The loss was frustrating, but any conclusion more negative than that is unreasonable. We're beyond the point of counting moral victories, but we very well could have won had we converted our several chances, and we'd be top of the group.
The actual concerning point from tonight is the bloated injuries list - Botman, Isak, Murphy, Tonali (ban), Barnes (have I missed anyone?)... If Bruno picks up a yellow against Wolves I reckon I might get some time on the pitch against the Gunners.
