Manny Pacquiao has been training hard for his upcoming fight against Timothy Bradley and he plans to use one of his biggest strengths to win - his jab.

The boxer arrived in Los Angeles on Saturday after completing the first part of training camp with Freddie Roach in the Philippines and both spoke about the anticipated match.

"I told Manny the other day, 'Manny, you have the best jab in the world and it drives me crazy that you don't use it,'" his trainer Roach told Yahoo Sports. "He can knock guys out with his jab. It's fast, hard and quick and I've been telling him he needs to use it more. In sparring, I've been getting him to double, triple and even throw four at a time. It sets up his left hand well."

Pacquiao, who will fight Bradley at the MGM Grand in Las Vegas on April 12, also agrees that using his jab will be critical for the match.

"The focus this time is on aggressiveness," Pacquiao added. "I don't think he's going to try to go toe-to-toe with me, but I have to be more aggressive than I had been. I have been working on being aggressive."

The two boxers first fought in June 2012 and the winner was Bradley. Despite Pacquiao's plan to incorporate his jab this time around, Bradley believes he lacks one important quality needed to defeat him.

"He's a nice dude, man," Bradley told The New York Daily News at a press conference in February. "Pacquiao is very humble, very spiritual. But I don't think he has that killer instinct. I don't think he has that fire in him. I really don't."
