Agreed, Fakhar was very good at #4 last series.Even with Azam available, it would be better to have Fakhar at no. 5 and use him as a finisher.
He hasn't done well as opener in T20's, but too good to leave out and best to use his hitting abilities down the order at 5.
Top 4 should be:
Saim
Babar
Usman/Fakhar
Fakhar/Usman
Although I’m sure there’s some concern with how bad he looked in the recent PSL.
