6. Ravindra Jadeja:

The left-handed all-rounder Ravindra Jadeja is another player, who is still unsure of his place in the side. He delivered for India with the ball by bowling economical spells and taking wickets at the crucial phases of the game.
Recently, Virat Kohli said that his inclusion in the side will bring a balance to the team. He can bat at the deep and bowl those crucial overs for his captain. To press his case further, he had a good record in England, where he bagged golden ball for his performance in ICC Champions Trophy 2013.
Again, it boils down to the question of whether India needs an extra spinner or not? He would be the obvious choice if India wants to get a backup for Yuzvendra Chahal and Kuldeep Yadav.
