We do love maps here at CultFootball. Via bigthink.com (which got it from qprdot.org), a great map of London:
For reference, here is a Google Map of London showing the grounds of the five London Premier League clubs:

Some commentary by the BigThink writer (Frank Jacobs, author of their Strange Maps sub-blog):
It shows the clear geographical slant of football fandom in the British capital: the centres of gravity for each ‘fanland’ tend to be around the home grounds of each team.
As with other fan loyalty maps, this one has a decidedly feudal feel to it. None of the clear, straight delineations of modern borders, but lots of fuzzy boundaries, transitional zones, and enclaves in ‘enemy’ territory.
Some teams command great swathes of territory, for example West Ham United FC. This Premier League club dominates the east of London, in particular the boroughs of Havering [Ha], Barking and Dagenham [BD], Redbridge [Rb], Newham [Nh] and Tower Hamlets [TH].
Barking and Dagenham, West Ham heartland, contains an enclave where loyalty is shared with Dagenham and Redbridge FC, recently promoted from Football League Two to One. However, theDaggers are – literally – not in West Ham’s league; loyalties for both teams therefore probably are complementary rather than conflictual.
Other fanlands are more compact than West Ham’s, like that of Fulham FC. From Craven Cottage, its grounds on the banks of the Thames, this club commands an undisputed, but relatively small territory in the boroughs of Hammersmith and Fulham [HF] (north of the river), most of Wandsworth [Ww] and part of Richmond upon Thames [RT] (both south of the river).
Nearby rival Chelsea, based at Stamford Bridge (also in Hammersmith and Fulham rather than the neighbouring borough of Kensington and Chelsea [KC]), is master of a much more fragmented, but also much larger domain, extending from its core in Kensington and Chelsea all the way north to the northeastern corner of Barnet [Ba], taking in most of Brent [Br], south to Kingston upon Thames [KT], west to Lambeth [La] (a grey zone shared with Millwall) and east to Hillingdon [Hi], an area disputed with Queens Park Rangers that extends back into Ealing [Ea], the western part of which is QPR-only territory.
Arsenal is big in its home borough of Islington [Is], and in Camden [Ca] and Barnet. It commands a similar archipelago of loyalty throughout London (4), but has to share north London with Tottenham Hotspur, which rules over most of Enfield [En], Haringey [Hr] and Hackney [Hc]. Loyalty to the Spurs seems to be confined to that area, however, except for two small patches in Westminster [W].
