Will Pant continue to open in Rahul's absence?
Also, Shreyas Iyer or Deepak Hooda? Ravindra Jadeja or Axar Patel? A look at the questions India face ahead of the T20I series
Pant had opened the batting along with Rohit in India's last two T20Is, scoring 1 and 26 in Nottingham and Birmingham respectively. India's original plan for the West Indies T20Is was to reunite Rahul with Rohit at the top, but Rahul is still recovering from Covid-19 and will miss the T20I leg of the tour as well.
Deepak Hooda's sprightly batting and part-time offspin could potentially help him jump ahead of Shreyas Iyer and slot into a middle order that includes Suryakumar Yadav, Hardik and Dinesh Karthik.
A fit-again Ravindra Jadeja is currently India's first-choice spin-bowling allrounder across formats, but Axar Patel has somewhat narrowed the gap between Jadeja and himself in white-ball cricket, with his heroics in the second ODI against West Indies. If India choose to manage Jadeja, who has been troubled by injuries in the recent past, Axar is a readymade like-for-like replacement.
In the absence of Chahal, Ravi Bishnoi, who is more of a wrong 'un specialist than a traditional legspinner, or a fit-again Kuldeep Yadav could get a look-in. During the T20Is at home against West Indies earlier this year, Bishnoi took three wickets in as many games at an economy rate of 6.33. As for Kuldeep, he showed signs of his best during his IPL stint with Delhi Capitals, dominating the league along with Chahal.
Avesh Khan or Arshdeep Singh? Avesh had leaked runs both in Nottingham and then in Port of Spain, on his ODI debut, earlier this week. If recent form is anything to go by, India might go with Arshdeep who had kicked off his T20I career with a maiden on his way to figures of 2 for 18 in Southampton last month.
