UFC female bantamweight champion Ronda Rousey seems confident about knocking down anyone in this planet, including undefeated American boxer Floyd Mayweather Jr.

In a Reddit Ask Me Anything session, "Rowdy" was again faced with the query if she is ready to face Mayweather.

She confidently answered that she can definitely do so, if they will battle it out in a "no-rules fight."

"Floyd is one of the best boxers of all time. He would definitely beat me in a boxing match. I unfortunately don't get into 'matches.' I fight for a living. In a no-rules fight, I believe I can beat anyone on this planet. Boxing is a sweet science with strict rules that I respect very much and aspire every day to improve at. But you said ruleless fight, and that's my honest answer," Rousey explained.

Yahoo Sports said the two sports personalities have been linked for a long time already, since the boxer denied knowing Rousey and with him even thinking that the UFC champ was a man.

The female MMA fighter also took a jab on Mayweather during the ESPY awards in July

"I wonder how Floyd feels being beat by a woman for once. I'd like to see him pretend to not know who I am now," he was quoted by People as saying.

In Rousey's hypothetical fight with Mayweather, UFC interim featherweight champion Conor McGregor seems to be in the UFC champ's corner.

"Ronda would dismantle him in seconds -- 100 percent. When you don't know how to grapple, you don't stand a chance," McGregor told The Guardian as he said that he can also do the same to Mayweather.

Aside from the possible matchup with Mayweather, Rousey also addressed questions about her facing Invicta champion Cris "Cyborg" Justino.

"The delay is all about money, not her weight. She made 145 pumped full of steroids. She can healthily make 135 without them. Her shows that she headlines lose thousands of dollars, and the majority of the tickets are given away because no one will buy them," the Los Angeles Times quoted her as saying.

Rousey added that Cyborg needs to fight her before they both retire from the sport.

Speaking about her plans after UFC, the MMA fighter said she is exploring her potential with professional wrestling.

"I loved being in Wrestlemania and will find a way to get back in the squared circle I just have no clue when. And any real wrestling fan would want to be surprised anyway," the fighter said.

Rousey entered the WWE ring during WrestleMania 31 with The Rock, an appearance which got fans excited about her future stint in the WWE.
