Amir Khan's win last Saturday night over Devon Alexander opened up the possibility that he would get his long-awaited fight with Floyd Mayweather, but Mayweather says that he's not interested in Khan right now, and that Manny Pacquiao is his sole focus.

"The other night I think he did 4,000 (attendance), so, Amir Khan, his name holds no weight," Mayweather said. "No one knows who Amir Khan is except people who are involved in boxing. My focus is Manny Pacquiao. Let's make it happen."

Khan (30-3, 19 KO) has argued that with the British audience he can bring to the fight -- particularly on pay-per-view there, which means a good chunk of money -- makes it a big fight. And for whatever it's worth, Khan-Alexander did an officially announced attendance of 7,768 at the MGM Grand in Las Vegas.

Mayweather (47-0, 26 KO) has fought guys like Robert Guerrero and Marcos Maidana in the last two years who weren't exactly big draws by themselves, either, so that criticism seems a little odd. Unless, that is, Mayweather is truly looking to make the Pacquiao (57-5-2, 38 KO) fight happen. And Floyd says he's serious.

"Bob Arum and Manny Pacquiao have been fooling the public for years," he said. "I never spoke about the fight. Years later, I've finally decided to speak about the fight. Basically, the first time we didn't fight because of random blood and urine testing. Second time we didn't fight because he didn't want to take the $40 million. Now, I don't know, Bob Arum is trying to throw another excuse out there, about they don't want to fight May 2nd. Why not? Let's make the fight happen."
