I want to know the answer to the following question:
Why were the English clubs banned from European competition in the 1980's?
All the background I'm provided with is that "The Football League First Division, which had been the top level of English football since 1888, was well behind leagues such as Italy's Serie A and Spain's La Liga in attendances and revenues, and several top English players had moved abroad.". Is that enough to answer the question?
Answer: no
