Former four division world champion Juan Manuel Marquez has advised his former foe, WBO welterweight champion Manny Pacquiao, to do everything in his power to avoid the possibility of allowing the unification with WBC/WBA champion Floyd Mayweather Jr. to go to the scorecards. The fight is taking place on May 2nd from the MGM Grand in Las Vegas.

Marquez saw his countryman, Jose Luis Castillo, as the rightful winner over Mayweather in 2002 when they fought at the MGM Grand. The judges saw it otherwise, and scored the bout unanimously for Mayweather.

The Mexican veteran, who fought Pacquiao four times and Mayweather once, feels the Filipino boxer must avoid any boxing strategy and come in there throwing firepower with both hands

"Mayweather has the defensive resources, technique, speed and counter-attacks to do a lot of damage to Pacquiao, and I think he will impose [those traits]. I know how judges perform in Las Vegas, as we saw in that fight where José Luis Castillo beat [Mayweather]. However, [the judges] gave it to Mayweather and Pacquiao has no alternative but to knock Mayweather out to end his undefeated record," Marquez told Clarica.
