Even a blind man can see this was a foul.
Rugby Union is the perfect example of how VAR should work. The game is as fast as football and the interruptions are appreciated by the crowd who enjoy the spectacle and cheer the decisions. No one can argue with the out come as they are clear, obvious and honest.
I don't think the referees will be 'found out' per say as mentioned about. It's more a case that you have men in their 40s & 50s who are slower than the game is now played at. If you run your legs off chasing the pace of the prem at that age your heart rate is up, you are hyper ventilating and your decision making is impaired.
Much the the special forces training - they put their recruits through hell to see how the react under pressure when exhausted and fatigued. Having a ref in the stands providing a 2nd pair of eyes to the ref on the pitch is great support. It doesn't detract from the game or diminish the man on the pitches' authority rather it reinforces it as they players can't get away with the 'unsportsmanlike behaviour' - in other words cheating to us normal honest human beings.
Dives, time wasting, fouls, off the ball incidents etc would all be resolved quickly & yes each decision should be displayed on the big screens to show the crowd exactly what happened and why the decision was made. Also this would shame players into acting in a more gentlemanly manner - something which footballers are seldom accused of.
They brought in the shaving foam to mark 10 yrds for free kicks and it has been a great success. VAR done the right way will also improve the game, that I don't doubt.
What I would also like to see is pay-related-fines. If a player is on £200k a week then they should be fined £400k for cheating.
With punishments matching the players salary you would soon see a dramatic change in the way the game is played.
Will it happen? Not likely - Much like the criminality surrounding player Agents, fees, dodgy dealings etc. These issues won't go away but as more money is pumped into the sport as US media companies like Amazon Prime, Google's whatever & Netflix start to eye live sporting events these issues will simple be more exasperated than see any resolution.
Arron 'Sick note' Ramsey 400k a week - ridiculous - the lad isn't worth half a Waddles' Bo!!ok!
