MANILA, Philippines - Boxing's pound-for-pound king, Manny Pacquiao, is confident that he has improved into a complete fighter, and that improvement will be the difference when he faces rival Juan Manuel Marquez for the third time on November 12.

"Which of us has improved more? I have improved a lot. I am a more complete fighter than when we fought previously. I am now a two-fisted fighter," Pacquiao said in an interview with Gareth A. Davies of The Telegraph.

In their first two meetings, the southpaw Pacquiao primarily used his powerful left hand to knock down Marquez a total of four times over the course of 24 rounds.

But Marquez got up each time, salvaging a draw in their first meeting and settling for a close split decision loss in the second.

Pacquiao insisted, however, that he no longer just relies on his left hand.

"My right hand is as potent, as powerful and as dangerous as my left. I have as much confidence in my right as I do in my left," he said.

Pacquiao showed the power of his right hand in his May 2009 fight against Britain's Ricky Hatton, having dropped the Englishman with a right hook in the first round.

His trainer, Freddie Roach, agreed that Pacquiao is no longer just a left-handed puncher.

"Marquez will be surprised when he faces this version of Manny. He no longer fights in one direction or with one hand," Roach said. "Manny has become a complete fighter."

Roach added, Pacquiao has learned to move in both directions and can throw "potent punches" with both hands.

"Manny has so many more weapons than the last time they fought," he said.

Going for the knockout

Roach admitted that his prized ward may have gotten "complacent" in the first two fights against Marquez, leading to the controversial results.

"The last two times they fought, Manny got complacent after knocking Marquez down," he said. "Instead of fighting his own fight, he followed Marquez and began fighting his fight - big mistake."

Roach remains confident, however, that Pacquiao was the winner in both of the battles, although the results were closer than they should have been.

"I'm worried that Marquez could have Manny's number. He is the only fighter who seems to have figured out Manny's style," he admitted.

The five-time Trainer of the Year has repeatedly said that Pacquiao will be going for a decisive knockout victory this time around.

"Manny is going to shut up Marquez once and for all - I'm sick of his whining," Roach said, adding that the fight will be over by the sixth round.
