paragraph_text: 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.

paragraph_text: In August 2011, Arsenal suffered their heaviest league defeat in 84 years as they lost 8 -- 2 to Manchester United at Old Trafford. Arsenal had not lost a league game by such a margin since 1927 when they lost 7 -- 0 to West Ham United in the old Football League First Division. This was also the first time they had conceded eight goals in a game since 1896, when they lost 8 -- 0 to the now defunct Loughborough in the old Football League Second Division.

It was speculated that he would move to a club overseas, but signed for the Manchester club, the first Arsenal player to do so since Viv Anderson in 1987. Ferguson called Wenger to push through a deal when he learnt of the contract situation. Van Persie was instrumental in United's league win of 2012 -- 13 -- Ferguson's last, and coincidentally received a guard of honour by his former teammates before United faced Arsenal at the Emirates in April 2013.

They turned professional in 1891 and joined The Football League two years later. They were promoted to the First Division in 1904 but financial problems meant they were liquidated and reformed.

Another film reference to the club's defence comes in the film Plunkett & Macleane, in which two characters are named Dixon and Winterburn after Arsenal's long-serving full backs – the right-sided Lee Dixon and the left-sided Nigel Winterburn.
