Floyd Mayweather Jr. made easy work of Robert Guerrero on May 4, defeating the boxer in a unanimous decision.

After winning the 44th bout of his career, Mayweather could get back in the ring rather quickly.

Richard Schaefer, CEO of Golden Boy Promotions, has already begun looking for an opponent for Mayweather’s next fight. He told ESPN he’s hoping to set up a fight between Mayweather and Saul "Canelo" Alvarez.

Schaefer promotes Alvarez, as well as working with Mayweather, promoting his last seven bouts. He’s had talks with both camps and is confident he can make it happen.

"I am working on the fight," Schaefer said. "I'm crunching the numbers. You should see my calculator -- it's red-hot. I am working on a lot of fights, but this is my No. 1 priority."

Mayweather doesn’t have his next fight scheduled, but he announced in late 2012 that he would have two bouts in 2013. His plan was to follow his match against Guerrero with a bout on Sept.14 at the MGM Grand.

Timothy Bradley and Juan Manuel Marquez are already set to face off on that date. However, Top Rank promoter Bob Arum told ESPN the welterweight title fight would be moved if Mayweather decides to go for his 45th win on the same day.

A four-month break is not something Mayweather is accustomed to doing. It has been seven years since he last fought twice in a span of five months.

Alvarez is coming off a win against Austin Trout on May, putting him at 42-0-1 for his career. The fight between the two undefeated boxers could have already been made official. Mayweather, though, declined to sign a deal which stated that the boxers would face one another if each won his last fight.

The biggest issue may be deciding in what weight class the two would participate. Alvarez has stated that he does not want to fight at a weight lower than 154 pounds. Mayweather has gone as high as light middleweight, but never faced an opponent at more than 151 pounds.

Even if Mayweather and Alvarez can’t agree to a fight in September, fans hoping to see Mayweather and Manny Pacquiao fight shouldn’t hold their breath. Pac-Man will go up against Brandon Rios on November 23 in Macau, China.

Pacquiao has asserted that he’s still interested in facing Mayweather. The 36-year-old, however, has scoffed at the notion of fighting a boxer who has lost twice in a row. A Pacquiao victory against Rios is a must if there is any chance of the dream fight happening in the future.

No matter who Mayweather faces, the fight will be a big moneymaker. Sports Illustrated recently named the boxer atop their “Fortunate 50” list. The publications projects he will earn $90 million in 2013 from his two bouts.
