I would have loved to see Sharif bowl as soon as possible - but in that case, we have to sacrifice 1 pace bowler, possibly in either Tareq Aziz or Mushfiqur Rahman in the final eleven.
I'm sure Mushfique won't be dropped, due to his affair with Whatmore,
as well as his batting capabilities, so the only other choice is getting Sharif in place of Tareq Aziz. Then again, we may end up making a turning pitch where we won't need more than 2 medium pacers in Tapash and Mushfique.
There is also Tareq Aziz's batting capabilities. His batting contributions helped in drawing the test match in the WI for us.
