Cook hails Ashes 'game-changers'

England captain Alastair Cook says the "game-changers" in his side were the key factor in England's 2015 Ashes series win over Australia.

Despite losing the fifth and final Test to Australia by an innings and 46 runs at The Oval, England completed a 3-2 series victory to regain the urn.

England's player of the series Joe Root says the team are "improving very quickly" and can be the best Test side in the world once again.
