I think there has been a spate of questionable decisions this weekend, and many have gone against us and in favour of our direct challengers (and United). Hence a bit of a revival of this thread.
But taking off the blue tints, the United goal was probably ok. Liverpool only had to see out a few minutes and probably would have won anyway. And the De Bruyne penalty decision was arguably correct also. We can't really say the resultant points awarded were affected much, if at all.
When was the last time we had this many contentious decisions in one weekend? Or when we felt we had been treated unfairly by VAR? There havn't been occasions many this season, and this is suggestive to me that things are improving.
There are still some questions I would like answered though, such as why a Match Commander is needed, and what are his actual powers.
Not perfect, but I can see improvements.
