I generally don't want a drastic change in the team, but, unfortunately, Siddons carried dead weights in the team for too long, so some changes are inevitable.
Sir Ash: Simply sick of this moron, dump him, don't even let him be in the A-team. Lets try other options.
Riyad, Naeem: Both of them failed to adapt to their late order positions. It's high time Nasir be tried in place of Riyad and a specialist bowler replaces Naeem. Riyad and Naeem should be sent on the A-team tour as specialist batsmen instead.
SN: Looked real rusty in last two ODIs. The A-team looks more appropriate place for him at the moment.
This should be the series of reckoning for Rock, Mushfiq, and Zunaed. If they continue with their poor forms, and someone from the A-team put his hands up, they should be gone for good.
So, my playing XI would be -
I won't name a reserve bench for the series, I rather have fringe players sent on the A-team tour. If we so badly need an injury replacement, pick someone from the NCL. Use couple of good fielders from the academy to be used as substitute fielders and to carry towels.
