The thing is, Leipzig's gameplan relies on them having space. Nearly everything they do relies on large spaces behind the opposition's defense for Werner, Sabitzer et al. to run into - including all the long passes from Upamecano et al.
We can deny them that space if necessary, and a low block will suit Mou just fine as far as things go. The key will be whether we include Aurier - his inclusion brings an element of chaos to the back line, but on the other hand, his recovery pace would be useful *if* we get caught out at the back.
I suspect there's a role for Dier tomorrow - at least, I hope so. My utter guess would be -
-----------------------Lloris---------------------
Aurier-------Toby-----------Sanchez-----Davies
-----------------------Dier-----------------------
--------------Lo Celso-------Winks--------------
Lucas----------------Alli---------------Bergwijn
Subs: Tanganga, Verts, Sessegnon, Skipp, Ndombele, Gedson, Lamela
I was deliberating between Winks and Ndombele - in the end, I don't really see a place for an attacking midfielder in that role given our massive problems up front now. Keep it tight first - Winks is marginally better for that than Ndombele seems to be, even if only because Ndombele's chronically unfit.
Our hopes now rest on Alli, for both the game against Leipzig and against Chelsea. The same low block will suffice for both, because both rely on their pace in behind quite a bit.
Alli needs to play like Alli, not like his damn brother. And if he isn't bursting into the box, if he isn't leading the line, if he isn't holding it up and playing it behind for Lucas and Bergwijn to run onto...we're essentially toothless.
