Juan Manuel Marquez believes Timothy Bradley will have another tough night against Manny Pacquiao in their upcoming fight on Saturday at MGM Grand Garden Arena in Las Vegas, Nevada.

Marquez, who is considered as the boxer who gave Pacquiao the toughest fights of his career, is not buying Bradley's assessment on being a new fighter after hiring Teddy Atlas in place of Joel Diaz. Marquez does not think Atlas brought a lot of chances, which makes him convinced that Bradley still needs drastic adjustment if he wants to win.

The Mexican boxing superstar, who fought Pacquiao four times and won via sixth-round knockout in their last fight in December 2012, said that Bradley should be active and not let himself become an easy target for the Filipino boxing icon.

"I do not think there will be many changes, on minor adjustments with new trainer Teddy Atlas," Marquez told ESPN Deportes via BoxingScene. "But he will need to adjust in terms of speed, the speed of his hands and his feet must be moving in the ring and cannot allow himself to be a fixed target for Pacquiao."

Marquez said that Bradley should use a lot of side-to-side movement in order to negate Pacquiao's speed and power.

However, Hall of Fame trainer Freddie Roach expressed confidence that Pacquiao will be ready for what Bradley will bring on the table on fight night. Roach said that Pacquiao is already 100 percent ready for the fight, playing down rumors suggesting that the former pound-for-pound king is dealing with a foot injury.

"His feet is hot because he's moving so much," Roach said via SPIN. "That's been a problem in the past, because we didn't take care of that, we didn't have pads. But the pads will take care of that. It's not a problem."

Pacquiao, who holds a 57-6-2 record with 38 knockouts, will be fighting for the first time since absorbing a unanimous decision loss to Floyd Mayweather in the record-breaking bout in May last year.
