Cook seeks England improvement

England captain Alastair Cook says there must be "constant improvement" from his team if they are to achieve success as a one-day international side.

Cook's unbeaten 80 led England to a seven-wicket win over India in the second one-day international for a 1-0 lead in the five-match series.
