Manny Pacquiao’s trainer has revealed part of the Filipino’s strategy for the fight against Floyd Mayweather in Las Vegas on May 2.

"Mayweather is a counter puncher and we have to attack really quick and get out really quick," Freddie Roach said in Hollywood on Wednesday.

Roach rejected allegations by Mayweather that his fighter was reckless. "Manny is not reckless at all," said Roach, who has worked with 31 world champions in his Wild Card gym. "Everything we do is planned out and it's part of the game plan.

"We've had a very good training camp. I've never seen Manny at this level. He's really motivated for this fight. It has really escalated his performance. I think he's faster than ever and he's definitely hitting harder than ever."

Pacquiao, appearing relaxed and confident, expressed hope that the defence-minded Mayweather would show more aggression.

“I haven’t really seen him have this much speed and power in a long time,” Roach said. “My chest hurts really bad right now. You can see how much it means to him. He lives for these huge moments, and he knows what this fight means. Floyd is in trouble.”
