If I was picking an England team for the sub-continent, I'd go:
Sibley/Jennings
Crawley
Root
Stokes
Pope
Buttler
Foakes (wk)
Curran
Bess/Ali
Leach
Rashid/Parkinson/Virdi
Bat deep, 2 quicks and 3 spinners.
The last spinner spot is tricky, ideally you want spinners who all bring something different but none of England's leggies are playing red ball cricket. I suspect the group England will have to pick from will be Bess, Ali, Leach and Virdi.
Jennings has a reputation as a spin specialist but it would be harsh to drop Sibley who has struggled against spin already in his test career. The only way Sibley is going to learn is by playing.
Root, Stokes, Pope and Buttler are England's best players of spin so one or two of them are going to have to bat out a little out of position instead of keeping Burns in who struggles vs. spin. Dropping Burns lets you choose a specialist keeper too.
