Roach, who is on the poorest run of recent career following two straight losses for Pacquiao and defeats for Julio Cesar Chavez and former fighter Amir Khan, believes that the decision by the ‘Pacman’ to look overseas for future bouts means a Mayweather clash is further away now than ever.
“The one thing about Mayweather is he will never fight anywhere but Las Vegas. He made that clear in the past when we were in talks,” Roach told Sport360.
“So I don’t think a fight between him and Manny could ever happen anywhere but the States.”
Pacquiao, 34, is eyeing up alternative venues for his April fight after promoter Bob Arum stated that the Filipino was disillusioned with the American tax hike for higher earners and venues in Singapore, Dubai and the Philippines are thought to be on the considered list.
The eight-weight champion is due to warm up for a possible fifth meeting towards the end of the year with arch-rival Juan Manuel Marquez after a devastating knockout at the hands of the Mexican 140lb titlist in December last year.
