I don't think there is any argument for the #1 spot.  Although I didn't see him playing record shows it is Sir Don Bradman.  After Bradman, it has to be Sachin.  He has record to prove it and even Bradman said once he (Sachin) reminds of him.  I know we all hate India but I’m surprised to see Sachin’s name not listed on many top 5 or 10.
