Manny Pacquiao may meet an old foe in a new place in September. Top Rank's CEO Bob Arum says he is trying to put together a fifth fight between Pacquiao and Juan Manuel Marquez and shopping it to casinos in Macau and Singapore.
Arum says the bout would probably be at one of the Venetian hotel-casinos in Macau or Singapore.
"What we're waiting for is which one of their hotels they want to do it at," Arum said over the weekend.
Marquez would be the most likely opponent for Pacquiao, although Arum indicated earlier that Timothy Bradley, who won a disputed decision over Pacquiao last year, was another possibility.
Marquez knocked out Pacquiao in the sixth round in December, flattening the Filipino with a right hand that left him face down on the canvas for two minutes. It was the first win for Marquez in four fights between the two rivals.
If Pacquiao fights Marquez, it could be held far from the Las Vegas Strip, where all four their fights were held.
The MGM Grand would normally be regarded as the most likely venue for the bout, but the hotel is reported to be holding a September date for Floyd Mayweather Jr, assuming he beats Robert Guerrero at the hotel on May 4.
Arum is in Macau this week for a card in which two-time Olympic Games gold medallist Zou Shiming of China will make his professional debut on Saturday night.
