... but you can't make the problem go away.I think the problem here is the VAR protocol. Many people have looked at the incident and thought that the decision was clearly and obviously wrong whereas others (including the VAR) have looked at it and thought 'I see nothing clearly and obviously wrong with that'.
The problem is that "clear and obvious error" is so poorly defined that nobody knows where the threshold is. Last season, referees used a lower threshold despite the protocol being worded exactly as it is this season. UEFA seems to use an entirely different threshold. This will continue to happen until the "clear and obvious error" threshold is replaced with something else.
Redefine 'clear and obvious' or use different words and you just create a different arbitrary line with arguments about what is either side of it.
The only way of solving it is to go with simple right or wrong, but we know many decisions in football are subjective so you are just substituting one person's opinion for another - whether that is better or (I would argue) worse, it still doesn't solve the problem.
As long as you have VAR intervening on subjective calls you have this problem.
