I want to know the answer to the following question:
Has the final been won by a club outside of the top divisions?
All the background I'm provided with is that "The final has never been contested by two teams from outside the top division and there have only been eight winners who weren't in the top flight: Notts County (1894); Tottenham Hotspur (1901); Wolverhampton Wanderers (1908); Barnsley (1912); West Bromwich Albion (1931); Sunderland (1973), Southampton (1976) and West Ham United (1980).". Is that enough to answer the question?
Answer: yes
