Have you check out Hasan Ali performance in the last 15 ODI matches ? Please google it first before commenting next time.
What chance ? he has been regular team member in limited overs cricket for the last 3 years. In Champs Trop, most of the international players
doesn't knew new side of Pakistan that time for e.g these Fakhars, Hasan, Shadab etc ..so they didn't planned anything against them. With time, every player of that winning Champion trophy team has been tamed.
Apart from Babar Azam, none of these players have 'improved'. Good for PSL crap only.
