While the links have been quietly accumulating in the sidebar, I'd like to mention one site in particular, whose unflashy name, Must Read Soccer, belies how interesting it is. Essentially a clearing house for anything written on football that catches its author's eye, even a cursory check throws up:
Andrew Guest's On the Invention of Tradition - referencing Terence Ranger and suggesting an alternative motivation for Sepp Blatter's defence of the vuvuzela (although it also suggested to me a possible counter-narrative in which the vuvuzela is a kind of sod-casting, a Deleuzian territorialization of the space of the stadium and the space of fandom).
Jonathan Wilson on Uruguay's garra
Tim Vickery on the emotional immaturity of Maradona and (less predictably) Dunga
...and the World Cup read through Moby Dick
