He’s currently busy getting Manny Pacquiao ready for a third fight against Timothy Bradley, but Freddie Roach admits there’s a rematch that never leaves the back of his mind.

Roach hopes Pacquiao impressively beats Bradley again Saturday night in Las Vegas and returns for a rematch against Floyd Mayweather Jr. The 37-year-old Pacquiao has said he’ll retire after battling Bradley again to focus on his political career and the 39-year-old Mayweather retired following his easy victory over Andre Berto nearly seven months ago.

Retirements typically don’t last in boxing, though, especially when fighters can return to make enormous sums of money. Las Vegas’ Mayweather (49-0, 26 KOs) and the Philippines’ Pacquiao (57-6-2, 38 KOs) combined to make more than $300 million from their long-anticipated showdown 11 months ago in Las Vegas.

Mayweather won a convincing unanimous decision in a mostly uneventful encounter. Pacquiao claims a right shoulder injury that required surgery several days after the fight hampered him for much of their 12-round match.

“I certainly hope so,” Roach told a group of reporters Thursday regarding a Mayweather-Pacquiao rematch. “I would love for Manny to fight him one more time, 100 percent healthy, which he definitely is right now. I would love to see that, yes.”

Above all else, Roach reiterated he believes money will lure them into a rematch.

“Between him and Manny,” Roach said, “they both have very … Manny’s a very generous person, and gives a lot of money away to his countrymen. And buys poor people houses and builds churches and builds schools, and does good things with it. And Mayweather buys things, a lot of cars and a lot of houses for himself it seems like. They’re both spenders. Sometimes those spenders have to fight again.”

Pacquiao will fight for the first time since Mayweather beat him when he boxes Bradley (33-1-1, 13 KOs, 1 NC), of Palm Springs, California, at MGM Grand Garden Arena (HBO Pay-Per-View; 9 p.m. ET/6 p.m. PT; $69.99 in HD).
