We refer to popular football as clubs with an alternative philosophy to the traditional club model. These types of clubs, managed by their own members, challenge the football-business and are governed by an alternative model in which the fan has more involvement. It's a growing club management model that is gaining more followers over time. Clubs like Sankt Pauli, Union Berlin, AFC Wimbledon, United of Manchester FC, Red Star FC, Unionistas de Salamanca, and SD Logroñés are examples of popular football references.
