Floyd Mayweather Jr has suggested that Amir Khan is not a big enough draw for him to fight at some point in 2012.

The unbeaten American has spoken out to put the brakes on Khan's recent revelation that he wants to step up a weight division to face him inside the next 12 months.
However, after witnessing the 24-year-old British fighter add the IBF belt to his WBA light welterweight crown thanks to a recent fifth-round TKO victory against Zab Judah in their unification fight in Las Vegas, Mayweather questioned Khan's pull in the United States following a disappointing attendance on the night.
Mayweather suggested that Khan should face the likes of Jessie Vargas before him to prove he is the real deal in the eyes of US fight fans.
On the prospect of Kahn fighting him next year, Mayweather said ""He
[Khan] don't really want that; not selling 2500 tickets and having a bunch of giveaways.""
