Amir Khan has laughed off claims from Floyd Mayweather that he is not a big name and believes the undefeated American could be running scared.
Khan marked his Las Vegas debut on Saturday night with a convincing win over Devon Alexander at welterweight and wants to take on Mayweather in May.
But the WBC and WBA champion is talking up a super fight with Manny Pacquiao instead and was quoted as saying: "No one knows who Amir Khan is."
Khan said, "I want the fight, but is Floyd going to take the fight? Is Floyd going to give me that chance? That's something we're all waiting to hear from Floyd Mayweather.
"I've been asking for the fight for the last two or three years. Now he needs to come back to the press and say, 'I want the fight with Amir Khan'.
"I know I'm touching distance away from that super fight. I think I've proven myself many times and I think this time I've proved myself in the biggest way so he has to take the fight. What else do I have to do?
"I have a bigger name than (Marcos) Maidana did or Victor Ortiz. I'm one of the biggest names in boxing.
"I know if I can bring Floyd Mayweather to Britain then I'll sell out Wembley Stadium. How big does he need my name to be?
Khan, meanwhile, is to donate the shorts he wore in beating Alexander to raise money for the school in Pakistan where 132 schoolchildren were shot dead by the Taliban on Tuesday.
The shorts have 24 carat gold thread woven through the waistband and cost around £30,000.
Khan, who is of Pakistani heritage, said: "I'm going to be donating them towards what happened in Pakistan. I want to rebuild the school and strengthen the security over there."
