They won't.
This game is not a missed chance for us to beat them, for them it was a missed chance for City to beat us. They will show all the goals but will then focus on the City misses and how good Haaland is.
If this doesn't show the board how badly we need a couple of new players nothing will. Not because we are shit but because we can be something amazing right now if we had that little extra quality in the squad.
No one will give a hoot about this game if we lose 3-4. But if we can get something that's an entirely different story and will be something to really build confidence.
