My personal view is that the fast-bowlers will wreak havoc against Zimbabwe so likes of Shaheen, Haris Rauf and Hasnain have a good chance but then Imad Wasim and Shadab could well be the ones getting most wickets.
It will be Shaheen. I don't want to sound arrogant. But my gut feel is that by the time Shadab comes onto bowl, their won't be many batsmen remaining if any.
