While Floyd Mayweather is arguably the greatest boxer of all time, UFC phenom Ronda Rousey believes she would come out victorious in a battle against the undefeated champ if the rules found in boxing were absent from their fight.

Rousey, who recently beat out Money for the Best Fighter ESPY and has been lightly beefing with Mayweather, told fans during a Reddit AMA on Monday that "In a no-rules fight, I believe I can beat anyone on this planet."

"Do I think I would legit beat Mayweather in a ruleless fight? Floyd is one of the best boxers of all time," Rousey told a fan who asked if she could beat Mayweather if there were no rules.  

"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."

What do you think, would Rousey take down Mayweather in an MMA-style battle?
