1.Want the core of the team same in every format:
Virat Kohli, Ajinkya Rahane, Rohit Sharma and Shikhar Dhawan are the core of the team in the T20 and ODI format. They have performed extremely well in those formats and the team has dominated almost every other team in the shorter formats. So there is absolutely no doubt that these players can excel as a unit in Tests too and so that can be another reason to retain the duo in the team.
