I don't have any problem with Vihari but i doubt if Virat is ready to leave his deputy atm and if we look at the last 2 years numbers Rahane looked better batman when comparing to Kohli.

Both Rahane and Kohli have been out of form for sometime. The difference is that Kohli can't be dropped even if he scores 0 runs in the next 5 matches, while Rahane may get dropped after this series if his form doesn't improve. But one thing we need to remember is that Rahane and Pujara are the two test-specific batsmen in the Indian squad currently. Everyone else is better in the shorter format compared to test.
Rahane averages 38.85 for 2020, and 21.05 so far in 2021. But he had a test average of 71.33 in 2019 (642 runs from 8 matches). Compared to him, Kohli's record is worse. Average of 19.33 in 2020, and 27.15 in 2021. But in 2019, he had scored @ 68.00 (612 runs from 8 matches).
I don't think even Rahane can be removed from the team, we really don't have many options in place of Rahane with us, the only appropriate backup is Hanuma Vihari which too has not been in great form when last tried, they won't bring Mayank Aggarwal, so obviously there aren't a lot of options available, I think India will pick up the other method by creating batting depth using all-rounders, I think one pacer will be dropped in the next match and an all-rounder like Sharadul could come in, on the batting side, even Ravindra Jadeja might be dropped and Ashwin could come into the team.
