That's the benefit of being at home. There's more of you to make a noise whenever you feel an injustice with the referee hopefully thinking "Well, if that many people all thought it was a foul/offside/handball/he's taking too long then maybe it is?"
Yep I completely get the point of the crowd getting into the refs mind, I was more talking about those that get apoplectic with rage that the opposition keeper walks to the other side of the 6yard box each goal kick. They’re not necessarily shouting at the ref just seething to themselves semi quietly then spending 10 minutes banging on about it, while lapping it up when our keeper does it. They’re going to do themselves in the poor lambs.
