According to WBA 'regular' welterweight champion Keith Thurman (25-0, 21KOs), there is no way that Amir Khan deserves the right to face Floyd Mayweather Jr. in the fall.

Khan is pushing hard to get Mayweather on September 12th at the MGM Grand in Las Vegas. Thurman, and IBF welterweight champion Kell Brook, are also attempting to get Mayweather on the date. Thurman has no problem with Brook getting the call, but he doesn't like the idea of Khan gaining that opportunity.

He says Khan has not done enough as a welterweight to earn that type of opportunity.

Thurman also hit back at Khan's trainer, Virgil Hunter, who recently questioned the chin resistance of the dangerous puncher.

"I think [Khan] is better offer trying to get a Danny Garcia rematch or something like that.  He didn't talk about me after the [Chris Algieri] fight on television. He talked about Floyd," Thurman said.

"But then when one of you guys came and asked him some more questions, then he decided to say my name out of his mouth - and then for some reason his coach wanted to talk junk too. I don't know what that's about because Virgil can't throw punches for Amir, he can' take punches for Amir - and if I have to I'll knock both of them out."

"He does not deserve his ranking in the welterweight division. What top welterweight has Amir Khan beat?"

Thurman is back on August 1st in Florida, when he takes on Luis Collazo - who Khan dominated last May in Las Vegas.
