Floyd Mayweather Jr. has questioned the actual fighting desire of Amir Khan, the WBA/IBF junior welterweight champion. And Mayweather questioned Khan's ability to sell tickets in the United States. During the last few weeks, Khan and Golden Boy Promotions have been talking up a 2012 mega-bout with Mayweather, who challenges Victor Ortiz for the WBC welterweight title on September 17 at the MGM Grand in Las Vegas. 

“[Khan] don’t really want that; not selling 2,500 tickets and having a bunch of giveaways. No, he don't want that," said Mayweather during an interview with Fighthype.com.

Mayweather went a bit further, and claimed Khan was ducking junior welterweight contender Jessie Vargas (16-0, 9KOs), who happens to be promoted under the Mayweather Promotions banner and fights on the Mayweather-Ortiz undercard against Josesito Lopez.

"Jessie Vargas wants to know why Amir Khan is ducking and dodging. He's asking for him. Everybody is ducking and dodging him. He's my fighter and he wants [Khan]," Mayweather said.
