As far as the current Indian coach Ravi Shastri's performance is concerned, he has done a phenomenal job till date, along with his assistants, Sanjay Bangar (batting coach), Bharat Arun (bowling coach) and R Sridhar (fielding coach).
Out of the 32 series played under him, India have managed to win 23 of them, while only a couple of them have ended in a draw.
Shastri replaced Anil Kumble under controversial circumstances
Prior to Shastri, it was Anil Kumble who held this coveted post. However, skipper Kohli had reservations against his style of coaching. This dressing-room conflict between Kohli and Kumble soon turned into a public spat, which led to Shastri being appointed as the new coach.
