Two days before the fight, Mike Tyson dropped by by the IBA Gym in Las Vegas to catch the Filipino’s last training session before the fight.

As if words were not enough to drive his point across, former undisputed heavyweight champion 'Iron' Mike Tyson stepped back, bobbed, weaved and then ducked a phantom left hook.

This is how you do it against Oscar De La Hoya, Tyson told Manny Pacquiao’s assistant trainer Buboy Fernandez.

“He (Tyson) said Manny must keep moving the head,” Fernandez said.

Tyson also noted that De La Hoya’s background as an amateur fighter makes him a deadly tactician.

“He wants Manny to move in and not to back away too far because that’s where Oscar’s jab-straight-hook (combination) comes to play,” Fernandez said.

He also quoted Tyson as saying it would be best for the Filipino ring hero to keep attacking De La Hoya’s body because sooner or later the Golden Boy’s guard would start to lower.

Tyson came in a pink long-sleeved shirt, gray pants and black leather shoes, and accompanied by a lone friend. He sat quietly in the gym's weights section, obliging to some photo-ops and only rose when Pacquiao got up the ring.

Tyson watched with great interest as the world's pound-for-pound champion from the Philippines pounded the mitts with Freddie Roach, who also trained the boxer that was also known as "the baddest man on this planet" late in his career.

He applauded when Pacquiao was done with the mitts, then started to share his thoughts with Roach and co-trainer Buboy Fernandez, showing them how to move the head and body or dock and weave against the taller and heftier Dela Hoya.

Mike Tyson appeared as a hologram along with other former champs George Foreman, Joe Frazier, Evander Holyfield and Lennox Lewis, and got the biggest receive of them all.
