DUBAI (AFP) - Pakistan manager Naushad Ali on Sunday praised captain Misbah-ul Haq, saying his leadership qualities are key to the team's progress after a turbulent last year marred by a spot-fixing scandal in England. Misbah led Pakistan to a comfortable nine-wicket win over Sri Lanka in the second Test here on Saturday, taking a 1-0 lead in the three-match series. The first Test in Abu Dhabi ended in a draw. Since taking over as Test captain in the post spot-fixing scandal Misbah has not lost any series with Pakistan winning four of nine Tests, losing one and drawing the other four. Misbah, 37, will also lead Pakistan in one-day and Twenty20 versions of the game after Shahid Afridi was sacked in May this year. Ali, a former wicket-keeper batsman, said Misbah is key their success. "Misbah is a wise captain and his best quality is that he is cool," said Ali.
