FAMED American trainer Freddie Roach may be belittling Miguel Cotto, but Manny Pacquiao is not taking the Puerto Rican for granted.

This when they slug it out for the world welterweight crown on Nov. 14 (November 15 in Manila) at the MGM Grand in Las Vegas, Nevada.

"I look Cotto as my toughest fight," Pacquiao told Fightnews.com during a media day at the jam-packed Wildcard Boxing Club Wednesday.

Pacquiao acknowledged the fact that Cotto is bigger and younger than him, but the Filipino boxing hero made it clear that he also fears no one.

"I'm not worried moving up in weight. I wasn't worried when I accepted the fight with Oscar De La Hoya and I wasn't worried when I accepted this fight with Cotto," Pacquiao said.

Pacquiao also relishes at the prospect of becoming the first boxer in history to win a seventh crown in different weight classes.

"This fight is about history. It's exciting to think I can be the first person to win seven world titles in seven different weight divisions," he said.
