Don't be daft. Making an exasperated noise, fair enough. But I think many rightly have an issue with someone standing up and screaming obscenities at their own players for the crime of not being good enough at football. How exactly does that help the team? It doesn't. It's counter productive...
People seem to confuse "not scoring" with "playing bad". They are two completely separate things.
The first half yesterday was VERY GOOD. We played with a lot of attacking intent and bombarded their box. The finishing wasn't great but the build up play was very good.
