Document 14: Arsenal F.C.: Arsenal's longest-running and deepest rivalry is with their nearest major neighbours, Tottenham Hotspur; matches between the two are referred to as North London derbies. Other rivalries within London include those with Chelsea, Fulham and West Ham United. In addition, Arsenal and Manchester United developed a strong on-pitch rivalry in the late 1980s, which intensified in recent years when both clubs were competing for the Premier League title – so much so that a 2003 online poll by the Football Fans Census listed Manchester United as Arsenal's biggest rivals, followed by Tottenham and Chelsea. A 2008 poll listed the Tottenham rivalry as more important.
Document 15: Arsenal F.C.: Arsenal fans often refer to themselves as "Gooners", the name derived from the team's nickname, "The Gunners". 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. Arsenal have the seventh highest average attendance of European football clubs only behind Borussia Dortmund, FC Barcelona, Manchester United, Real Madrid, Bayern Munich, and Schalke. The club's location, adjoining wealthy areas such as Canonbury and Barnsbury, mixed areas such as Islington, Holloway, Highbury, and the adjacent London Borough of Camden, and largely working-class areas such as Finsbury Park and Stoke Newington, has meant that Arsenal's supporters have come from a variety of social classes.
