Pakistan pace sensation Naseem Shah expressed his dissapointment about the defending champions' flimsy start in the Champions Trophy and emphasised the need to fix their mistakes before heading to Dubai for the blockbuster clash against arch-rival India on Sunday. Pakistan had to wait nearly three decades for a global tournament to return to Pakistan. But New Zealand spoiled the party for the co-hosts by handing them an imposing 60-run defeat in the tournament opener in Karachi. In a short tournament, where each team plays three group-stage matches, a defeat in the opener has jeopardised their chances of punching their way to the semi-finals.
