||For fans of pro soccer in Mexico City, the four most popular teams represent distinct identities that embody such attributes as political power, nationalism, and working-class values. One of these teams, the Pumas, is associated with youthfulness, and its equally youthful fans take pride in the fact that their heroes have not yet been corrupted by corporate or political interests. This ethnographic study examines Puma fans’ understanding of the ideal that the team represents, considers the practices they employ to express and sometimes contradict this ideal, and reveals how soccer fandom in contemporary Mexico has emerged as a nexus of tensions among competing visions of state and society.Roger Magazine takes readers inside Mexico’s soccer stadiums to explore young men’s participation in struggles over the future of that country’s urban society.
