LAHORE - PCB chairman Ijaz Butt has refused to comment on issues related to star batsman Mohammad Yousuf and said that legal aspects are involved in that and he won't talk on the issue. Talking to journalist on arrival from Abu Dhabi at the airport, he said that Yousuf did not call him before joining the Indian Cricket League and he can say nothing more on the issue. He also praised the team for their clean sweep of the West Indies. Meanwhile, new director of National Cricket Academy Aamer Sohail has termed the win a team effort. "All the players were supporting each other during the series, which is a healthy sign. The pressure would be on Shoaib Malik's team to maintain the fourth place in the world ranking. "Its now India's turn to visit Pakistan and support Pakistan by playing a here. But in case of emergency there should be no problem in holding the series on a neutral venue."
