Manny Pacquiao’s coach is confident that the Filipino will beat Chris Algieri on November 22.

Algieri represents a younger, hungrier generation of boxers hoping to take down Pacquiao but Freddie Roach believes the WBO welterweight champion has the speed and skills to retain his title.

The undefeated American earned his shot at Pacquiao, who has held “world” titles in eight weight divisions, by getting off the canvas twice to beat Russian Ruslan Provodnikov on a split decision in June. The victory improved his record to 20-0.

Roach recognises the hard-hitting New Yorker's toughness but says Pacquiao has the tools to retain his title in Macau later this month.

"He's a tough kid and he's strong," Roach told The Philippine Star. "He doesn't have the speed and the skills Manny has. But he has the power."

Pacquiao has assembled a record of 56-5-2 during his 20-year professional career. He has beaten fighters such as Erik Morales, Marco Antonio Barrera, Juan Manuel Marquez, Shane Mosley and Oscar de la Hoya.

He suffered successive defeats in 2012 but got back on track with two impressive wins over Brandon Rios and Timothy Bradley.

A win over Algieri could bring the long-awaited super fight with Floyd Mayweather Jr one step closer.

"A lot of the guys we fought in the past are retired now," Roach said. "We're fighting the new generation. Rios was the first step. And then Bradley. These guys are younger and hungrier."

Pacquiao has not knocked out anyone since stopping Miguel Cotto in November 2009, and was himself knocked out by Marquez in 2012 in his first bout after losing to Bradley.

Some critics have questioned how much gas the 35-year-old has left after 63 professional fights, but “Pacman” will be a strong favourite to beat the 30-year-old Algieri at The Venetian Macao.
