On April 12 Manny Pacquiao will try to prove without question that he is back in full force and ready to return to the top of boxing by defeating undefeated Timothy Bradley, who earned a controversial split decision over him in June 2012.

Manny Pacquiao to "punish" disrespectful Bradley?

The loss to Bradley began Pacquiao's descent from the sport's pound-for-pound throne, which he once shared with Floyd Mayweather Jr. Now Floyd is the unquestioned top dog, with Pacquiao trying to reverse the damage the losses to Bradley and Juan Manuel Marquez did to his standing.

Since Bradley's suspicious victory, "Desert Storm" has improved, earning impressive wins over Ruslan Provodnikov and Marquez to slot himself third among most pound-for-pound rankings. Leading up to this fight, he questioned whether Pacquiao still had the hunger to conquer elite fighters anymore.

Marquez/Alvarado winner next for Pacquiao or Bradley?

"He's a nice dude, man," Bradley said. "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."

Pacquiao couldn't disagree more. "Because I am facing Tim Bradley again I am extra motivated for this fight. I may not have won the decision the first time we fought but I know I did not lose that fight. I want the world title he won from me back around my waist. I want to prove I am the better fighter."

To ensure that's the way this fight goes, Pacquiao said he's going through one of the toughest training camps of his illustrious career. "Freddie Roach and Justin Fortune are asking more from me in this training camp than I have ever given before and as hard as that is to do, I am giving them everything they have asked of me. Too much is at stake for me and for my country. I want to end my career on a winning streak and against the best fighters."
