British star Amir Khan (31-3, 19KOs) is starting to have his doubts about landing a lucrative fight with WBC/WBO/WBA welterweight champion Floyd Mayweather Jr. (48-0, 26KOs), who returns on September 12th at the MGM Grand in Las Vegas.

Khan has been in hot pursuit of this match for the last two years. He even called up Floyd's father and trainer, Floyd Mayweather Sr., to discuss the scenario of fighting his son in the fall. Their phone conversation became very hostile, with Mayweather Sr. erupting over certain comments made by Khan in the press.

Khan feels the older Mayweather came off as a person who was very worried.

"To be honest, I don't believe he wants the fight. He's really worried. I spoke to his father not long ago and he was very worried as well, coming up with any excuse not to fight me. He said I lost fights. Obviously the best have lost fights....Muhammad Ali, Mike Tyson. It's how you come back from losses. I've come back from losses and put myself in position again to fight for world titles and big names. So it seems to me that they are really worried and they are not looking to fight a style like mine, because they know it's going to be a tough fight," Khan told BoxingScene.com/Be Real TV.

"His father said he's going to take an easy fight and Floyd himself said he was going to take an easy fight. If he really believes that it's an easy fight then take it [with me], let's do it. But I don't really believe he wants it because he wants to take an easy route. He wants to take an easy route and avoid Amir Khan."
