I want to know the answer to the following question:
What aspect of the fan base is one of the  reasons for large game attendance?
All the background I'm provided with is that "The fanbase is large and generally loyal, and virtually all home matches sell out; in 2007–08 Arsenal had the second-highest average League attendance for an English club (60,070, which was 99.5% of available capacity), and, as of 2015, the third-highest all-time average attendance.". Is that enough to answer the question?
Answer: no
