FA suspend England tickets over Tube strike
Now, this move is only a temporary one, because the FA want to allow "transport providers to ensure they can manage current ticket holders' journey to the stadium on the night of the game." Of course, a Tube strike could be a big problem for the match, with so many extra people wanting to get around London.
There's previous too - last year, Wembley's capacity was dropped for the game between England and Germany's women's teams, thanks to maintenance work, which ended up with a fair amount of mayhem with 10,000 people who bought tickets unable to get to the stadium.
The RMT union has set dates of September 8th and 10th for strikes, but of course, planned talks between Tube staff and bosses could be successful, and the strikes could be called off.
The strikes, of course, are all regarding pay and conditions for an all-night service. Even if talks are successful and everything runs as normal, if someone could see to it that the England brass band can't get to within 20 miles of the stadium, that'd be wonderful.
