In times of economic difficulties, sport looks for various streams of revenues and funding, and in some cases, turning to public bodies represents the only viable solution. In turn, funding of sport enterprises and professional clubs may pursue public policy objectives or may be used as a political tool for local municipalities and national governments. However, EU law has to protect the competition on the internal market, even against measures taken by Member States. Article 107 TFEU prohibits any type of public measures granted by Member States which distort or threaten to distort competition by favouring certain undertakings or the production of certain goods. This chapter offers an overview of the recent Decisions of the EU Commission on the legality of measures granted by Member States to fund professional sport clubs. Moreover, the chapter discuss the General Block Exempting Regulation for funding of multi-functional arenas.
