The Aussies will explore the weakness in technique of the Paki openers like no one else has explored them before. With Yousuf one-down and Misbah at 2-down, Pakistan will be under pressure very soon once the openers go cheaply (which is most likely gonna be the case against Aussies).
I doubt Misbah should be given a chance to prove himself beyond this Kiwi tour, if he performs in last Test then he can be retained otherwise since Malik is not going anywhere then keep him for one-down and Yousuf 2-down. Though as much as Younis is good in Test his drama-queen stints make me think that we should keep him away otherwise we will have more and more drama-queens pop up in the team.
