Remember the female fighter who knocked out her opponent on the Octagon barely seconds after the game began? Apparently, her rumored next assignment is giving her the chills.

UFC bantamweight champion, Ronda Rousey, has this gut feeling that MMA fighter, Gina Carano, would test her inside the cage even if the latter hasn't fought in five years, according to her interview with ESPN. 

"Well, I want to win, of course," Rousey began. "But my coach said from the start that Gina is the worst style matchup for me. I'm not just saying that."

"The only thing I have to worry about is the one-punch knockout," she said, adding, "That's not something you lose because you made a couple of movies."

"She's the one who can knock you out while standing on her feet with one punch. That's what makes her the most dangerous," ESPN quoted from the woman who knocked out her opponent, Alexis Davis, in 16 seconds, in her fourth title defense.

A 10-0 record makes Rousey a dominant UFC figure with her back-to-back TKOs victories vs Sara McMann and Davis, the Bleacher Report said, while Carano's last match was a TKO from Cristiane Justino in August 2009.

Carano traded her career for a shot at show business, starring in action movies like "Haywire" and "Fast & Furious 6," but she has been rumored to ink a deal with the UFC for months now.

A report from Yahoo Sports noted Carano's "excellent" striking skills, with Muay Thai and mixed martial arts as her style bibles, but reported that many observers believe that the real threat to Rousey is Justino.

Randy Couture, who helped train Carano in the past, said her UFC debut against Rousey "doesn't make a lot of sense," MMA Fighting reported.

"My sincere hope is that they give her a chance to get up to speed, get back into top fight shape and really kind of shore up her grappling technique and that side of her game, and then it would be an amazing fight," Couture told Ariel Helwani on The MMA Hour.

But based on the ESPN interview, Rousey doesn't think Carano has lost her fighting skills.

"You're going to be surprised: It'll be one of greatest fights to ever happen in the history of women's MMA," she told ESPN.
