Var debate 2019/20

Let's be honest - VAR will reduce the ability of cnuts like Clattenberg to "go in with a gameplan" before the game has kicked off.

Just recall the City v Spurs game where he was 20/80 in their favour the entire game - then gave the dodgiest penalty I have ever seen live - then stood on the penalty spot legs spread both arms pointing at the goal for several seconds, I have NEVER seen any other referee do that in any game...ever.

We WILL get some dodgy VAR calls against us - but I think we will actually get more benefit, possibly more penalties and some of the tackles on our players in the last two years would have got red cards on review without a doubt.

Doesn't mean I like VAR, but if it gets rid of some of the shoddy decisions against us.....

HOWEVER -- their should be no special dispensation for clubs who cannot get their stadiums up to date and fit large screens - if the ground isn't fit for purpose it should mean those two are relegated.
 
Remember that that the linesman have been told to keep the flag down and let VAR decide if it was offside or not unless they are 100% sure it’s offside. We will have loads of goals ruled ut this year for this. Think how many times Jesus or Sterling have been flagged offside for goal scoring opportunities in the past that will now be left for VAR if it’s a goal. No point celebrating.
 
Interesting video from fifa about virtual offside lines. Independent testing of it. I looked it up to see how transparent they’d be re margin of error. Unfortunately they make no reference to that at all which is disappointing.



Then a really interesting thread in a refs forum
https://www.refchat.co.uk/threads/var-wobbly-lines.11773/

A comment caught my eye (quote below). A two in three chance that the tech can’t capture the moment the ball is kicked which is integral to the rest of the tech working.

So, on the tight calls, it is twice as likely than not that the call is wrong. Remember these are calls that are supposed to be objective and so no clear and obvious filter. Completely wrong.

Improving football?

“One more thing I am not satisfied with is the frame they check offside with. If correct technology is not used it could have a big impact on the correctness of the decision in tight calls. Basically if dedicated technology is not used, VAR decision can be just as inaccurate as an AR on tight calls because the frame used for the decision is not the exact moment offside should be decided but the closest frame available to it.

Bear with me for a bit of maths here if you want proof.

The standard camera/playback frame rate is 24 or 30 fps. At the better frame rate there is 1/30th of a second between the two frames that a VAR can look at the incident.

At elite level the top speed of footballers is about 40km/h. If an attacker is running towards the goal and the second last defender in the opposite direction to put him offside, its not uncommon to have a relative speed of more than 50km/h. This means the relative movement between the two frames (1/30 of second) is 46cm. This is a large gap. There is no way VAR can make a definitive decision based on that.

Another way of looking at it is the length of time the ball is in contact with a foot at a kick is just over 0.01 seconds (yes i did a bit of research for this). This means there is a two in three chance no frame actually catches any contact with the ball in a kick”

I see Jesus is offside again.

Interesting why dont they judge the ball when it just leaves the foot not contact? Like the early days of cricket reviews it will take time.
 
I'd doubt very much that the tech they're using is good enough to definitively call offside or not every time. If they admitted it, we'd probably be happier about it but they won't because the people who run and broadcast football have traditionally (historically?) chosen to insult people's intelligence, so they just claim it is without actually being able or willing to prove it.
 
All the players need to get a T shirt like Mario's with Why Always Us on it and pull up their shirts every time a goal goes to VAR.
 
I like it as long as every 0.00001m distance offside goals will be canceled that Liverpool is gonna score this season. This showed that Sterling was really maybe off by and inch of his shoulder.

I can accept that being removed as far as every single attack our rivals are off by same distance or bigger will be removed as well. If they are then they will feel the pressure.

Also the possibility of us never conceding an offside goals is great.

Lets wait and see until the real problems come up like faults that arent "yes or no" questions or handballs and stuff.

I am sure we will have moments especially with dangerours yellow-orange-red card tackles when VAR will be in the center or talk.
