My line up:
----------------------------Ederson------------------------------------
Walker------Otamendi------------Mangala---------------Danilo
----------------------------Yaya--------------------------------------
----------------Gundogan---------Bernardo---------------------------
Foden---------------------Aguero-----------------------Sane
Still a very strong team for me that should comfortably beat Feyenoord.
I would start Foden at RW, if I'm not mistaken this is the position he has played at the u17 World Cup and where he scored from in the final. Bernardo gets only his second start in the position he was bought for (West Brom in the cup the 1st).
Would have De bruyne on the bench and bring him on only in case we are still drawing in the second half. Otherwise bring on Jesus for Aguero, Diaz for Sane and then Tosin for Walker (Mangala to LB, Danilo to RB).
The only weak points here are Yaya who has looked unfit and not up to it lately and Danilo at LB who offers almost nothing going forward from the left side.
From Tuesday until Sunday is enough rest
