I am really undecided about the level of corruption in PL football. I really do not think one specific team is favoured, e.g. Liverpool, but i am more uncertain about the 'protection of the product'. It would be quite naïve to simply dismiss the old adage - where there's money....there's corruption - just because it's the game we love and think it's some old gentlemen's game played in the name of sportsmanship for the love of it. So where does the truth lie? god knows.
My personal feeling is too lean towards that the league are constantly massaging the framework in which the game is played; the game laws, the financial rules and so on. Make it harder/easier for clubs to complete.
Do i subscribe to the situation that you describe, that refs are systematically or occasionally instructed to, for example, ignore pushing in the box on City players for a couple of games, and after that, for example, give the odd decent 50/50 decision in favour of a languishing United? I dunno. The thing is , every team is convinced VAR is against them, and every team can draw up a few decent cases. But then, you could argue that's the point, don't make it obvious!
I suppose it never ends. Really murky stuff though. I believe some things moving forward to improve officiating and team/fan trust are:
- Open up the VAR/ref communications
- Introduce much better on-pitch discipline rules from grass-roots upwards (players and coaches)
- Pay refs more
- stop the 'mates club' and get an independent review panel (for refs).
