I've told this story before, but this was the biggest away following that I've ever seen. Last game of the season and Inter had to win, to win the title. Inter had tens of thousands in the stadium, at least half the ground. The official attendance was about 75k, but I bet there was at least another 5k, if not 10k that jumped the fences/wall or forced the gates. No one could sit down in their seats as there were to many people, even the gangways were full, backing up onto the steps down to the concourse. It was mayhem outside, back in the days before the super fence at the Olimpico, and you could get right up the to the stadium without tickets.
