Hey Sai. All the three are great spinners. But with Shande Warne, he has got most of his wkts against England and SA who are the worst players of spin. Shane Warne's against India is very bad. Murali has got more wkts against Bangladesh than Shane. Similarly Prasanna got his good and bad, the way cricket played now a days changed a lot, test runs are scored at an avg rate of 3.00/over, in ancient days it was less than 2/over. So we cant compare any of these greats to each other, all the three are great in their own league. So enjoy the game of cricket.
