Shane Mosley has warned Manny Pacquiao not to underestimate him when the two meet for the WBO welterweight title on May 7 next year.
The 39-year-old American fighter is set to pen a deal which will see him attempt to prise Philippine legend Pacquiao's WBO crown from his grasp at the MGM Grand in Las Vegas.
However, with Pacquiao regarded as the best pound-for-pound boxer in the world, not many people will give 'Sugar Shane' much of a chance of winning.
Mosley, though, with lightweight, welterweight and light-middleweight titles picked up during his career, is looking forward to producing a shock.
Mosley, who has lost to Floyd Mayweather Jr and looked disappointing in his draw against Sergio Mora in September, said: "I know that they think I'm an old man and that Manny is going to beat me. Let them think that. I still have power and speed.
"They thought I was done before I knocked out (Antonio) Margarito, too. So they can think whatever they want.
"I know what I can do."
