Is an organisation's performance necessarily dependent on its financial resources?

Background / Purpose Despite a growing body of research on football club performance, the conditions under which financial capacity translates into sporting outcomes remain underexplored. This study investigates how financial resources influence the sporting performance of European football clubs participating in the UEFA Champions League, and through which intermediate mechanisms this relationship operates.Methods A quantitative study employing structural equation modelling (SEM) was conducted on 496 club-season observations drawn from 107 clubs across 33 European countries, covering 18 Champions League seasons (2004–2005–2021–2022). Data were sourced from official club publications and the specialist sports press, log-transformed, and standardised prior to analysis.Results and Findings Financial resources do not exert a direct effect on sporting performance; rather, their influence is fully mediated by the recruitment of star players. Star players constitute the sole resource category with a significant direct positive effect on sporting performance. National trophy success indirectly supports European performance by enhancing a club's financial attractiveness and its capacity to recruit stars.Implications Club directors and sporting managers should prioritise star player recruitment as the primary lever for Champions League success, rather than treating budget expansion as an end in itself. National competition strategies merit reconsideration, as domestic success generates the institutional attractiveness that underpins access to elite human capital. Theoretically, the study advances resource-based view scholarship by specifying the mediating role of human capital quality in translating financial resources into competitive outcomes.
