Manny Pacquiao insist he will be too fast for Miguel Cotto when the two men meet in Las Vegas on 14 November. Philippine superstar Pacquiao, who knock out Britain's Ricky Hatton in two rounds in May. My rate is my benefit and what's in the spirit makes the difference.

No matter how much rate he has, when you have a good resistance, you can stop speed, countered Puerto Rico's Cotto, the WBO welterweight champion. I'm going to coach the hardest in my profession. I'm just annoying to get myself fit sufficient to capitalise on any mistakes. Pacquiao, 30, has only fight as high as welterweight once before, next to American legend De la Hoya, and his win over Hatton took place at light-welterweight.

And his coach Freddie Roach approved Cotto, 28, would be Pacquiao's most frightening foe yet. Roach said that I'm receiving Manny prepared for the clash of his life. Pacquiao, who has won world titles in six dissimilar weight divisions, was at ringside in New York in June when Cotto won a choice over Joshua Clottey. Pacquiao said that I'm intimidated and he's physically powerful and he can punch, who has 49 wins and three defeats from 54 fights. I learn the style of my challenger and apply some technique to beat him. I see some weakness in Cotto but I won't tell what I saw.

Cotto's only beat in 35 fights in last year next to Mexico's Antonio Margarito, who was poised after his trainer was found to have burdened his gloves before a January bout against Shane Mosley. Cotto, a previous world champion at 140lb, stopped up Britain's Michael Jennings in five rounds to maintain the vacant WBO welterweight title in February.
