I don't think Australia will win the final test though since I am expecting a draw or Indian win. Let's see what happens.
The result in the fourth test cannot be said for sure, but if the Indian team can use Ravichandran Ashwin and Jadeja properly then it will be great for the Indian team. But the Indian team and the Australian team have understood very well that the venues in India depend on the spinners. Ashwin, Jadeja, Lyon, Trodd Murphy, Kuhnemann these five spinners have performed brilliantly in the first, second and third Tests. So the fourth match will depend on these five bowlers. The team that performs best will win the fourth test. But the chances of a draw are very low.
