Time for Jadhav to be shown doors. A world champion team is the one in which everyone contributes. That's why England became world champion. India had Jadhav and a vacant no.4 spot which is why India didn't won the tournament. There is literally no place for players like Jadhav, Karthik and Vijay Shankar in the team.
I feel Mayank Agarwal should be given the opening slot as a replacement for Shikhar Dhawan. He is in good confidence and should do better than KL Rahul. Regarding Shivam Dube, I feel he can be handy for India at no.6 with the bat but his bowling is a part timer level. It was criminal to play him as a bowling all-rounder in this match. Unfortunately, India don't have any good option for the no.6 spot. Manish Pandey can be played in the team as no.12 man. That will be a huge boost for the side in terms of fielding. Jadeja should be persisted as well. He adds a lot of value to the team with his varied skills sets.
