WBA junior middleweight champion Floyd Mayweather Jr. (43-0, 26KOs) admits that he's considering the possibility of retirement because his options are running low in terms of potential opponents. At the moment, Mayweather says his mindset is "80-20" in favor of hanging up the gloves.

"There really isn't anybody out there for me to fight. So I really don't know where my career is going to go from here. There is nothing [left] but the young pups, the strong young pups coming up. And they are probably going to try to build a young guy [for a fight with me]," Mayweather said.

Mayweather, 35-years-old, won a twelve round unanimous decision over Miguel Cotto on Saturday night at the MGM Grand in Las Vegas. For the first time in many years, Mayweather was involved in a toe to toe war.

"I've been feeling like [I wanted to retire] before this fight. Like I said before, if it is my last my fight at least I gave the fans [what they wanted]," Mayweather said.

There are several possible options in Golden Boy's stable, but none of those options are ready for a fight in the fall. British star Amir Khan is one consideration. Khan is scheduled for a rematch with WBA/IBF 140-pound champion Lamont Peterson on May 19th. If Khan prevails, he wants to test the waters at 147 with at least one or two fights before a potential Mayweather meeting.

The other option is WBC 154-pound champion Saul "Canelo" Alvarez (40-0-1, 29KOs). Alvarez and Mayweather have been paired on two consecutive HBO pay-per-views and it's obvious the fight is slowly being groomed for a future date. However, Alvarez is not ready to face Mayweather in the fall and plans to headline his own HBO pay-per-view on September 15th at the MGM Grand.

"Canelo is a helluva fighter. I watched him fight Mosley," Mayweather said. "He's rock star in Mexico and the goal is to make him a rock star in America."

The biggest fight in boxing is Mayweather vs. Manny Pacquiao. The Filipino superstar is scheduled to fight on June 9th against Timothy Bradley. Provided Pacquiao wins, he would return in the fall. There are several issues in making Mayweather-Pacquiao, but the biggest issue appears to be the monetary split.

"I went to Pacquiao and offered him $40 million dollars. I called him and talked to him direct. I offered him $40 million dollars and said that I would wire him $20 million in 48 hours. He turned me down. He basically said [that he wants] 50-50. I said 'how can you say that you for 50-50 when you are not doing the same [pay-per-view] numbers that I'm doing.' If you go back and read the article, he said that he would do [the fight] for less [money]. Then he said he wouldn't take the random blood and urine tests, so its just been a problem trying to make this fight," Mayweather said.
