England still desperate to improve - Alastair Cook

England skipper Alastair Cook admits his side are still "desperate" to improve after they clinch the one-day series against India.

England were held to a draw at a rain-soaked Lord's, but Cook says it was a "fair result".

The skipper also praises the "outstanding" Ravi Bopara after he scored a brilliant 96, saying that the Essex batsman will continue to grow in confidence after this performance.
