Only openers' spots are permanent: Gautam Gambhir

India head coach Gautam Gambhir has said only openers have permanent batting positions in T20 cricket, while the rest of the order should remain flexible. Gambhir made the remark while defending Shivam Dube's promotion to number four ahead of captain Shreyas Iyer in the second T20I against West Indies. Dube scored 7(10) as India lost the match despite posting 249/5.
