I have always taken a long-term view to player development.
Based on my observations of working with Elite players in North America since 1998 and the study visits I have made to top academy programs in England (Wolves/West Ham), Spain (RCD Espanyol/Sevilla/Malaga), Portugal (FC Porto ) and Italy (Chievo Verona) the top predictors for young players playing at the highest levels of the game are listed below. Predictors are player attributes that professional clubs look for in young players when assessing their potential.
I have validated this information through my studies in a Masters in Performance Coaching program at the University of Stirling in Scotland and my recent studies in Talent Identification through the Professional Football Scouts Association. I have also enclosed below some articles outlining what professional clubs look for in young players.
