The approach of complex systems as a form of new approach provides an opportunity to replace the dominant, mechanistic view of sport-related phenomena. By analyzing the micro and macro relationships of complex system components, the observer can describe well the set of states of the system. The transition between these states can be induced by internal and external forces. Understanding the motivations of smaller groups and successfully integrating this knowledge to understand higher-level elements of the system facilitates the understanding of complex transitions. The novelty is in this research that micro and macro changes are integrated as a common driver and they generate something entirely new property for the whole system. In a case study, a small soccer team is presented as a complex system. There are statuses examined and elaborated in which this small team and the members go through the observed period (2005-2009) which can be similar to other complex systems. The case study successfully mirrored the behavioural dynamics of agents in a social neurobiological system, exemplified by interactions of statuses in a team sport.
