A Review of Competitive Balance in European Football Leagues before and after Financial Fair Play Regulations

Abstract

This paper analyses competitive balance in 24 top-division domestic football leagues in Europe before and after the implementation of UEFA’s Financial Fair Play (FFP) regulations. Our analysis covers 22 seasons between 2000/01 and 2021/22 and utilises indicators of overall league concentration and dominance. Seven of the 24 leagues examined have seen a statistically significant worsening of league concentration post-FFP, fourteen leagues experienced a decline in the number of top-four finishers and thirteen saw a reduction in the number of unique title winners. The weight of evidence indicates that FFP has adversely affected competitive balance in several European football leagues.
