Saqlain Mushtaq and Mushtaq Ahmed are very big name and it's hard to find such players. They had Saeed Ajmal for some time but he got banned by icc. I used to like Yasir Ali but yeah i agree lately he's being bit dodgy with his form.
Pakistan has fast bowling culture and i think that's a main reason they failed to create another Saqlain.
No doubt recently Pakistan have the biggest issue in spin department and no one doing anything for covering this because we have batting academies and fast bowling academies but after death of Legendary Abdul Qadir no one dare to have any academy for this purpose even PCB is also having no interest in this department which is surely big concern.
Saqlain Mushtaq and Mushtaq Ahmed both settled in England with doing jobs for different Cricket Boards because they have good offers and salaries but here in Pakistan no one giving them anything for doing this job recently we have Saqlain Mushtaq as Head Coach, but this is also not permanently it's going to series basis which is not good they need to do something better planning for this as well.
