As KL Rahul has undergone surgery for appendicitis recently, and his travel to England for India's Test tour being uncertain, the focus on opening options shifts to the team's reserves.
The Virat Kohli-led team includes four batsmen who can be used to face the new ball, including Rahul. While Shubman Gill and Rohit Sharma are likely to start in the playing XI as openers following their decent individual performances in Australia (and also the opening stands of 70, 71, 11 and 18), questions are being raised over the bench strength in case any one of the two batsmen fail.
Apart from Rohit and Gill, the Indian team comprise Mayank Agarwal, who suffered a torrid time in Australia as opener (scores of 17, 9, 0, 5) and Rahul hasn't played a Test since August-September 2019.
