Brazilian lightweight prospect Charles Oliveira (14-1 MMA, 2-1 UFC) may be just 21 years old, but he knows exactly what he wants out of life.

And as it turns out, he’s got just two years to get it done.

“I really want to be the youngest UFC champ ever,” Oliveira told MMAjunkie.com (www.mmajunkie.com). “With my last fight and Mr. Jon Jones winning the belt, that does not leave me much time, but I will fight every month if I can to achieve this goal.”

As 2010 wound to a close, Oliveira looked primed to do just that. The phenom burst onto the scene with a 41-second submission win over Darren Elkins at UFC on Versus 2 and followed that up with a third-round tapout win over “The Ultimate Fighter 8” winner Efrain Escudero at UFC Fight Night 22.

The results earned Oliveira a pair of “Submission of the Night” bonuses.

“I like to keep my bonus check money in the bank,” Oliveira said. “I did buy a computer, but life is the same. I just train jiu-jitsu, then spend time with my family and my girlfriend.”

But while his life outside of the cage remained the same, his life in it was progressing rapidly. Many MMA pundits were declaring him the “next big thing,” and his next bout agreement reflected the growing respect, as he was slotted against top-ranked lightweight Jim Miller.

Some thought the UFC 124 contest would prove Oliveira’s coming-out party. Instead, he was submitted in just under two minutes, and Miller took home his own “Submission of the Night” check. Despite the setback, Oliveira said he has no regrets at taking the big jump in competition.

“The fight felt right – big show, big name opponent, in Canada with Georges St-Pierre fighting,” Oliveira said. “How could I not take that fight?

“I just got caught in a leg lock. No one can stay undefeated. Jim Miller is very good, but maybe next time I can catch him.”

While the victory for Miller proved just one more win in his long line of victories, the defeat for Oliveira was his first in 15 professional fights. It’s a feeling he admits he didn’t much care for, and it’s been fueling his drive ever since.

“Believe me, the loss has made me stronger then ever,” Oliveira said. “I have tasted defeat, and I never want to feel like that again. I have been training harder then I have ever trained before. The motivation it gave me was 100 times more then any victory can ever give you.

“The feeling of losing is something I do not like. It was very frustrating. I wanted to fight again right away. I wish we could have done the best out three that night with Jim Miller.”

Oliveira gets his chance for redemption at this month’s “UFC on Versus 4: Marquardt vs. Story” event, where he takes on Nik Lentz (21-3-2 MMA, 5-0-1 UFC) on June 26 at Pittsburgh’s Consol Energy Center.

Lentz brings an incredible 14-fight unbeaten streak into the cage, but his six octagon outings have been largely panned by fans who deem his style as less-than-exciting.

“I promise everyone that Mr. Lentz will not be able to use his ‘boring’ technique on me,” Oliveira said. “I am coming to fight and finish. I have only one decision on my record, and to me, that is almost like a loss. I want to be an exciting fighter. I want to get submission or knockout of the night every time I fight. I have had three already – two good ones, one bad one – and I want to keep this streak going.

“I am going to push the pace on Mr. Lentz, and I will always be looking for finish, whether it’s by submission, knockout or slam. I will be doing a lot of high-risk moves for high rewards. I will help Mr. Lentz have a great chance to get his first fight of the night; I will turn Mr. Lentz into exciting fighter.”

It’s a big boast from a young fighter, but Oliveira has already shown the flashes of brilliance necessary up back up such a claim. An impressive win would certainly earn Oliveira back much of the momentum he lost against Miller.

And while “do Bronx” isn’t looking past Lentz, he’s always got his eyes on the ultimate prize.

“I’ve been working very hard with my coaches Erick Cardozo, and ‘Macaco’ (Jorge Patino) to correct my mistakes,” Oliveira said. “My manager, Wade Hampel, still believes in me, and my sponsors Dethrone, Hayabusa, Blowout Cards, Best Bet Marine Services, Pete MacCallum, Bony Acai, Morph Jeans and Pretorian Hard Sports have all stood by me.

“I’m all business. I will fight whoever the UFC tells me to. I just fight. That said, I look forward to beating Mr. Lentz, and I could see Mr. Miller and I fighting for the belt very soon.”
