Resource-based research sustains that organisations (and thus teams) create value through internally developed and complementary acquired resources, through the management of resources and the development of routines. In this study, we advance the understanding of the impact of resources and capabilities by investigating the role of moderators on the key factors of team performance and address the question of when the whole is more than the sum of its parts. We develop and test hypotheses as to how managerial experience helps to foster the development of internal resources and group routines, to extract more value from bought resources, how internally developed resources reinforce group routines and how financial resources influence group routines, the acquisition of resources and the development of internal resources. Data consisted of 270 observations from European professional football leagues over a five-year period. The results confirm that the edifice of competitive advantage is based on a complex resource bundle based on non-obvious interactions between its elements. The complex inter-linkages, reinforcing effects and trade-offs between resources require non-obvious decisions regarding their employment and are best understood by experienced managers.
