Juan Manuel Marquez, the world lightweight champion of the World Boxing Association and World Boxing Organization, is training very hard at Mexico's Iztacalco Gym. Marquez took part in his second day of tough sparring, as he prepares for his trilogy fight with WBO welterweight champion Manny Pacquiao on November 12 at the MGM Grand in Las Vegas. The fight takes place at a catch-weight of 144-pounds.

"I'm getting the best preparation of my career for the fight on November 12, and gooing there with one goal in mind - to knock out Manny Pacquiao," Marquez said.

Marquez met with a team of specialists, and devised a training plan like never before. He wants to give himself the necessary speed and power to achieve his goal of a knockout victory. Juan Manuel sparred for two rounds with Ramses Agathon, and two more with José Emilio Perea.

Regarding Pacquiao's, Marquez said the following - "Since the second time we fought (March 15, 2008), he has improved. He shows the teachings of his handler Freddie Roach, with his boxing, his punches are more technical, there is more use of the right hand, and he's matured into an excellent fighter."

"For me, this fight is about pride, about dignity. Everyone knows I was robbed in the two previous two fight. I beat Pacquiao before, and I'll do it again."

He watched the televised feed of his brother Rafael's fight with WBC super bantamweight champ Toshiaki Nishioka, which took place last Saturday in Las Vegas. Juan Manuel is convinced the judges robbed his brother of a win.
