Touring australia and facing them is very difficult. Doni is in experience in captaining the team against australia. no douubt he will lead team india in future. he needs to be groomed. hence i would prefer ganguli as captain and dhoni as vice for a year with a clear instructions to ganguli that he should groom dhoni. after a year dhoni should have been made a captain of indian cricket. no need to name one captain for ODIs and another for tests. this arrangement would have helped india to reach more heights.
