Based on how Poch rotates goalkeepers for the cups, rotates fullbacks in general (where possible) and the fact that Aurier will have been able to train properly with the group then I can see this being our lineup:
[formation=343, Vorm, Toby, Sanchez, Vertonghen, Aurier, Dier, Dembele, Davies, Son, Kane, Eriksen][/formation]
Perhaps there's a chance that he'll want to avoid Dier burning out (especially with Wanyama injured) and so may play Winks or Sissoko there instead.
Any more rotation than that would be careless against Dortmund, in my opinion (I don't want to think about the last time we did that).
