Sadly, Shan Masood is out of contention.

Sarfaraz has suggested that Azhar will be back at the top of the order after a short stint back at #3 so that's one slot that's taken.

It's between Sami/Imam/Fakhar.

I'll go with Imam but it'll be harsh on him to debut in England against Jimmy and Broad, hopefully he has the strength of character (and technique :asad) to thrive.
