Former four division world champion Juan Manuel Marquez is pleading with Manny Pacquiao to forget his pursuit of a rematch with Floyd Mayweather Jr. and to focus his energy on other opponents.

Last Saturday night at the Thomas & Mack Center in Las Vegas, Pacquiao claimed the WBO welterweight title with a twelve round decision over Jessie Vargas. Mayweather was sitting at ringside and cheering Pacquiao on.

They fought last May, with Mayweather winning a twelve round decision. There are whispers now that a rematch is being discussed, possibly for May of next year.

Mayweather retired from the sport last September and he's not indicated any serious intention to fight again - although he admits the door is open for the right offer. A rematch between Mayweather and Pacquiao would be the biggest fight, financially, in boxing.

Marquez believes a rematch would end in the same manner, with Mayweather winning a clear points win. He also expects the rematch to play out in the same way as the first fight, with Mayweather sticking to his defensive game plan and not engaging.

"It would be more of the same. Mayweather boxing, and you saw Manny Pacquiao was more eager, had more power, but did nothing. Imagine if it happened right now where Floyd Mayweather could adjust, it would be a fight [that would send boxing] further back, a boring fight," Marquez told ESPN Deportes.

"I think it would be more of the same and fans want to see the Manny Pacquiao from five years ago... aggressive, with that power, searching for good opponents - but we hardly see him anymore. There are fights that are more competitive, good fights. Fans want to see Pacquiao against Keith Thurman, Pacquiao against Danny Garcia, Pacquiao with Terence Crawford - but the promoters will have to do what benefits everybody."
