England captain Alastair Cook has challenged his side to end their frustrating inconsistency by winning two Tests in a row and regaining the Ashes at Trent Bridge. Cook's men took a 2-1 lead in the five-match series with a dominant eight-wicket win completed inside three days in the third Test at Edgbaston on Friday. Friday's victory came on the back of a 405-run defeat in the second Test at Lord's, which in turn followed England's 169-run success in the first Test in Cardiff.
