It seems that you're starting to see the problem with VAR. Taking ages to make a decision : that's what VAR does. That's how VAR works, that's what VAR is. Yes, the longer the delay, the worse it is, because you are excruciatingly waiting for "permission" to celebrate or to breathe a sigh of relief. That waiting and waiting and waiting for a subjective decision doesn't work for the football fan. Sure, a 4 minute delay is more aggravating than a 3 minute delay which is more aggravating than a 2 minute delay. But by the time the decision is made, after any amount of time, the moment has gone. The moments that we live for as football fans is lost.
Now if we want to say "but it's more important to get the decisions right". There's no guarantee they're gonna get the decisions right by making us wait and wait and wait. But one thing we are guaranteed is the inability to be able celebrate in the moment organically. In many cases they take a perfectly good decision and turn it into the wrong decision, without any explanation whatsoever.
We can't let the fact that the decision went against a rival in Spurs stop us from being honest about the situation. The tribalism aspect to these decisions is what VAR feeds off of. Looking at the sequence, we know that was a perfectly good goal. The player who received the cross was clearly onside, the ball was kicked backwards, went off a defender forward. Now, Harry Kane was "about level" when the ball as it was kicked backwards. Part of his body was just in front of the defender, part of his body was in-line with the defender. There was no "daylight" now was there that we hear all the time about how offsides needs to be changed. Kane stayed "enough" onside for me, what what do I know? The ball was kicked back anyway. Imagine being offside by a backwards pass as you were pretty much level then deflected forward to you off the defender.
After something like this, I don't wanna hear anyone acting like offsides is black and white, that you're either on or you're off. No no no, offsides is often very subjective and subject to reinterpreted and changes "laws" many of which have been changed in order to accommodate VAR. Also you may have noticed in the slow mo replays that the defender even pushed Harry Kane. Kane didn't go down, and it probably wouldn't be enough to warrant a penalty in real-time, but if we're splitting hairs on endless super-slow mo replay, why couldn't that have been ruled a penalty on VAR. If you really want to split hairs here, if you wanna get technical, you could argue that Kane was actually pushed forward into an offsides position by the defender as he was fouled trying to stay onside. The point is, all this is wildly subjective.
That was not "clear and obvious" offside. You could watch that sequence and come up with a variety of subjective decisions, each of which someone would disagree with. But the fact is that the ball was hit backwards as Kane was "about level". And if you wanna say he was onside, he was being kept from being completely onside by being fouled forward by the defender. This VAR process is atrocious. That's a horrible goal-reversal. We may be happy about it as City fans but it's the wrong decision. It just is. We all know deep down that was a goal, and that beautiful moment for Spurs, as much as it pains us as City fans, absolutely should have stood. And it is highly farcical for that to be chalked off. It's an embarrassment for all footballers. VAR must be put out to pasture.
