Ravichandran Ashwin
In the absence of Ravindra Jadeja, Ravichandran Ashwin is expected to play in all four Test matches. Being the senior spinner he will have a huge role to play in the Chennai wicket which historically have been favoring the spinners.
Ashwin will have enough opportunities to go for wickets and will be a tough proposition for the opposition batsmen. He is on 377 wickets currently is has a good opportunity to inch closer to the 400-mark.
