India play an exotically talented Australia on May 7, and then run into Chris Gayle's [ Images ] West Indies on May 9. They need to win one of these two games, as they have the comfort of playing a relatively weaker opponent in Sri Lanka on May 11 in St Lucia.
Dhoni might have tried different combinations in the group matches, but he would have to have his best men on the park if he aspires to get the better of Australia and West Indies.
