There are several problematic things about that VAR descision:
- The time it took. There should be a time limit. 30 seconds and you can't spot an error? Well then the decision stands.
- The drawing of lines. Royal was in the air, the ball looked like it had already left his head, but who knows. Technology is simply not good enough for lines to have any real value in these tight situations.
- The over complication of the offside rule. I've always laughed at people who couldn't understand the offside rule. It's quite simple really, or used to be. Admittedly I don't know how the offside rule has been spelled out in the rule book in the past, but I refuse to believe that it used to allow refs to give offsides when the ball travelled backwards. Hell, even our players apparently didn't know this. It defies all logic and sense for everyone who are interested in football.
- Judging intent from TV footage. This brings a totally unneccesary subjective element to an offside decision. Basically this means refs make big decisions on their interpretation of body language. And what was the Sporting player's intent? You could argue that he intended to block the path of the ball from an opponent he thought he had behind him. Either way, his intent is impossible for the refs to make an informed decision about.
I've always felt the appeal of football has been its simplicity. Complex decision making processes and rules that are increasingly difficult to understand, takes away that appeal. It alienates fans and frustrates players. It's a very dangerous path to follow IMO.
