I agree that it is looking really difficult to include Morgan as there is too much talent - and with Morgan not on the best form then it is a tough choice!
I also agree with a comment made earlier that Morgan can be a match winner if he hits form. But I am 99% sure that Morgan will be in the starting XI - so my team would have to be:
Hales
Roy
Root
Billings
Buttler (W)
Stokes
Morgan (C)
Ali
Rashid
Willey
Plunkett /Ball
If Morgan has to be there, then I think that you cannot put him above Billings, Root or Buttler - especially on current form.
Therefore bat him at either 6 or 7 where there is slightly less pressure and he can still Captain from?
We need Stokes (as all rounder) and 2 other seamers. And if Morgan has to play then for me it is Dawson to miss out! Dawson looked good with the bat but his bowling obviously wasn't great.
You need to play your better spinners regardless - and that was Rashid and Ali. But nothing to stop Root having a bowl if the wicket spins, as he has a real knack for taking wickets!!
