The revenue-generating capacity of spectator team sports, especially European football, has developed significantly in recent decades. Europe's top teams, more than 700 clubs from 55 countries, have managed to generate annual revenues of more than €20 billion over the last 4 years. A significant part of European club football revenues comes from the Big 5 leagues. Of the 98 teams in the English, Spanish, German, Italian and French leagues, the top 20 clubs play a dominant role in generating revenues, accounting for 40% of total European revenues. Looking at the revenue structures, the most important sources of revenue are broadcast revenues and commercial and sponsorship revenues. Total revenues for European club football increased significantly in the pre-COVID period, averaging over 7% per year, but have slowed down significantly following the impact of COVID. The Polish league has experienced a significant decline, while the Hungarian league has seen a significant improvement in the period under review between 2017-2020, both in terms of aggregate revenues and average revenues per team. In my research, I present the development and distribution of the revenues of the Big 5, Hungarian and Polish leagues for the period 2017-2020.
