Why is Virat Kohli favouring Rohit Sharma instead of Ajinkya Rahane?

India captain Virat Kohli said there is no need to panic after the second innings batting collapse at Newlands, expressing confidence that the batsmen have come out the 72-run defeat as more matured. He however did add that they would decide about the opening combination only after training, adding to the growing suspense over the possible team combination on Saturday.
