Fantastic gesture, I don't see how you can spin the actions of the owner in to something negative on this.
Unfortunately, it seems likely that Portugal must be insisting on a high percentage, if not all attendees to the stadium must be in the official bubble.
Portugal have to make Covid decisions based on what they think is best for their country. It's shit for thousands of us fans, but I am sure they have their own legitimate reasons.
The same as our government has their reasons for not letting thousands of UEFA sponsors in without quarantine.
The villains of the piece are UEFA for me. They had the opportunity to move it to Wembley which would have been far better for the fans, but they've decided to put their sponsors first, which is a great shame.
