Rizwan should play as a specialist batsman in every format - but that is to strengthen the batting.
Which means that the keeper should be Rohail Nazir.
In Test cricket:
Rizwan could bat in the Top Four and average 45.
Rohail could bat at Six and average 40.
1. Imam or Sharjeel or Abdullah Shafique
2. Mohammad Rizwan
3. Saud Shakeel
4. Babar Azam
5. Mohammad Nawaz
6. Rohail Nazir (wk)
7. Shadab Khan
8. Faheem Ashraf
9. Hasan Ali
10. Sajid Khan (Asia) / Naseem Shah (elsewhere)
11. Shaheen Shah Afridi
That’s a strong team for the 2021-23 World Test Championship cycle.
It bats down to number 9, and there are either:
4 quicks + 2 part-time spinners
3 quicks + 1 lead spinner + 2 part-time spinners.
