England skipper Joe Root has said that their victory in the seesawing first Test, despite being "not at our best", has energised the hosts with confidence as they prepare to take on India at Lord's tomorrow.

"It (the win at Birmingham) fills you with masses of confidence. One of the most exciting things about last week is that we weren't at our best, certainly areas we can improve, but we found a way to win under pressure, and wrestle momentum back in our favour," Root said at the pre-match press conference on the eve of the second Test.
