English captain Joe Root admitted to committing tactical blunders and said he underestimated the Indian lower-order after Mohammed Shami and Jasprit Bumrah’s batting heroics fashioned an epic win at Lord’s in the second Test.

England were in a dominant position before they lost control during a chaotic unbroken ninth-wicket stand of 89 between Shami (56 not out) and Bumrah (34 not out) on the final morning at Lord’s.
