The world's most dangerous woman challenges Mayweather

Her record is devastating. The american Ronda Rousey was recognized this year as the most dominant athlete on the planet.

For many people she is considered "the most dangerous woman in the world" and she believes that is able to win a fight "without rules" anyone on this planet, including Floyd Mayweather, the best boxer kilo for kilo today.

Rousey has reason to believe what she says. At age 28, the American fighter is the undisputed champion bantamweight Ultimate Fighting Championship (UFC), the main promoter of mixed martial arts.

In the prestigious ESPY, Rousey won the categories of Best Female Athlete and Best Female Fighter.

She has won all 12 fights and 11 are knocked out his opponent in the first assault. In her most recent bout, the Brazilian Bethe Correia lasted only 34 seconds.

 Without rules

Before that fight Rousey pointed to a rival's poster, Mayweather, whom she challenged in delivering the ESPY awards.

"I wonder how you'll feel if Floyd once he is hit by a woman," Rousey said, referring to the conviction that the boxer had to meet three months for domestic violence.

Floyd Mayweather does not consider Rousey rival and set the date for his last fight in the ring, on 12 September.The highest paid athlete in the world was quick to respond to the challenge of not knowing who said who she was and that he had to clarify that it was a woman.
