Braulio Estima: "I'm not gonna go there playing easy. I'm going to play my best game, and I will try to be the first guy to submit (Nick Diaz)."

"This is a once in a lifetime thing. Getting one of the top ones in MMA, and getting one of the top ones in BJJ, fighting together, for all the world to come and see. It's going to be amazing."

The 15-minute video is executed very well, so if you're even slightly interested in the match, I do suggest watching it. You can read the rest of the key quotes after the jump.

A lot of people consider him as the underdog... But he's a very tough guy. Very flexible. He has a phenomenal gas (tank). He's a triathlon guy so you know stamina is not his problem.

I'm coming back from a big break, which makes this thing even. I will be cutting a lot of weight... Which is a challenge that I want to give a go anyway, because I'll be fighting MMA in the lower weight, which is the same weight as Nick Diaz. So I want to start to feel how to fight at that lower weight class.

I am the favorite, and everyone expects me to go there and annihilate him. Which, if it happens, then good. But I am not going to underestimate him. I think he's a great fighter, and this brings a lot more pressure.

The guy is a special guy. It's going to be a tough match. I'm not expecting nothing easy. I'm not gonna go there playing easy. I'm going to play my best game, and I will try to be the first guy to submit him.

He doesn't care about points. He cares about submissions. And I'm going to go there too. I'm going there to beat him by submission.

This is a once in a lifetime thing. Getting one of the top ones in MMA, and getting one of the top ones in BJJ, fighting together, for all the world to come and see. It's going to be amazing.
