I would risk it and play KWP at RB.
So no Davies or Rose at today's training. Jan at left back?
I pray Rose and Aurier are both fit
How Dortmund work tactically:
We're up against some real pace - so I pray Rose and Aurier are both fit and up to the job - and I know this won't be popular, but I'd start Sanchez and leave Toby on the bench.
I'd put Jan on the left and Sissoko on the right. Although Sissoko and Aurier are a better combo than Sissoko and Trippier.
I'd never be surprised to see Aurier missing tomorrow. It's his missus's turn to be on the front section of the newspapers after facing trial for "sextortion" back in US. See Aurier thread :-)
How Dortmund work tactically:
It's a very good read and Poch will have to really have us on song to break their rhythm of play, especially how they use the false 9 - as the article correctly points out, how Liverpool do and had so much success with it.

As you know Ex we're up against a top side who'll be asking a lot of questions to our defence, we need every edge we can get out on the pitch. Our pace & experience need to be working together.
