You're not taking into account that we have no creativity anymore thanks to an unnamed player getting arrested and Benitez ousting Rodriguez and Digne. Between those 3 last season they provided 28 goals and created 26 big chances.
For comparison Gray and Townsend have only provided 12 goals and 5 big chances.
If we'd some creative players in that squad yesterday we'd have won imo. The big thing for me was that most of the time it just looked like we couldn't score even when in and around their box.
