So currently, the candidates for Pakistan Test Openers are:
1. Abid Ali
2. Abdullah Shafique
3. Imam Ul-Haq
4. Imran Butt
5. Azhar Ali (to move from 3 to opener)
6. Usman Salahuddin
I'm not a fan of Abid Ali at all and even though Abid Ali is a minnow Basher, end of the day, he is capable of bashing someone, while most of these openers, and even Babar can't do that. Abid Ali is currently one of our best options for opening batsman, even though I myself don't like this. Credit to him for his century and 91 against Bangladesh that helped Pakistan stay and win the game.
As for the other options, Imam Ul-Haq is currently quite Poor in Test Cricket, Needs to play more First Class matches. I believe Imam Ul-Haq is one of the best options for Test opener and has the potential. Azhar Ali should retire, he is finished. Imran Butt, as we all saw wasn't good enough also, however, he still can make a comeback. Some are talking about how he should be on the team simply because of his great slip catching, and yes even though his slip catching is brilliant, his job is to be an opening batsman. but to be honest, I highly doubt he will be good enough to be a permanent option.
Abdullah Shafique should not have even made a debut, since he as played only 3 first class matches. But now that Abdullah Shafique has performed with his two fifties, he will be overhyped a lot, and I expect that he will be favoured now. Problem is he will probably get exposed against better teams, and everyone will start complaining about how he doesn't have enough FC experience... Same situation with Naseem Shah and Muhammad Musa Khan.
As for Usman Salahuddin, I feel for him, as he keeps getting ignored, and I feel like he is going to keep being ignored, otherwise they should definitely try him at opener and 3. Anyone know if he has been performing as an opener in domestic? Regardless, he definitely should be selected for Pakistan Shaheens at least.
So for the next couple of months at least, the opening combination will probably be Abid Ali and Abdullah Shafique. This is the short-term combination. In the long-term and future, the following have the potential:
1. Abdullah Shafique
2. Imam Ul-Haq
3. Omair Bin Yousuf
Let me know if I missed anyone else
