Floyd Mayweather may be facing a tough test against Robert Guerrero on 4 May in Las Vegas but speculation has already begun regarding who the undefeated American will face in the coming 12 months.
The 36-year-old signed a six-fight deal with American broadcaster Showtime in February, leading to plenty of rumours as to who else Mayweather would face. Mexican sensation Saul Alvarez has been strongly linked while there were suggestions that Devon Alexander had already been approached.
With 43 victories already on his resume, it would appear that Mayweather is running out of opponents, especially after he made it clear that former pound-for-pound king Manny Pacquiao was not on his radar.
"Manny Pacquiao got a lot of hurdles to get over to get to Floyd Mayweather," Mayweather told CBS Sport. "He just got two back-to-back losses. I tried to make the fight to happen. The only thing I was asking for was random blood and urine testing just to show the world the sport of boxing is a clean sport."
Mayweather also declared that he would not be moving up to 160lbs to make a megafight with middleweight champion Sergio Martinez.
"Sergio Martinez is 160. Floyd Mayweather walks around at 147," Mayweather said. "Where was Sergio Martinez when I was dominating when I was 21? Nowhere to be found."
One fighter who could now be in line to face the American is former light-welterweight world champion Amir Khan. The Brit was recently handed the number two ranking by the WBC in the 147lb division which increased speculation that he has been hand-picked to face Mayweather.
It would seem that Khan is positioned for a shot at the WBC crown which will be on the line when Mayweather faces Guerrero in May, despite the former Olympian never having fought in this weight class.
Many believe Golden Boy Promotions have helped persuade the WBC to give Khan this ranking as the British fighter remains hugely popular on American soil and would guarantee another huge pay-per-view event.
The 26-year-old faces Julio Diaz in Sheffield on April 27 and has been guaranteed a shot at unifying the light welterweight division by Oscar de la Hoya.
"Golden Boy said they are going to do a mini tournament. It's going to be [Danny] Garcia - [Zab] Judah, the winner fights the winner of [Lucas] Matthysse and [Lamont] Peterson, and at the end of the year the winner of that fights me," said Khan.
"The reason they fight me at the end is because I can't fight in the middle because I've got Ramadam. Hopefully, we'll know by the end of the year who the best 140 pound fighter is and that's going to be between the five of us."
This suggests that Khan could be in line to face Mayweather in 2014, as long as he becomes the undisputed champion at 140lbs.
Khan has always stated his intent to one day share a ring with Mayweather and should he manage to win his next two contests then he may well finally land that elusive opportunity.
