Manny Pacquiao is eager to end his rivalry with Juan Manuel Marquez in resounding fashion as the duo prepare for their third fight next month.

The 2004 bout at the MGM Grand in Las Vegas was controversially scored a draw and four years later Pacquiao edged a split decision at the Mandalay Bay Resort and Casino - but Marquez has always insisted he should have been awarded both.

Pacquiao (53-3-2, 38 KOs) admits the Mexican's claims have served as the motivation to beat him again - but he doesn't want there to be any doubts on this occasion.

Speaking at trainer Freddie Roach's gym in Hollywood ahead of the MGM Grand clash on November 12, the pound-for-pound king told Associated Press: "I'm not upset, but I get excited because he's claiming that he won the fights.

"That's why I train hard, because I want to end this, all the doubts. This is our last fight.

"It seems personal to him because he talks too much, and he needs to prove it. He talks a lot, and it's not good for a fighter to talk a lot without action. Me, I don't talk a lot. I just do some action."

Roach believes the eight-division champion is preparing more aggressively than usual and expects him to wrap up victory against Marquez (53-5-1, 39 KOs) in the first half of the fight.

He said: "I don't think this fight is going to go six rounds. With Manny's footwork, he's just a completely different animal to the guy that fought Marquez the first time. (Marquez) has gotten up against Manny before, but I don't think he's going to be able to get up from the power Manny has now.

"He's a much stronger guy than he was at those smaller weight classes. He's just a completely different animal. We can put it to bed, finally shut them up, and be happy."

Pacquiao's strength trainer Alex Ariza said: "I don't think I've seen him more focused, and I think it's because it's personal, for sure.

"When something is personal, it's a lot different. He knows that he has to make a statement in this one. With everyone having questions about the first two, he has to make sure in this one that there's no doubt.

"We're going through sparring partners like you change underwear. I'm surprised that these guys are still coming back.

"I don't see Manny even touching gloves (with Marquez). He has a disdain for the guy, and I've never known him to dislike anyone.

"Manny is still a nice guy and everything, but there's something very Third World about him when he wants to be. He can be merciless. I've seen it, and it's been a long time since I've seen that. Usually he lets guys off the hook. He isn't letting anybody off the hook."
