Dos Anjos, who has an 8-1 record ever since restarting his UFC career in 2012, has also made it clear that he intends to finish Pettis off before the fight is over.
"One thing I can be sure about — this fight is not going to go to the judges," Dos Anjos told Fox Sports. "I'm going to finish him."
In his 18 wins thus far, Pettis has stolen the spotlight on numerous occasions with his flashy head kicks and powerful rib shots. However, dos Anjos will have to keep his wits about him and ensure that he doesn't become a victim of Pettis' signature move, the 'Showtime' kick.
While Pettis will be looking to stun dos Anjos with his spectacular array of moves, the 30-year-old Brazilian is confident that he can stop Pettis in his tracks with brute strength and a series of hard hits.
"I'm so confident. I don't think I've ever been as confident as I am now," dos Anjos said. "I think he's a great champion with great stand-up and I don't do cage walk kicks, I don't do back flips, I don't do spinning back kicks, but I hit hard. That's what I'm going to do to him."
However, despite being on a mission to improve his own record and win his first UFC title, dos Anjos admitted to having nothing but respect for Pettis.
"He does things fighters aren't supposed to do," dos Anjos said. "He's good on the ground and he's not just a good stand-up fighter.
"I just can't wait until March 14 to get locked in the cage with him and we're going to see who is the lightweight champion."
