MANILA, Philippines – Floyd Mayweather, Sr. has always chosen Manny Pacquiao’s opponents to prevail over the pound-for-pound king, but the Filipino boxing icon always proved him wrong.

Not this time, though. Floyd Sr. predicted that his son, the undefeated Floyd Jr., will outpunch Pacquiao.

“Pacquiao could never beat something that came out of me,” Floyd Sr. told FightHype.com.

The outspoken trainer said Oscar de la Hoya, Ricky Hatton and Miguel Cotto would get the better of Pacquiao, but the seven-division world champion conquered them instead.

Floyd Sr. was the trainer of Hatton for his fight against Pacquiao.

“With Pacquiao, it’s not even going to be a figuring out process. Pacquiao is terrible, man. The man don’t move his damn head, he jumps straight in,” commented the elder Mayweather.

“Lil Floyd hasn’t taken any damage in the fight game and Pacquiao knows he is fighting a different animal; ain’t going to take no damage,” he added.

Mayweather (40-0, 25 knockouts) and Pacquiao (50-3-2, 38 KOs) are slated to clash on March 13 in the battle between the world’s top ranked pound-for-pound fighters. It was reported that a press conference on January 11 will officially announce the fight and its details.

Pacquiao’s World Boxing Organization (WBO) welterweight title will reportedly be at stake. It was also reported that both fighters agreed to a 50-50 purse split.

Pacman shrugs off Floyd Sr.'s comments

Pacquiao, meanwhile, refused to get himself dragged into a "war of words" with the Mayweathers.

That's just not his style, said the reigning pound-for-pound king ang current World Boxing Organization welterweight champ.

"I don't wanna say trash talks.... tahimik lang ako siguro," Pacquiao said during the official opening of his memorabilia shop in Manila.

In fact, Pacquiao has nothing but good words for Floyd Jr.

"Mabilis at malakas din [si Mayweather], siyempre dati siyang Number 1 pound-for-pound," said the Filipino boxing star.

When asked about his choice of site where the fight should be held, Pacquiao said he would still pick Las Vegas.

"Kahit saan, basta Las Vegas," he said.

His wife Jinkee is concerned about her husband's choice of fight date with Floyd Jr. Both camps have reportedly agreed to have the fight staged on March 13, which is just three months away.

"Parang nakakatakot kasi maaga pa so mas-okay siguro kung May," said Jinkee.

She, however, said it is still Pacquiao who has the final say regarding such matters.

"Sabi niya siya ng nakaka-alam sa sarili niya," said Jinkee.

Khan as sparring mate

Pacquiao’s trainer, meanwhile, talked about his plans for his ward’s upcoming training.

Freddie Roach said he wants World Boxing Association light welterweight champion Amir Khan to be Pacquiao’s sparring mate in his training camp for the Mayweather bout.

“Amir's speed is good for Manny, and Amir is the only guy who can keep up with Manny in the gym. When they train, they are like machines,” Roach told The Daily Mirror.

Khan, who is also coached by Roach, sparred with Pacquiao before the Filipino boxing great took on de la Hoya and Hatton.

Moreover, Roach said he wants Khan to fight in the Pacquiao-Mayweather undercard. “Amir would be ready by March, no problem, for another world title defense.”

Khan recently defended his WBA title against Dmitriy Salita by technical knockout in Round 1.

“There are a lot of big names for him now, here in Britain, and in the States. [Juan Manuel] Marquez is one, while [Jose Luis] Castillo is making a comeback and has told me he wants to fight Amir,” Roach continued. “The only guy I don't want him to fight is Manny.”
