Manny Pacquiao has been hearing a lot of taunts from Timothy Bradley, but the former pound-for-pound king refuses to engage in war of words, saying that he will just let his fist do the talking.

Pacquiao said that Bradley's continuous taunting is doing no good for the undefeated champion with the eight-division champion saying that it is just making him more motivated to win in their upcoming rematch on April 12 at the MGM Grand in Las Vegas.

"The more he says that, the more he inspires me to show the hunger and killer instinct he's talking about," Pacquiao said. "It's good for me but not for him I think."

Pacquiao is aiming to prove that he is better than Bradley, who ran away with a controversial split decision victory in their WBO welterweight title showdown in June 2012.

The 35-year-old Filipino boxing icon reiterated that he has already moved on from that controversial match, saying that he was not bothered by the decision after that fight because most people are convinced that he clearly won against Bradley.

"I'm not angry after the decision. I understand that with the officials, nobody's perfect in this world. I have to understand that it's part of boxing. I wasn't bothered after that fight," Pacquiao told RingTV. "I went home and the reaction of the people was not negative, it was positive, so, they understood that I won the fight."

Trainer Freddie Roach echoed Pacquiao's statement, saying that there's nothing to get mad over from the previous fight, but he pointed out that Pacquiao will look to become more disciplined in their upcoming showdown to score a knockout win against the 30-year-old Bradley.

"It's part of life, winning and losing, and revenge is great, and that's what we have a chance to do here," Roach said. "We have a shot at reversing that bad decision and to get the win this time, and hopefully, if everything goes well and we fight the right fight, then we'll knock this guy out."

Pacquiao bounced back from his loss to Bradley and Juan Manuel Marquez with a dominating victory over Brandon Rios in his comeback fight in November last year.
