Raina and Kholi are more consistent player in their respective position than Pathan. And they both can play both aggressive and slow game as per the requirement.
Instead of Kohli getting dropped, the Indian Team can drop Gambir and promote Kohli at one down who has down very well at that position and include Raina in lower down the order. Than you have the option like if yusuf fails we can rely on Raina both of them can bowl as well and kohli and Raina are the best fielders in the team now compared to Gambir.
