We can observe an ongoing external, as well as an internal, juridification of football, which means that the legal system and a legal rationality has become to an increasingly degree mixed up with football. Whether applying an internal or an external perspective the juridification process and the regulation can be understood as an outcome of the increasing commercialization and professionalization of football. In the wake of the commercialization process various clubs have suffered, and still suffer, from overspendings, in Sweden as well as in other European countries. In this respect, the regulation of football licenses in Sweden, which was introduced in 2001, constitutes the main subject in this essay. The regulation was introduced by the Swedish Football Association, mainly as an internal response to the acceleration of expenses in Swedish football. By focusing on football licenses and their regulation the essay intends to shed light on the 'internal juridification of sport'. And by taking a departure in a socio-legal perspective, the regulation will be connected to a reflection on its impact on the development of football.
