People, both in the crowd and pundits on the TV, who know absolutely everything about everything, but especially about football, which is why they are sitting in the crowd/commentary booth, not being payed £60k/week like Moyes, despite the fact they know better.
"He raised his hands so he had to go". No, he doesn't, for violent conduct he has to go, but not for raising his hands, and they are not the same thing IMO.
Players appealing for every single decision no matter how obvious it is that they should get it. I can understand appealing for everything that might look like a penalty, its when the ball goes out for a throw in on the half way line and players from both teams throw their hands in the air appealing despite the fact everyone in the stadium can see which way it should go, but they appeal anyway, because they are all cheating bastards at heart.
Games not played on the weekend or a bank holiday. But especially those games that were scheduled for a weekend or bank holiday but then gets rescheduled (usually on Skys say so).
