can get the referee to stand her up, but she’s gotta fight the rest of the fight with one arm.
