I am very excited about today's announcement on the ICC World Twenty20 2009. It has been officially confirmed that we will be playing in a joint event with the men next year, with the semis and final of the women's event taking place as a curtain-raiser to the men's event.
Normally I am glued to the action whenever Pakistan's men are playing in an international event, so to be part of the same event is going to be an incredible feeling. Urooj Mumtaz Pakistan women's team captain

So Pakistani women's team captain is the first to show interest. I think it won't be appropriate to watch men and women playing together. **What would happen after they get a wicket or win a match. **I am sure at least Mohammad Yousuf would like to keep his distance and not want to be congratulated.
