The development of young athletes is a complex process characterised by dynamic changes and uncertainty [Abbott, A., Button, C., Pepping, G.-J., & Collins, D. (2005). Unnatural selection: Talent identification and development in sport. Nonlinear Dynamics, Psychology, and Life Sciences, 9(1), 61-88]. Talent development systems are characterised by a high level of uncertainty and unpredictability related to future outcomes [Phillips, E., Davids, K., Renshaw, I., & Portus, M. (2010). Expert performance in sport and the dynamics of talent development. Sports Medicine, 40(4), 271-283]. This complexity means that attempts to identify sporting talent and to predict who will eventually succeed have a low level of success [
