The Filipino fighter's coach Freddie Roach has disclosed his "secret weapon" to be used in the upcoming fight while HBO has announced the Manny Pacquiao and Floyd Mayweather pre-fight documentary.

According to On The Ropes Boxing Radio, Roach said that he got all the guys he wanted to be the sparring partners of Manny to be able to defeat Floyd Mayweather.

"I brought some great young kids to box, I've got too many actually, I got six really good guys that all look like Mayweather and I have one that I'm gonna use in the last two weeks is one that used to work at Mayweather's gym and was part of Mayweather's camp," said Roach.

"He does the style really well, he's my secret weapon right now," he added.

Roach reportedly said that his "secret weapon" is currently staying at his house and they have already discussed about the strategies that Manny will use in the upcoming fight.

He added, as well, that Manny Pacquiao's legs are solid compared to Mayweather.

"Mayweather, if you watch his two last fights, he says he's on the ropes because he wants to exchange and make the fans happy, I don't believe that, I believe that he has to go to the ropes to rest a little bit because his legs are a little short," he said.

Meanwhile, as the fight of the millennium between Manny Pacquiao and Floyd Mayweather is scheduled on May 2, HBO is reportedly set to show the pre-fight documentary.

Newsday reported that HBO will chronicle Pacquiao's journey in "Mayweather/Pacquiao: At Last." HBO Sports executive producer Rick Bernstein reportedly said in a statement that the documentary will show how the fight came to be and how Team Pacquiao prepares for the upcoming fight.

The one-hour special pre-fight documentary will premiere on Saturday, April 18, around 11:45 p.m. ET, following the HBO's "Boxing After Dark" doubleheader.
