The idea that this contributed to the balls up is so silly. It was 2 days before and its a 6 hour flight. I mean imagine saying you couldn't concentrate at work cos you flew back from holiday 2 days before?
It was just a silly human balls up. It happens. The thing that can be learned from it is surely the framework can be changed to be able to pull back play when it's been established the correct call was miscommunicated.
The meltdown over this is absolutely bizarre.
