Pacquiao says he needs to reprise old, ferocious Manny

There's cause for concern in the Manny Pacquiao camp these days.

This will be Pacquiao's fourth fight against Marquez, 39, and he has two narrow victories and a draw to show for the first three. If you ask Marquez and many ringside observers of those fights, the ring-smart veteran from Mexico City could be 3-0 and would seem to have Pacquiao's number.

Pacquiao, a congressman in the Philippines who will run for re-election next May and plans a Senate run in 2016, already has said he will spend his entire training camp at trainer Freddie Roach's Wild Card gym in Los Angeles.
