The latter. Go on any forum, talk to any fan of any club, and you’ll hear the exact same thing as youre reading in here. Every single club and its fans believe they’re picked on.
The truth is the game is run by refs who are human beings. Human beings fuck up in whatever profession they’re in. In football, unfortunately for them, their fuck ups are highlighted, talked about and accusations thrown at them.
The single truth though is they’re just errors, with fans then claiming bias, conspiracy or whatever.
Good old football. Wouldn’t change it for the world.
