I would rest quite a few for this one, although I'm quite sure Frank will send out a strong team. We are already through to the knockout stages, and finishing first doesn't necessarily give us an easier opponent in the next round.
I would personally rest the likes of Silva, Chilwell, James, Mount, Kova, Ziyech, Werner. I also think CHO and Giroud desveres a start.

Azpi - Zouma - Rudiger - Emerson
Havertz - Jorginho - Gilmour
CHO - Giroud - Pulisic
