Arum told the Bulletin that the Luneta or Quirino Grandstand will be the first stop of a four-city press tour on Sept. 3 and that he expects a multitude to attend the event in Manila.
A similar function will be held in Marquez's lair in Mexico City after stops in New York and Los Angeles, according to Arum, revealing that the main square called The Zocalo, which can hold more than 100,000 people, will be tapped to host it.
After the tour, Pacquiao and Marquez will head to their respective
high-altitude training camps: Pacquiao in Baguio and Marquez in Toluca.
There is bad blood in this third meeting between Pacquiao and Marquez with their first two matches ending in controversy. The first time they fought, the bout ended on a 12-round split draw and the rematch ended on a split decision victory for the Filipino.
Marquez remains bitter up to his day, telling Mexico City-based journalist Tim Johnson of the McClatchy newspapers in an article that appeared in the Sacramento Bee that "he (Pacquiao) knows he's never really beaten me."
Both fighters insist there'll be no fourth fight as the convincing result of the rubber match will prevent one from taking place.
Nacho Beristain, the newly-inducted Hall of Fame trainer of Marquez, said Pacquiao's metamorphosis from a wild-swinger to a more skillful puncher will make it a lot easier for his fighter to connect.
But Freddie Roach, who will join Beristain soon, said the added weight and the vast improvement will spell the difference.
Roach said Pacquiao will hand Marquez a devastating knockout loss.
Pacquiao and Marquez are fighting at a catch weight of 145 lbs.
