In 2009, Union of European Football Associations (UEFA) established Financial Fair Play(FFP) regulations to solve its club members’ fiscal deficits. The overall purpose of the FFPregulations was to balance income and expenditure of the football clubs while promotingyouth development and infrastructure development to ensure their long-term viability. Thecore part of the FFP regulations is the break-even analysis, which evaluates its members’financial statement; and if the UEFA finds financial losses over their permitted value, itimpose sanctions in relation to the participation of the UEFA competitions. From the viewpoint of competition law, people have questioned whether the FFPregulations violate the principle of free competition under the Treaty on the Functioning ofthe European Union (TFEU). Several provisions of the TFEU can be applied within thiscontext, which are Artice 101 of the free competition, Article 102 of the abuse of dominantpower, Article 63 of the free movement of capital, and Article 45 of the free movement ofworkers. Legal analyses of each Article showed the FFP regulations being anti-competitive;however, no lawsuit were found in relation to the claim that the FFP regulations wereanti-competitive in practice. The professional football league in Korea has been analyzing the FFP regulations of theUEFA, the Premier League, and the Japanese League to introduce its own version of FFPregulations. Further research would study UEFA’s FFP regulations in a meticulous way, andanalyze legal issues regarding the English football league and the Japanese league.
