Ashes: Can’t afford to make any more mistakes, says Alastair Cook

England continued their preparations for the third Test against Australia in Perth - a match the tourists must not lose if they are to have any chance of retaining the Ashes. Alastair Cook will make his 150th Test appearance when the latest battle of the 2017-18 Ashes series gets underway at the WACA (Western Australian Cricket Association) on Thursday. But the former England captain will be under pressure in the third Test after failing to score more than 37 runs in his four innings on this tour to date. (Video courtesy: SNTV)
