The notion that referees are not human beings, and swayed by emotion, is ridiculous. Pressure does funny things to people, and it manifests itself in lots of ways. I do not believe that there is a conspiracy in favour of big clubs. I do believe that human beings find it harder to make decisions that are likely to be less well received. I do not believe that VAR is doing any sort of job of correcting emotional decisions.
There have been plenty of occasions where manure have committed offences in their penalty area, and not had the correct decisions awarded against them. That's just a fact. It undoubtedly happens, on average (to a greater or lesser extent), in favour of all home clubs. Human beings don't like tens of thousands of people being vile towards them. So they have a tendency to be over sure...and that sways the percentages. It is amplified when there are other factors likely to be at play as a result of size of club...and of course passages of play, and where they occur play a part of that. That nailed on penalty for wolves last night wasn't not given because Manure were in the wolves penalty area more.
