I don't think there was a single thing that they were saying would be enforced which actually happened. No ID checks, no one enforcing mask wearing or social distancing, no one caring about what time you turned up at and even letting you in the outer gates at whichever one you turned up at.
Not sure why UEFA didn't just punt the unsold 2.5k tickets to anyone who wanted one. This messing about with only offering to people who lost out in the ballot has just cost them the cost of the unsold tickets for no real reason.
