Manny Pacquiao pronounced himself ready to fight Floyd Mayweather, saying he's willing to engage the unbeaten American in the middle of the ring if that's what it takes to win. The eagerly-anticipated May 2 welterweight unification showdown in Las Vegas promises to be the most lucrative fight in boxing history.

"I am very excited," Pacquiao said Wednesday at the Wild Card gym in Hollywood. "My training and my conditioning is good. I can feel it. I am ready."

Pacquiao says that is why he is training harder and with more drive and determination than for any other fight in his career.

"I know this is one of the biggest fights ever in boxing," he said. "I am not saying it is the biggest, because that would be insulting to the other fights that have been done already. But it is one of the biggest."

On Tuesday, Mayweather's adviser - Leonard Ellerbe - said his fighter was coming in there to knock Pacquiao's head off.

"Floyd Mayweather is going to try to take Manny Pacquiao's head off," Ellerbe said. "You can count on that happening, too. Floyd Mayweather is looking to finish him off."

Pacquiao hopes Ellerbe's words are true. The Filipino star wants Mayweather to come to the ring with an aggressive mentality.

"If he [does] that, that's good for me [if comes looking for a knockout]," Pacquiao said. "I like that. We'll see. That's what I want, and that's definitely what the fans want - action."
