I read earlier that you've scored 9 offside goals overall this season, and if none had been allowed you'd be in the bottom half of the table.
I haven't personally seen all those goals so I can't 100% validate that, but I have seen 4 clear reds not given (2x Rojo and 2x Pogba) this season, which is pretty lucky too.
I'm not saying you haven't had any bad refereeing decisions of course, I'm sure you have, but I would be interested to see some analysis around how many points gained versus dropped due to refereeing mistakes in your matches.
2 red cards for Pogba?
Also, it is swings and roundabouts, maybe there have been more in our favour at the moment, but there has also been times we have had more against us. Probably in equal doses, so I am not going to complain about refereeing,. They are in and out of form just like any player.
The difficulty with creating stats and wins / losses based on refereeing decisions is that they are rarely in the last minute of a game and therefore there is more football to play. One decision doesn't mean you win or you don't. They might impact your chances, but not definitively.
A team might become disciplined and counter attacking after a red card and benefit from that, or the team may be spurred on, or even demotivated by an offside goal or disallowed goal.
Its a very narrow minded analysis. No other sport complains about the referee as much
