(CNN) -- Manny Pacquiao's trainer wants the Filipino fighter to take on undefeated Floyd Mayweather Jr following Saturday night's one-sided win over WBO welterweight champion Miguel Cotto in Las Vegas.
Pacquiao joined the American as one of only five boxers to win major titles at five different weight divisions, and a clash between the two should resolve any dispute as to who is the best pound-for-pound fighter.
"The whole world wants to see him fight Mayweather, and I want Mayweather," his trainer Freddie Roach said.
The 30-year-old, however, was less forthcoming about his future plans following the fight, saying he would let his promoter Bob Arum of Top Rank deal with it.
"My job is to fight in the ring and I think that depends on Arum, my promoter, to negotiate that fight," Pacquiao said.
"I'm just going to take a vacation first and spend time with my family and have fun."
Pacquiao, who started his career at 107 pounds but was up to 144 against Cotto, did indicate that he will not be moving up to another weight.
"For me, I think this is the last weight division I'm going to fight in and I think my trainer will be happy to hear that because 154 is too big for me and 147 is my regular weight," he said.
Legendary trainer Emanuel Steward, who was covering the fight for U.S. broadcaster HBO, said that the public wanted to see Pacquiao take on Mayweather, who returned from a 21-month retirement in September to defeat WBA and WBO lightweight champion Manuel Marquez in a non-title bout.
"There's no doubt you have to go with Mayweather," Steward said on-air. "When you have a fight that's been made by the public more than the fighters, that's what happened with Tommy Hearns and Sugar Ray Leonard. The public said we want that fight to happen and that's why it happened.
"I think they'll come together on the money, but it's going to be a very intriguing fight because Floyd's a technical fighter. He knows how to wait back and box a little bit and it's going to be a lot different than it was against a guy who comes forward and is not that great on his defense.
"But I think it will happen, it's just a case of when and who gets what in terms of money. I think it should be a 50-50. Manny has earned his position as an attraction and to me not just as pound for pound but as one of the all-time greats. I'd put him up there with the Ray Robinsons and Alis."
