Hall of Fame trainer Nacho Beristain believes Manny Pacquiao will emerge victorious again in his upcoming rematch with Timothy Bradley on April 9 at the MGM Grand in Las Vegas, Nevada.

Beristain, who is famous for training Mexican boxing warrior Juan Manuel Marquez, is familiar with both Pacquiao and Bradley. He trained Marquez in his four fights with Pacquiao, where the Mexican won by knockout in their fourth bout. Marquez also faced Bradley in 2013, where the former lost via split decision.

Beristain said that Pacquiao is simply the better fighter. He also believes the Filipino boxing champion opted to pick Bradley because he knows he was to win in his farewell fight.

"In addition to being a good fighter, Pacquiao is a responsible fighter, professional," Beristain told ESPN Deportes, via BoxingScene. "He is not going to walk away with a loss, so he chose Bradley. And Bradley is a good fighter but we all know who will win unless Bradley becomes a very different fighter than what he' has shown throughout his career."

Bradley, who is the reigning World Boxing Organization welterweight champion, is coming off a ninth-round knockout win against Brandon Rios, which was his first fight under new trainer Teddy Atlas.

When asked if the change of trainer -- from Joel Diaz to Atlas -- will make a difference in the third fight between Bradley and Pacquiao, Beristain is convinced that the reigning champion and his new trainer does not have enough time to make changes.

Like Beristain, Kenny Porter, father and trainer of former welterweight champion Shawn Porter, is also convinced that Pacquiao will win against Bradley. While Pacquiao has not fought since losing to Floyd Mayweather in May last year, Porter is convinced that the former eight-division champion still has what it takes to score a convincing victory.

"Tim is a great fighter and I am a huge Tim Bradley fan, but I think Manny Pacquiao still has what it takes to win this fight," Porter told On The Ropes Boxing Radio. "But if he doesn't have everything that it takes like he once did and if he slips up at all, Tim will take it."

Porter is convinced, though, that Atlas could make a difference in the upcoming fight, especially if Bradley will have full confidence in executing their fight plan in April.

"The thing that most people don't realize and understand, they're looking for the trainer to make a difference because of the way he trains or because of his personality, but the fighter is looking for the trainer to make a difference because he believes in that trainer," Porter said.
