#1 Gary Kirsten
After India's exit from the 2007 World Cup in the first round and the resultant end of Greg Chappell's tumultuous reign as national team coach soon after, the team had no coach for quite a long time.
In 2008, one of the finest openers of the 1990s and the early-to-mid-noughties, Gary Kirsten of South Africa was appointed as the full-time coach. During his time as the coach, India's record improved in all formats of the game and performances in Test cricket improved considerably.
He complemented captain MS Dhoni well, and helped India reach the top of the ICC Test rankings. In fact, Dhoni had remarked that Kirsten was the best thing to have happened to the national team.
Kirsten fine-tuned the technique of many batsmen and worked behind the scenes without hogging the limelight, unlike his predecessor. His tenure ended with one of the Indian cricket's (and his own) greatest moments when they won the Cricket World Cup in 2011 after a 28-year wait.
He could have continued as the coach, but he stepped down from the post to be closer to his family.
