I think the team we saw today is going to be fully rested for United:
----------------------------Steffen-----------------
Walker/Cancelo--------Ake-------Laporte--------Bernabe
----------------------Dinho---------Zinchenko
------------Bernardo-------------------------Foden
---------------------Delap-----------Ferran
Continuing the 442 (4222) Set-up we have been using
Academy Subs: THB, Doyle, Palmer
Ake and Laporte should both play, yes they are both left-footed, but clearly Dias playing LCB so well and other top players in the world doing this show it's really not a big deal, so I think Ake could do it, or swap with Laporte.
I'd stop with this Zinchenko LB experiment and if we are playing with 2 DMs, then that's a great position for him, he and Dinho can partner there. Bernabe will provide width on the left.
The front 4 picks itself, with Delap as the "main striker" and Ferran playing off him. The 3 academy subs should come on as well at some point.
I'm still not sure if Walker or Cancelo starts against United, probably Walker for his pace, but Cancelo is more of an offensive threat, so not sure.
