An ethnographic case study design is applied through participant observation of 10 under’7 football teams during a school year and semi-structured interviews with their teachers. The analysis of qualitative data shows that the role that players assume incipiently in their teams is oriented toward performance and it has implications on their self-esteem. The expectations of the adult environment affect the way in which the personal success of each player is assessed according to their role. It is discussed the relevance of rethinking the way in which sports-training practices are offered in school sports so that expectations converge with the particular potential of each child.
