Turns out it was the best thing that could have happened to AZ. They go to the locker room and refuse to return to the pitch while they are losing 1-0 and now the red card is rescinded and are rewarded with a complete replay from scratch with no crowd. Touché Verbeek. You gambled and you won.
I can see that this is a very sensitive issue for you. It is for me as well. But I'm not going to debate you on the finer points of running security in a 50k capacity stadium in a picture thread. Send me a PM if you want to chat about it.
