4. Rahul Chahar
Rahul Chahar has gradually picked the lessons on the go when it comes to the truncated version of the game. The 21-year-old leg spinner has often delivered the goods while plying his trade for five-time IPL champions, Mumbai Indians.
Having him as a back-up option will give the Indian captain an extra cushion. Moreover, he has already proved to be a smart bowler as he knows how to respond to pressure situations. Usually, Kohli would prefer Ravindra Jadeja and Washington Sundar.
At times, it is important to experiment or test the best strength to manage the workload of the players. This is where the rotational policy comes into play. Chahar took 30 wickets in 31 games at an impressive economy rate of 7.47.
