Pakistan off-spinner Saeed Ajmal took a career-best seven wicket haul to destroy England's much vaunted batting line-up on the opening day of the first Test here on Tuesday.

The 34-year-old, whose claims of a mystery delivery surrounded the lead-up to the three-Test series, had figures of 7-55 which wrecked England to 192 all out on a slow turning pitch at the Dubai Stadium.
