DP13927 The interdependence of domestic and international success: the case of the UEFA Champions League
This article explores interdependence of domestic and international success in sports
where leading clubs enter international competitions while competing in their domestic
leagues. Taking as starting point the success of Spanish football teams in the UEFA
Champions League during the 2008-2018 decade, we provide a stylized game-theoretical
model in which national competitions determine the level of competitive balance therein.
We rationalize the hypothesis that intermediate levels of competitiveness within domestic
competitions are instrumental in achieving international success.
