Ideally I would drop Rana for Asif but should Pakistan rest 17-year old Mohammad Aamer against Australia to prevent burn-out? He has been bowling non-stop since T-20. Inzi for instance overbowled Asif during his initial games and the excessive workload finally took it's toll on Asif resulting in him having fitness issues
Plus Aamer is single pasli. I am sure with age his pace and muscle mass will increase
Must use our premier bowlers with care
