Boxing's pound-for-pound champion Floyd Mayweather Jr. will let boxing fans decide who will be his next opponent on May 3 at MGM Grand Garden in Las Vegas, Nev.

Mayweather, who won world championships in five different weight division and is universally recognized as the best boxer on the planet, posted on his Twitter the photos of Great Britain's Amir Khan and Argentina's Marcos Maidana as his top contenders for his Cinco de Mayo event.

"I'm going to let the fans vote. Tell me who I should fight next. Khan or Maidana?," tweeted the 36-year old Mayweather, who is coming off sensational victories over Welterweight contender Robert Guerrero and Middleweight poster boy Saul Canelo Alvarez last year.

Khan vs. Maidana for Mayweather

Khan and Maidana already fought each other once in their careers with the Briton grinding out a unanimous decision victory over the Argentine brawler in 2010. Despite the loss, Maidana made a furious rally towards the end of the match and even put Khan on the brink of absorbing another knockout loss.

Since then, Khan suffered defeats at the hands of Lamont Peterson and Jr. Welterweight kingpin Danny Garcia. Last June, Khan barely outpointed Mexican veteran slugger Julio Diaz in a non-title bout in Sheffield.

On the other hand, Maidana has been on a roll since his loss to Khan as he won six of his last seven fights, including victories against Mexican legend Erik Morales, welterweight contender Jesús Soto Karass, and recently pound-for-pound rising star Adrien Broner.

Several months ago, Khan emerged as the clear-cut favorite to take on Mayweather Jr., but the sensational win of Maidana over the previously undefeated Broner in their WBA Welterweight fight last December catapulted him as an intriguing opponent for Money May.

Ricky Hatton's View

Hatton, who fought and lost to Mayweather Jr. via 10th round KO in 2007, believes Khan will eventually be picked to fight Mayweather because of his huge fan base in the United Kingdom.

"You've got that United States vs. Great Britain rivalry, you could do it in Vegas, and when you look at the fighters available the best name out there is Amir Khan," Hatton said to Talksport. So I think it will happen. And I do give Khan a chance...Styles make fights...He's probably the only man who can match Floyd for Khan."

Maidana might be the hotter boxer right now on paper, but Khan's followings will convince Mayweather to fight the Briton because of the financial windfall that it provides, stressed Hatton.
