Head coach Ravi Shastri has called Virat Kohli the "boss" of Indian cricket and said the support staff is there to "take the burden off" the skipper.
Batting mastero Kohli has been at the heart of India's world-record 12 Test victories in a row on home soil.
"The captain is the boss, I always believe that. The job of the coaching staff, as far as I'm concerned, is to prepare the guys in the best possible way to be able to go out there and play brave, positive, fearless cricket," Shastri said.
Shastri was speaking to former England captains Nasser Hussain and Michael Atherton and Rob Key during a Sky Cricket Podcast.
"The captain leads from the front. Yes, we are there to take off the burden but you leave him to do his job in the middle. The captain sets the tone and is encouraged to set the tone. In the middle, he controls the show."
"He woke up one morning and said if 'I want to play this game I want to be the fittest player in the world and compete against the best in all conditions' and he let his body go through one hell of a lot."
"It was not just the training but the sacrifices he made with his diet. I could see that change happening all the time. He got up one day and said 'Ravi, I'm vegetarian!'
