Ultimate Fighting Championship (UFC) women's bantamweight champion Amanda Nunes is confident of beating Mixed Martial Arts (MMA) superstar Ronda Rousey at UFC 207, claiming that she is keen to prove to the world that she is the best champion the UFC ever had.

The Brazilian who beat Miesha Tate to win the title at UFC 200 via a rear naked choke submission in the first round has a 13-4 win-loss MMA record and comes into this clash full of confidence registering four consecutive victories.

"I don't have the same visibility yet. People still think Ronda Rousey is the best, the most dominating fighter in the division. That's why I want to fight her. I want to prove everybody wrong. I'm going to be the best champion UFC has ever had", Nunes said, as quoted by Los Angeles Times.

The 28-year-old who cruised past Tate at UFC 200 believes that fight was just the start and she can do better. The Brazilian is confident that she can do better at UFC 207 and is training with Rousey in mind especially in her ground game and judo blocking.

"The way I fought that night (UFC 200), the whole camp went exactly like that. Now in every fight, I want to bring the best out of me, and my next fight will be better than UFC 200. I'm going to be more powerful, faster, amazing with my ground game and great in my judo blocking. I'm going to be the best and sharpest that people have ever seen."

Nunes, who is the first openly gay champion in MMA history, has hit out at the American's fame, revealing that being the best in the world is her only concern.

"This is a dream come true for me, and it's not about anything else other than me following my dream. I don't want to be famous, I don't want any of those things Ronda has. I want to be champion, the best in the world. I'm that now, I have that reward and now I'm moving forward to help people", the bantamweight champion added.

The Rousey vs Nunes clash is scheduled to take place on 30 December at the T-Mobile Arena in Las Vegas, Nevada.
