Achieving sustained success, both on and off the field, depends on a deep understanding of the economic factors at play, particularly the relationship between financial investments, such as personnel costs, and sporting outcomes. This article explores the intricate economic links between spending and performance, drawing on insights from Mads Davidsen and Dan Hammer's book "How Hard Can It Be?" as well as academic research. We will also discuss the risks associated with overinvestment, particularly for Polish football clubs, and the strategic decisions that can ensure long-term stability and success.
The Importance of Salaries for Sporting Success
Academic research has consistently shown a strong correlation between a football club's wage expenditure and its on-field performance. This relationship is well-documented across various leagues, highlighting the critical role of financial investment in determining a club's success. For instance, Szymanski and Kuypers (1999) demonstrated that wage bills accounted for a significant portion of the variation in league standings in English football, a finding corroborated by further studies in other European leagues. Garcia-del-Barrio and Szymanski (2009) revealed that wages could explain approximately 90% of the variation in sporting success, underscoring the importance of financial power in modern football.
However, while the overall correlation between wages and performance is strong, it's important to recognize that this relationship can exhibit significant variability on a season-to-season basis. Research indicates that short-term factors such as injuries, managerial changes, and fluctuations in player form can lead to greater variance in league positions, even among clubs with similar wage expenditures. This phenomenon suggests that the correlation between wages and league position is less pronounced over a single season compared to a longer time frame.
Supporting this observation, Peeters and Szymanski (2014) argue that the short-term nature of football seasons introduces a level of unpredictability, where factors unrelated to wage expenditure can temporarily overshadow the influence of financial resources. As a result, while clubs with higher wage bills generally perform better over time, the variance in league standings can be greater in individual seasons, weakening the direct link between salaries and performance in the short term.
This increased variance on a seasonal basis is also discussed by Gerrard (2005), who highlights that the impact of non-financial factors—such as tactical decisions, fixture congestion, and even luck—can cause significant deviations from expected performance. Over the course of several seasons, these anomalies tend to average out, allowing the underlying relationship between wages and performance to reassert itself. However, within any given season, these factors can lead to unexpected outcomes, with some high-wage clubs underperforming relative to their financial investment, and lower-wage clubs occasionally exceeding expectations.
To further explore this correlation within the Ekstraklasa, an analysis was conducted using logistic regression on data from the 2019/20 to 2022/23 seasons, provided by Grant Thornton/Deloitte. The analysis assessed the probability of a club finishing in the top three based on its relative salary expenditure compared to the league average.
The results confirmed the strong positive relationship between higher relative salary expenses and the likelihood of securing a top-three finish. Clubs with higher relative salaries, such as Legia Warszawa and Lech Poznan, showed a significantly higher probability of achieving top league positions. This trend was visualized through an S-shaped probability curve, which indicated that as relative salary expenditures increased, so did the probability of finishing in the top three.
Moreover, the analysis extended to include reference points for Malmö FF and FC Copenhagen, two dominant clubs in their respective leagues, whose relative salary expenditures also suggest a high likelihood of finishing at the top. The inclusion of these clubs reinforced the general finding that financial investment in player wages is a critical determinant of sporting success across different leagues.
This analysis underscores the importance of strategic financial planning in football. For clubs aiming for top-tier success, particularly in leagues with significant financial disparities, maintaining competitive salary structures is essential for consistent high performance and qualification for European competitions.
Economic Sustainability and Strategic Patience
This increased season-by-season variability underscores the importance of maintaining a long-term perspective when evaluating the impact of wage expenditure on sporting success. While financial investment in player salaries is crucial for achieving consistent high performance, clubs must also navigate the inherent uncertainties of individual seasons. Therefore, it is essential that clubs have sufficiently strong finances to withstand seasons where performance is below expectations, ensuring they do not need to downscale their operations.
Davidsen and Hammer identify two primary strategic paths that football clubs can follow:
Overinvestment and Misjudging European Ambitions
One of the significant risks for football clubs, is the tendency to overinvest in their squad with the hope of qualifying for European tournaments. Dietl, Franck, and Lang (2008) present a theoretical model showing how overinvestment can occur due to the intense competition among clubs. This competition often leads to what they describe as an "overinvestment problem," where clubs spend beyond their sustainable means in the pursuit of outcompeting their rivals.
An interpretation of this theory suggests that clubs frequently overestimate their chances of reaching European competitions and underestimate the risks associated with these investments. When clubs fail to qualify for Europe, the financial implications can be severe, leading to increased debt and financial instability. For example, Legia Warszawa might find this strategy risky if it fails to reach the Champions League, Europa League or Conference League, as the anticipated revenues would not materialize, jeopardizing the club's financial health. The same mechanism applies to clubs with ambitions to advance from lower divisions or those struggling to maintain their position in a higher division, as they face similar financial pressures when investments do not result in the desired sporting success.
To mitigate the risks of overinvestment and achieve long-term economic stability, Football clubs should consider the following strategies:
Strategic Path Commitment: A football club should choose a strategic direction and commit to mastering it. Consistency and expertise in one approach will help the club avoid distractions, make informed decisions, and align with long-term goals, ensuring both sports and financial success.
Conclusion
The relationship between personnel costs and sporting success is clear, but so are the dangers of overinvestment and financial instability. Davidsen and Hammer's strategic insights offer valuable guidance for clubs facing the dilemma of pursuing immediate success versus building for the long term. By focusing on sustainable practices, carefully assessing the risks of overinvestment, and diversifying income sources, Polish clubs like Rakow, Pogon and Widzew can secure a strong future. Meanwhile, clubs like Legia Warszawa must recognize the risks inherent in relying on short-term European success. A balanced, strategically aware approach is essential to ensuring both sporting and financial sustainability in the long run.
