It's a completely flawed system. We have a situation now where nobody is allowed to ciriticise referee's, nor are they allowed to explain themselves, and yet the FA don't allow for there referee's to make mistakes/be human.
It would be easier if after a game, a referee could go through the game, say what they get right, and what they got wrong and they could issue out punishments/take away red and yellow cards based on that.
Yeah, but the other problem is you get these situations where the ref does see what happens, and seems to just decide to pretend they didn't see it. Like with Zlatan, or with Barkley earlier in the season in the Merseyside derby.
You also get situations, particularly involving Mike Dean, where the ref will invent something that never actually happened, which again is difficult to comprehend. I can understand a referee making a mistake by not seeing something, or not having the benefit of seeing it clearly...but when they see something that never happened and never looked like it did, that's difficult to understand.
Best example is Dean at the start of the season giving penalties for shirt pulling or obstruction from corners, when it wasn't actually happening. It was like he just decided before the game he would give a penalty for it, and guessed when it would happen. Dean in particular seems to just reinvent the rules as he goes along, often mid game.
It does come down to the system being flawed. There's no quality control at all, because no one can question a referee's decision. A referee isn't required to explain his decision to anyone. Yet players are freely allowed to hound them during the game. The easy option for the referee is therefore to just make whatever the easiest decision is at the time. They don't have to worry about the integrity of the decision, or whether it's accurate, because there's no consequence if it isn't. There isn't even any questioning. How often in literally any other sport do you not know why an official made a decision? It literally never happens. Only in football.
The whole point of having referees is to add integrity to the rules. If you don't even know which rules they're applying or when, why etc. then that integrity just isn't there. The system is so fecked it'd actually be fairer to just let everyone get on with it then referee retrospectively after each game.
