Arsenal are mentally weak and naive - they lost the plot as always at Old Trafford

Arsenal have started hitting Manchester United again. VAR had quite the weekend. And Liverpool fans realize it could be a little worse.

In a terrestrial VAR, away from the VARDo you know what the VAR is?

It's the equivalent of when you're on a subway or a bus, happily having a good time and then, shockingly, you're held up at a station or stop, inexplicably, for three or four minutes.

Because someone in the managerial class staring at a screen feels they have to justify their own existence by "equalizing service".

People in the field are doing great, but head office needs to show who's boss.

It's VAR.By Bob Crowe, Millwall, Heaven

So why was VAR used and then not used for a foul?

Arsenal fly-half sent off after VAR intervention. I may not agree, but I can at least understand it.

So in the 24th minute, when Saka is fouled and his back leg is taken by Martinez and the referee does nothing, why didn't VAR call him back? A clear and obvious error is what it is meant to be used for.

What is it for? JT

Why do we keep getting these ridiculous errors even after the introduction of VAR?

Why don't you listen to professionals who can help you?

They played the game and totally understand – more than bloody fools who control everything behind the scenesPhilip

West Ham's call was ok Probably won't change my mind much with this, but nothing is right. This is my take on Cornet's excluded lens and I'm obviously biased, so feel free to ignore this if it's an issue for you.

It was clearly a foul on Mendy and the referee was absolutely right to rule out the goal. When you see the part of the incident that the referee used to make his decision, there is clear contact between Bowen's back leg and Mendy's shoulder. Did Mendy overdo the contact? Yes, 100%. The referee did not even consider this because despite all the play he gave the goal at the start.

An interesting thought experiment is whether Mendy missed the ball and knocked Bowen down. It would have been a stone penalty because he made contact and didn't win the ball.

West Ham should be more unhappy with the decision not to fire Reece James. I like this guy to pieces, but he clearly kicked Antonio and should have received another censure. Nikhil N, CFC

Double standardsI watch Alan Shearer rant over and over about refereeing/VAR errors in Saturday's matches during Match of the Day.

“Shocking, abysmal, disgraceful, (beyond) terrible” were some of his thoughts on decisions and how they cost teams points, how “hard working” players are let down and how those decisions cost to managers their jobs.

After the Newcastle game, Danny Murphy supports him and goes further to say that Eddy Howe should have been more forceful in his complaints to 'put the referees on alert' in the next game. Similar sentiments seemed to be shared by just about every other pundit, including Jamie O'Hara on Sky Sports News, when discussing Saturday's matches. So a clear message that when officials make a mistake, they are i) completely out of order, and ii) fair game for vitriol.

Compare that to comments from Match of the Day pundits on some bad mistakes made by players - Che Adams going a full ball from a header and being penalized for "scoring" with his arm is laughed at, Maxwell Cornet misses a the open goal (face against the post) was not mentioned in the post-match analysis and various other unforced errors made by players who are paid much, much more than the officials were ignored.

So the official makes a mistake - carry on. A well-paid player makes a mistake - that's football.

I'm not saying mistakes made by officials aren't a problem, although these seemingly "terrible" decisions are rarely as clear cut as some might think. However, pundits should have a professional responsibility not to lead the pile of officials, especially when they are never so critical of the players.

It is becoming increasingly difficult to get people to become referees in amateur football due to the level of abuse they experience; scapegoating officials by experts (and managers) will continue to aggravate this situation.Paul, Cambridge
