I renewed my two tickets today and asked the young man in the office if he had any more information about what is going to happen. He confirmed that the season will start behind closed doors initially and that they are waiting on the government as to what will happen in October.
He said there might well be a ballot and I asked if this would handle pairs of seats such as mine. He said that this has not yet been decided but that it might possibly go by purchase orders.
Refunds for any matches you are not allowed to go to, of course.
