Former-England-skipper Michael Vaughan once again brought forth India's middle-order woes, saying Men in Blue lack-power in the engine. India's weak middle-order was exposed during the 3-match-series opener against Australia as the hosts faced a batting collapse in Mumbai after the dismissal of the top-order. Vaughan took to Twitter to say that India have underachieved in the last 2 World-Cups where they made semi-final exits.
