Oh, and as this has turned into a general referee complaint thread...
One aspect that annoys the hell out of me is when referees clearly don't understand how to use the advantage rule. To give a couple of examples:
1. In the Burnley game there was a moment where Robertson was fouled probably 10 yards from the corner flag after he had played the ball back to Gini. The referee waved play on because we still had the ball, but Gini was immediately closed down by a Burnley player and so just had to play the ball backwards to one of the CBs or Thiago. So now instead of having a free kick in a dangerous area that is equivalent to a corner, we instead have harmless possession and Burnley can reset their shape.
2. In the Utd game Gini received the ball under pressure midway in his own half and shielded it really well, which caused the Utd player (Pogba?) to drag him backwards and obviously foul him. Again the referee sees the foul and allows play to go on because Gini still has the ball. But now he is being closed down by two players and so has to play the ball back to one of the CBs who is immediately closed down and has to knock it long and give away possession. So instead of having a free kick that allows us to reset and move up the pitch and have some controlled possession, Utd have the ball back.
These happen all of the time and yet would never be counted as mistakes in any metrics. There are lots of other issues like that which won't show up in any metrics, such as:
- not booking a player for a foul and then booking someone 5 minutes later for an almost identical offence
- booking someone based on the mythical 'totting up' process but not booking someone who has actually committed more fouls in the same game
- not giving someone a second yellow card despite it being a clear booking if he hadn't already been booked
- not booking a goalkeeper until the 85th minute for time wasting despite them taking 30 seconds over every goal kick from minute one of the game (hello Nick Pope)
- (my personal favourite) giving a free-kick the second that a defender gets touched and goes to ground, but never giving a free kick to an attacker in the same situation
None of these are 'mistakes', but all of them impact the game massively.
