Floyd Mayweather vs Canelo Alvarez is 'close' for May 4, says Alvarez

Canelo Alvarez said tonight on his official Facebook page that a May 4 fight with Floyd Mayweather is "close," meaning that we could be seeing what is now arguably boxing's biggest-money fight come to life on what has become the biggest fight date in the sport annually.

Mayweather (43-0, 26 KO) recently announced intentions to fight on May 4 and September 14 next year, but it was also no secret that Alvarez (41-0-1 30 KO) and Golden Boy wanted that date for the 22-year-old Mexican phenom, whose popularity has soared over the last couple of years.

A fight between the two -- which could unify the WBA (Mayweather) and WBC (Alvarez) titles at 154 pounds -- would be absolutely massive, and it is now the biggest fight Mayweather can make, more likely than not. It's easily the biggest fight Alvarez can make.

Robert Guerrero has also been pushed by Golden Boy as a potential Mayweather opponent, but with all due respect to Guerrero, that fight's just not in this fight's league right now, in terms of marketing and money to be made.

Nothing is official (far from it, in fact), but the talks appear to have intensified, and no matter which way it goes, Mayweather likes to take his time promoting a fight, so we could know within the next couple of weeks what he'll be doing on May 4.
