The thing is that once you start down the road of Var you can probably find reasons to disallow more and more goals, or give a penalty for multiple things every game, but this is not how it was sold, it was the clear and obvious mistakes, not .5MM offside by a nostril hair or the inconsequential touch penalty, or the ball blasted at a defender from close distance on to their arm. Technically these decisions might be correct and logically hard to refute but the impact on the nature of the sport is high, just takes a lot of the fun and spontaneity away and has us all bitching about the semantics of decisions.
Pre VAR, no-one thinks twice about Maguires involvement in that goal. How does football walk it back without causing greater issues?
