Then, do it under some policy and explain that - like age, future plan, fitness..... You can't pick Wahab and ignore Irfan after the SRL Series and National T20.
I am the one here posting many times regarding reduction of average age of the squad, but honestly can't fault the selection if they had picked Wahab and if they had made Azhar Test Captain.
Ahmed & Umar were called back - they failed and got dropped. Team got blanked by SRL reserves, Irfan performed in next domestic tournament, got called back - I don't see much fault here. Yes, if he is persisted with next series or there after, after a horrible AUS tour, I can understand.
You see, the problem is when team isn't performing and expectation is beyond the level of the team - selectors can never win. You pick Faheem here and he won't have uprooted any tree in AUS - people would have said that Misbah picks PSL performers blindly, regardless of domestics. Now, the best performer of domestics is picked (with additional attribute of height for AUS Tour) - people are still un happy.
The problem isn't selection, trust me - problem is in expectations, that on "Talent" level PAK can compete with full AUS side in AUS, be in T20 - even today, I was silently reading that 150 could make AUS struggle...... Get over that, I don't think Irfan was a poor choice - he still can give top 4 overs in T20 which will win games against mediocre sides or had AUS rested 6-7 of their starters - something I am not confident about other options left.
