Pakistan would face the toughest task against all the other contesting nations. It would provide the team an opportunity to try out new players and find a new combination. There have been debate after debacle at the Commonwealth Games whether to retain senior players who were blamed for poor showing at New Delhi last October and at Ipoh the seniors would have the best chances to end the debate. Pakistani seniors may have been wanting in physical fitness but if they are removed without getting a good replacement, Pakistan performance at international level would only suffer. The quality and level of hockey at international level has shot up so high that without a sprinkling of experienced physically fit seniors Pakistan could not dream of rising in international ranking.
