Careful, you are treading close to logic/reason here
Nuno obviously feels the squad/first 11 isn't fit/ready to put in big shifts back to back. There is zero chance picking that squad he didn't (before the game) accept a 0-0/0-1 or even 0-2 result could happen.
Win the game against wolves, 6 points on the board, probably supplement this team slightly for 2nd leg, take care of business.
From the game itself, we were just too slow tempo wise, nothing we didn't know -> Doherty, Winks, CCV not up to level against any opposition, Romero, Gil, Lo Celso, Sessegnon all need game time (one of the reasons this competition is relevant). Opposition really had one chance, it happens ..
I really can't understand why CCV is still here, all he does is play a few pre season friendlies then gets shipped out on loan then repeats again next year. It's about time we shipped him out, he's never going to make it for us.
