Freddie Roach is not worrying too much about Manny Pacquiao's next fight, as the Hall of Fame trainer expressed confidence that his fighter will dominate Chris Algieri in their upcoming showdown.

In an interview with Tha Boxing Voice, Roach predicted a knockout win for Pacquiao in his World Boxing Organization welterweight title defense against Algieri on Nov. 22 at the Venetian Casino & Resort in Macau.

"We'll knock him out somewhere along the way," Roach said when asked to predict the outcome of the Pacquiao-Algieri fight.

The veteran trainer added that he was surprised when Top Rank Promotions CEO Bob Arum pick Algieri as Pacquiao's next opponent. According to Roach, Arum told them that Algieri earned a shot after scoring a split decision win against Ruslan Provodnikov in June.

"You have to ask Bob," Roach said when asked about picking Algieri for Pacquiao. "I have no idea why he picked that guy. He told me that he beat Ruslan, and he's a good fight for Manny and that was it."

Algieri holds a perfect 20-0 record with eight knockouts. The 30-year-old had a lot of success with his effective jabs in his first 20 fights, but Roach said that Pacquiao won't have a problem dealing with the reigning WBO light welterweight champion.

The 54-year-old trainer insisted that the difference between the Pacquiao and Algieri's skills is like "night and day" and that the Filipino boxing icon is "way above" the Huntington, New York native in terms of talent.

But while he is confident that Pacquiao will run away with a comfortable win, Roach said that he will train Pacquiao as hard as before in their five-week camp in the Philippines and one-week training in Macau.

When asked if he believes that Pacquiao will be as aggressive as he was during his previous fight in Macau against Brandon Rios, Roach said: "Well I hope so because he kicked the sh*t out of Rios. The problem with Rios is, he is a punching bag. It was a great win and we'll see. Manny is coming down to a catch weight of 144 and he might be a little bit of a better punch at the lighter weight."
