Manny Pacquaio's trainer believes that the Filipino boxer will beat Tim Bradley at their rematch on April 12 at the MGM Grand in Las Vegas.

The 35-year-old has been in the Philippines training with Freddie Roach, who said that Pacquaio's work ethic will help him take the victory.

"We can talk and bullsh-t, but at the end of the day it's about who's the best conditioned fighter the night of the fight," Roach told Hustleboss. "Bradley is a workhorse; I know he trains hard. But you know what? My guy works hard also."

Roach added, "We'll be in better shape than him and that's why we'll win the fight."

The two first fought in June 2012 and the winner was Bradley, who believes Pacquiao 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."

Expert Larry Merchant also doesn't think Pacquiao stands a chance.

In an interview with the boxing website, RingTV.com, Merchant said that Pacquiao, who hasn't won a fight by stoppage since defeating Miguel Cotto in 2009, seems "eager" for the fight, but he doesn't believe he can beat Bradley.

"The question for Manny is whether he will have the ability and the fire to force a fight, and to return a little bit to his previous incarnations," Merchant said.

Merchant, a former sportswriter and longtime commentator for HBO Sports added, "Bradley wins every place that he goes. If there is any resistance, he wears you out. He's a damn good fighter."
