It's all about the attitude, says Kohli after India's victory
Indian captain Virat Kohli praised the side's attitude post the win.
"It's all about the attitude. If fast bowlers are going to think that spinners are going to do all the work, then it doesn't justify their place. They ask for shorter spells so they can give 100%. It's all about wanting to play for the team even in conditions that are difficult."
