Next opponent for Mayweather?

After Floyd Mayweather took down Marcos Maidana by unanimous decision and extended his professional record to 47 wins and no losses, the question many boxing fans ask themselves is: Whom will Mayweather fight next? Every time Mayweather steps on the boxing ring, sports betting sites and bookies go crazy, however, at 37 years old, Mayweather is close to the final days of his boxing career. His current deal with Showtime and CBS has two remaining fights, most likely the final bouts of his career.

With only a few fights left, Mayweather must decide if he goes for favorable matchups that will lead to more easy victories, or he can take on the best possible opponents and close his career with a bang.

Let's take a look at who would be a good fit to fight Mayweather next in 2015.

Manny Pacquiao

Manny Pacquiao has to be the first name on this list because this is the match that boxing fans have been waiting so patiently for. The two were nearly set for a bout in 2010; however, it never took place due to differences in the revenue split and the form of drug testing.

Following his victory against Miguel Cotto, there was a lot of demand for a fight between the seven-division world champion Pacquiao the five-division world champion Floyd Mayweather, Jr. Pacquiao reportedly agreed to fight Mayweather on March 13, 2010, however, the bout was put in jeopardy due to disagreements about Olympic-style drug testing. Freddie Roach commented that he would not allow blood to be taken from Pacquiao one week before the fight. In an attempt to resolve their differences, the two went through a process of mediation before a retired judge but Pacquiao refused and instead only agreed to a 24-day no blood testing window.

Kell Brook (33-0)

At only 28 years old, holds notable wins over Michael Jennings, Lovemore Ndou, Matthew Hatton, Vyacheslav Senchenko and Shawn Porter. On October 26th, 2013, Brook faced Ukrainian Vyacheslav Senchenko, winning the fight by K.O and becoming the mandatory challenger for IBF Welterweight Title. Brook was the underdog going into the fight but defeated Shawn Porter to win the IBF Welterweight Championship at the StubHub Center in Carson, California on 16 August 2014 by a majority decision, with the three judges scoring the fight:114-114, 116-112 and 117-111.

Juan Manuel Márquez (56-7-1)

Juan Manuel Marquez is known known for his four fights against Manny Pacquiao, specially for the wild K.O in his last fight againt the Filipino. With just 1 second left in the 6th round, Marquez countered Pacquiao's double jab with a ducking right cross sending Pacquiao face first to the canvas, resulting in a knockout. Pacquiao, who had not been knocked out in over 13 years since his loss to Medgeon Singsurat in 1999, remained unconscious for several minutes. This was named The Ring magazine's "Fight of the Year" and "Knockout of the Year" and "International Fight of the Year" by the British website BoxRec.

Ring Magazine currently ranks Márquez as the number six pound-for-pound boxer in the world and number three in the welterweight division.
