Joe Warren unified the Bellator bantamweight championship with a unanimous decision victory over Eduardo Dantas in the main event of Bellator 128 on Oct. 10, and another Brazilian could be next for "The Baddest Man on The Planet."

Patricio Freire, the current Bellator featherweight champion, suffered his first professional loss to Warren at Bellator 23 in 2010, and he wants to "clean" his record. After avenging the other loss of his record against Pat Curran, "Pitbull" is willing to drop to 135 pounds to face Warren.

"I sent Scott Coker and Rich Chou an e-mail, but they haven’t answered me yet. I sent Warren a few messages on Twitter, and he hasn’t spoke. I want this fight," Freire told MMAFighting.com.

"Joe Warren was my first loss, and it was a controversial one. I beat him a lot, knocked him down and slept (him) for a second, but the referee didn’t stop the fight and he won via split decision. I don’t think I lost that fight, many people think I won that fight.

"He won the title right after and ended up moving down to 135 after a few losses. He’s a world champion now, and our history hasn’t changed. I’m sure I will knock him out in the first round."

Avenging a loss is Freire’s main goal in this fight, but he also wants to become the first man to hold two Bellator titles at the same time.

"The main reason is avenging that loss and cleaning my record, but both things motivate me. Having the chance to make history like Dan Henderson, and winning two titles at the same time in a big organization, would be huge for my career," he said. "It’s time. I’m the featherweight champion and people still doubt me, so I want bigger challenges."

"Pitbull" never had any trouble making 145 pounds during his MMA career, and he’s confident that cutting an extra 10 pounds wouldn’t be an issue.

"I made 145 pounds for my last fight without entering a sauna," he said. "My natural weight is 158 pounds now, and I can make 135 pounds easily with a good diet. I’ll be strong on fight night."

Freire vs. Warren could be the first fight between current Bellator champions in the history of the promotion.

"If Bellator doesn’t book this fight, it’s because they don’t want a Brazilian to hold two titles at the same time," Freire said. "But (this fight) would be great for Bellator, and it would be even better for me. I want to beat this guy up, he talked too much crap. He’s actually a nice guy backstage, treats me well, but a fight is a fight."
