Gill should go one down as he does in tests and Jaiswal should open with Rohit. Guy has been consistent performer and It would be disadvantageous for the team if he stays out.
Also, I guess they would do experiments in ODI series against England since squad is same as CT (minus Harshit Rana) and figure out the playing XI there.
Also, it looks like Virat has confirmed his participation in Ranji.
