Chevalier then produced an amazing double save from Leon Bailey and Douglas Luiz, also denying Villa substitute Jhon Duran from close range in the final seconds of extra time.
In a frantic climax, Cash was also fortunate to escape being penalised for handball following a Var review.
Martinez, however, was not to be denied another famous night. Who knocked ‘Les Dogues’ out?
