England's next challenge to win abroad - Alastair Cook

England Test captain Alastair Cook says the next challenge facing his side is to play well away from home when they face Pakistan and South Africa later this year.

Cook admits England's 2015 Ashes victory over Australia "exceeded expectations" but believes some of the criticism levelled at himself and the team in the past 18 months has "not been fair".

England will hope to finish the series in style when the fifth and final Ashes Test begins at The Oval on Thursday, and Cook puts England's success down to his players making "big steps", from potential stars to proven match-winners, over the course of the series.
