LAS VEGAS: Freddie Roach said he has devised an elaborate strategy that will deliver a decisive victory for Filipino icon Manny Pacquiao in his ‘Fight of the Century’ against Floyd Mayweather.

The revered trainer said he expects a bulked up Mayweather to seek an early rounds knockout but warned Pacquiao would be ready to go the distance if necessary.

“He (Mayweather) put on a lot of muscle for this fight. I think he will come out in early rounds and try to knock us out.

“He could also run all night. I have fallen asleep at a couple of his fights before. So I am ready for whatever he brings to the ring.”

Pacquiao set up his training camp for the richest fight in boxing history in a private facility built underneath Roach’s Wild Card Gym in Los Angeles.

They gutted the old laundromat that was there and replaced it with a de facto war room where Roach and Pacquiao have been crafting the plan they believe will end Mayweather’s unbeaten record. Roach said the new gym allowed Pacquiao to escape the clamour and chaos of the Wild Card that comes with having the Filipino superstar training there.

“I blocked the gym off and we kept it private. This camp I didn’t have Manny trying to perform for an audience, he was performing for himself,” Roach said.

“We had a good training camp. A lot of good sparring partners. We had eight sparring partners and we switched them up.

“Manny is too nice to his sparring partners all the time. Once he got too friendly with them we got a new one. That is why we used so many sparring partners.”

Pacquiao wound down his training with a “light” run on Thursday morning followed by another low-key workout in the afternoon, Roach said.

“We are not focused on one strategy but two or three strategies,” Pacquiao said earlier in the week.

Roach said the Pacquiao camp is going to use Mayweather’s fights against Zab Judah and Oscar De La Hoya as a blueprint for what they want to achieve in the ring.

Mayweather beat Judah by a unanimous decision in 2006 and De La Hoya by a split decision a year later.

Roach said if De La Hoya had continued to use his jab effectively in the later rounds he could have beaten Mayweather. Mayweather’s trainer, Mayweather Sr., said Thursday the gloves issue reflected fear in the Pacquiao camp.

“The gloves are not an issue. They ain’t got nothing but fear,” Mayweather Sr. said.

Roach believes Mayweather’s 38-year-old legs may not be as elusive as they once were.

“I don’t think his legs are there anymore. He can’t move like he used to. We will catch him,” Roach said.

“If he wants to rest on the ropes we are ready for that."
