LAHORE Former Pakistan captain Imran Khan has been impressed with the progress of the Australian team in the ongoing World Twenty20. They came into the ongoing Twenty20 World Cup in the West Indies unseeded but Australias success in the tournament has caught the imagination of former Pakistan captain Imran Khan. Imran feels after losing some key players in the past couple of years, Australia played the waiting game to get accustomed to crickets newest format. I think Australia is a perfect example of how to play T20 cricket like a science, he said. They (Australia) lost some great players and took time to recover. Initially they didnt do well in T20 cricket but now they have come to terms with this form of the sport as well, Imran said on a television show. The Michael Clarke-led Australia produced a clinical performance in all their matches so far to storm into the semi-finals of the Twenty20 World Cup, where they will take on defending champions Pakistan.
