Floyd Mayweather Jr. Believes that Amir Khan has been "talking big" by saying that he deserves a fight against him. However, the champion boxer has said that Khan has not yet proved himself worthy enough.

Mayweather asked Khan to prove that he deserved to be in the same ring with him. He said that the British boxer would have a chance to do so when he would face Devon Alexander on Saturday. Mayweather said that he was aware that Khan had been claiming that he deserved a fight. However, Mayweather, unbeaten in 47 professional fights, said that it would not be possible to fight every fighter who fancied a chance at his world titles. He said that he would have to fight into his 60s if he accepted every challenge.

Mayweather insisted that Khan should prove himself in the ring instead of "talking big." The U.S. boxer said that it was "talking big" on Khan's part to claim that he should be "talked about in the same breath" as the five-division world champion if he managed to defeat Alexander. However, Mayweather indicated that Khan would not impress him with his talking only. "I like the fact the kid has confidence," Daily Mail quoted Mayweather, "But I don't take much notice of words like that. I do all my talking in the ring - maybe he should do the same." Mayweather said that he had not decided whom he would fight next. Mayweather, whose last fight was against Marcos Maidana in September, also said that his decision about his next fight would not be affected by anybody's "big words." However, he said that he would be "watching Amir with interest on Saturday."

Khan, in the meantime, said that he would not have Mayweather on his mind on Saturday while fighting against Alexander in Las Vegas. Even though he apparently fancies a chance to fight Mayweather in 2015 if he turns out to be a winner on Saturday, he may still have to wait for the American champion's green signal. The British boxer, who turned 28 on Monday, said that he was aware that his fight against Alexander would be a "dangerous" one. That is why he is not willing to think beyond even though winning it "could lead to a massive fight" against Mayweather. The Telegraph quoted Khan saying that every welterweight fighter would want a fight against Mayweather.
