Juan Manuel Marquez is not expecting any issues by fighting Manny Pacquiao at the catch-weight of 144-pounds. The WBA/WBO lightweight champion is facing Pacquiao for the WBO's welterweight title on NOvember 12 at the MGM Grand in Las Vegas.

Marquez believes the judges robbed him of a victory in their first two meetings, which saw a twelve round draw in 2004 and close split decision win for Pacquiao in the 2008 rematch. Marquez is working with a strength and conditioning coach and building a strong body to overcome Pacquiao's physical advantages in the trilogy.

" I don't think the weight will be a problem. I'm working with people who are going to help me achieve a good weight and raise my speed and strength to win the fight. I thought I won both [of our] fights, especially the rematch. But that's in the past and now were are in the present and on the 12th of November I'm going to leave with my arm raised," Marquez said.

"Everyone knows I'm always well prepared for my fights and this is no exception. For a fight like this we have to work hard and put together a great game plan. I am preparing myself for a great fight and I'm going to win the world championship for Mexico."
