Manny Pacquiao became an overnight star in the boxing world when he dropped, dominated, and ultimately stopped the great Marco Antonio Barrera of Mexico. It was a tremendous display of speed, skill and power by Pacquiao, whose name can now be found in many pound for pound top ten lists.

Such are the ghosts that this Pac-Man will be attempting to gobble up on Saturday night.
