Playing with a B Team, can be a scenario, although there is an argument against this: if this B team gets beaten badly 4-0, then this might spread insecurity and distroy confidence among everyone, even those who did not play gets effected. (not everyone is so self-centered like Zlatan I.)
Giving key players rest is probably more important. I think EV might go a strategy in the middle. A mixed A/B team, resting everyone who is insure-prone... and losing 0-2 in the end. I hope I am wrong on this ...

Pique has already 3 yellow cards (lenglet 0) in CL,IDK maybe this will also play into the squad.
