MANILA, Philippines—Inside a cordoned-off Wild Card gym, Freddie Roach is busy adding yet another component to Manny Pacquiao’s arsenal that he feels Oscar De La Hoya cannot match—consistency.

“The thing is, Oscar has his good and bad days,” the 48-year-old Roach told the GMA News website. “He isn’t sharp everyday.”

And Roach feels that consistency will help tilt the odds in Pacquiao’s favor when the Pacman squares off against a bigger De La Hoya on Dec. 6 in Las Vegas.

“Pacquiao is sharp everyday. He’s consistent. Oscar struggled to work through it at times because of his age. Thing is, when we get older, we get slower. It’s a natural fact and he can’t do anything about it.”

Pacquiao’s training, according to Roach, is in full swing with the Filipino ring icon putting in an average of 34 rounds a day in mitts, shadow boxing and sparring.

While the two-time Trainer of the Year may be generous in volunteering information about the training, Roach said he has completely shut the doors on people who don’t have any direct involvement inside the Wild Card Gym.

“We completely closed the Wild Card Gym,” he disclosed. “Nobody’s been allowed in. I’m asking Manny’s friends to leave. I’m asking my assistant trainers who are not working with this fighter to leave.”

He said he has learned from Pacquiao’s sensational 2005 loss to Erik Morales in first part of their trilogy. Back then, the Mexican legend quietly prepared while the Filipino worked out in the open.

“The only people who are in the gym are the people who have a job—people who are working with Manny, sparring partners, coaches that’s all. When somebody comes in, like HBO, ESPN—obviously they’re the media—they have to make an appointment.”

He added that he only allowed media to get inside during the first day of sparring. HBO, which will carry the fight on pay-per-view, is also filming a 24/7 documentary, a four-part series that will be shown days leading to the projected $100 million mega fight.

“But that’s the last day of sparring anyone will see until the fight because I just want to give them a taste of what Manny’s up to. After this, the succeeding sparring sessions will be closed-door. 100 percent,” he said.

Pacquiao’s cut-throat training has already inspired up-and-coming boxing stars who were lucky enough to witness it.

Edinburgh featherweight prospect Jason Hastie told sportinglife.com that after seeing the WBC lightweight champ at close-range, he was compelled to put extra effort on his own workouts.

“Watching Manny Pacquiao train was unbelievable,” said Hastie, who will fight at Paisley Lagoon Leisure Centre on Saturday. “The intensity that guy trains at is phenomenal. Every round is 100 miles an hour. It has shown me what I need to do to become a better fighter.”

Hastie caught a glimpse of the training on a trip to the famed Hollywood gym last summer.

“It doesn’t matter how much talent you’ve got, or how good you think you are. You can always train harder and be better,” he said.
