This study examines the relationship between financial conditions and on-field success among 36 prominent European football clubs from 2010 to 2017. The research employs panel regression analysis to explore how clubs’ financial indicators such as wage costs, increasing revenues, debt-equity ratios, and return on assets correlate with their sporting performance. The findings suggest a substantial association between these financial factors and the clubs’ achievements. In particular, the results emphasize the importance of wage costs and increasingrevenues in boosting a club’s capacity to invest in high-quality players, thereby improving sporting outcomes. The presence of a top globally ranked player also has a significant impacton a club’s performance. These findings carry important policy implications for club management and governing bodies, particularly in revising wage regulations and promoting vigilant financial management for sustainable growth and competitiveness.
