City's disallowed goal

How do you know this tho?

It’s been quite widely discussed in response to yesterday that they don’t have a camera on the ball to show the moment when the ball leaves the foot. So the timing is imprecise and the lines drawn from the active body part are done manually - so there are a few pieces of judgement that are at play when making the offside call. 

 

I think it it would be good for them to do something like they do in cricket where if the technology shows it to only just be hitting the stumps (I think it’s half of the ball) then they go with the umpires original decision.

I think this is missing the point that the technology can’t be used to accurately rule offside to within a Cm or an inch - if it could then fine, but the ‘offside’ picture that is floating round is clearly spuriously accurate. To me they’re level and you give the benefit of doubt to the attacking player in that situation, their goal should have stood imo.

 

To you they’re level, but not to the technology that can pinpoint where the players actually are.

 

I’m not saying it’s perfect but it’s a hell of a lot more accurate than a linesman trying to focus on two places at exactly the same moment.

See my post above, I’m not sure anyone is actually claiming that the technology can pinpoint this yet. If it could then no issues, if it can’t then it’s a bit silly to let it rule on such tight calls like this one.

 

Don’t get me wrong, I’m in favour of the technology and VAR as an idea. I just think the implementation could be improved.

not come across anywhere that explains how the actual image is arrived at.

But i think the're some misconceptions about the lack of accuracy being taken as gospel.

There are cameras that work at up to 2500 frames per second, whether this high  a rate is used, I don't  know , but the oft quoted 60 fps quoted by posters is surely too low.

As for the "where do they draw the line" often asked, the  easy answer is, they don't. The software will be drawing the line based on(at a guess) the colour intensity of an individual pixel.

As to when the ball is kicked, that will be easy for the computer as the ball velocity will be measured, again using a pixel count.

 

I am only guessing at this, but even if the techniques are more advanced than I can think of, it will be along similiar lines.

 

Maybe an idea b to join a professional camera/video  forum, could get an expert insight.

I suppose that my gripe really is the time taken, when a decision is that tight, and we are talking mm here, I think the rules need to changer to give the attacker the benefit of the doubt. That would speed things and we would all know where we stand. No system is perfect but it is what it is and nothing can change now at least until next season, or there would be outcry at the marginal decision taken so far.

 

I was not aware that the clear and obvious criteria did not apply to offside decisions but that now explains a lot. Until such time as the rules on what is and is not offside are changed we have to live with it. Personally I would like the criteria to be based on where the players feet are, or at lest enough separation to determine a clear advantage (although this will still be somewhat subjective).

Someone made a good point earlier when they mentioned that the body shape of a defender running out, compared to that of an attacker running in the opposite direction will always favour the defender in this situation as you tend to lean into the direction you are running, This can easily result in the attackers feet being behind the defenders yet their upper torso/head beyond the back of the defender, and hence offside when the lines are drawn.

Yes Son was hard to do in my opinion but despite the outcry, over a season these will pretty much balance out, hence why nothing can be changed until next season.

Surely that has potential to cause just as many stoppages? 

Cricket is a stop start game as it is, football isn't. 

 

If we have the tech to make consistent decisions, why not utilise it rather than have it there but never use it?

Yeah I understand what you’re saying, but at the moment while it clearly isn’t perfect, they still have to go with what the technology offers. 

 

A linesman making a call on that has to use a certain degree of guesswork. It was a very fine margin but VAR showed enough for them to make a call. 

 

I wouldn’t have complain had the goal stood and the VAR stills were milliseconds behind.

I'm amazed our decision went to VAR.  What the heck was the linesman doing? Clear offside.  Officials are becoming complacent, thinking technology can dig them out of a hole.  

 

Well, in this case, it did.  lol

 

I think they have been instructed to let more things go, knowing that VAR will get it right. If they incorrectly flag and play stops before a goal that can’t be undone. 

 

In the future we’ll be teaching kids, play until the ball is out of bounds rather than play to the whistle.

When the ball rebounds back to him he can`t be offside?

He was offside when the ball was kicked... ergo he's offside when it rebounds back to him. 

 

This has been in place for like a couple of decades now, I'm not sure how people are having an issue with this.

Let’s think how that would’ve worked for the match on Saturday. Spurs would have challenged our first two goals. We would have challenged Spurs first two goals.

 

That’s two more VAR stoppage than we actually got then.

It’s a damn sight more accurate than some schlepper on the side line waving a flag. Based on the technology we have at the moment he was OFFSIDE. Everyone is assessed using this technology so it’s consistent.

I'm now more content to believe that it will even itself out over a season using VAR. Although 'evening itself out' was often used pre VAR it was difficult to believe given that it was clear that certain clubs usually got tight calls in their favour eg. Those plying in red at Old Trafford or Anfield.

City fans should be rejoicing about the use of var, how many result changing decisions have Arsenal incorrectly been on the right side  of against us, since we came up?

Liverpool pen that should never been?

Big sides have always been favoured, this  nearly levels the chances.

You realise that’s no different to saying everyone is assessed with the guy on the sideline waving a flag so it’s consistent?

What about the report last week that showed VAR could be as much as 14cms out? That margin of error could have put Son onside.

And both disallowed 'goals' were initially given!

It is, it is a consistent approach everyone is judged by the same criteria with the same slightly inaccurate frame rate. Rather than each game having a different flawed human being on the sidelines with their own experience and interpretation which suffer from fatigue in different ways.
