Rivalries
Arsenal's longest-running and deepest rivalry is with their nearest major neighbours, Tottenham Hotspur, with matches between the two being referred to as North London derbies.
Matches against other London sides, such as Chelsea and West Ham United are also derbies, but the rivalry is not as intense as that between Arsenal and Tottenham. In addition, Arsenal and Manchester United have had a strong on-pitch rivalry since the late 1980s, which has intensified in recent years when both clubs have been competing for the Premier League title.
A 2003 online survey found that Arsenal supporters most dislike Tottenham Hotspur, followed by Manchester United and Chelsea, although both Chelsea and Spurs fans see Arsenal as their main rival.
