Totally agree. Which is basically how "umpire's call" works in cricket.It ought to be very simple: did the on field officials make a clear and obvious mistake in their original choice?
If the answer is uncertainty, then stick with the current decision.
If the decision is obviously wrong on first or second glance - 10 seconds max - then ask the referee to go to the pitch side monitor and make sure he agrees - then change the decision.
That would be the solution I would be happy with. But I have no faith that we will ever get there - and so I would rather go back to how it was before, with no VAR at all.
Otherwise we may as well not have referees in football and just let Mike Dean ref every game via a TV link.
Imagine how much he'd love that.....
