Aberdeen's average attendance is higher this year than it was the year Aberdeen took 40,000 to Celtic park. There isn't really a drop off in support, Aberdeen's average home attendance has never been spectacular but it is better this season - down to Europe IMO
The 40K to Glasgow was a one off and there were many factors for this. almost 20 years since the last trophy, a real chance of winning it with no OF opposition in the final. A brilliant semi final performance against St Johnstone with one of the best atmospheres I have seen at tynecastle. The best league form in years after being shit for years, a competent manager after years of having jokers at the helm.
