The aim of this study was to present a model which shows the efficiency of the goalkeepers’ actions in soccer based on observations of 12 direct elimination matches during the 2010 World Cup, the 2010 Africa Cup of Nations and the 2011 Copa America. Data was recorded on observational sheet template designed by the author. Goalkeepers’ actions, efficiency and reliability, during both offensive and defensive actions, were subject to examination. The study found that during offensive actions, for goalkeepers the most effective actions are those of taking control of the field of play and keeping possession of the ball. Whereas creating a goal scoring opportunity represents only a small percentage of their actions. Defensive actions are generally performed individually by goalkeepers and they are the most reliable while catching the ball.

Background: The purpose of this paper was to present cognitive models illustrating efficiency of the goalkeeper's actions in soccer based on observation of play in selected matches of the Euro 2008 finals.Material/Methods: The observation method was used in the study. The play of both goalkeepers was analysed in 7 soccer matches in a cup phase of the European Championships which took place in Portugal in 2008. The data was recorded on the authors' observation forms. Activity, effectiveness and reliability during both offensive and defensive actions were subject to this examination.Results: It was revealed that most actions of the goalkeeper are aimed at taking control of the field of play or keeping possession of the ball; creating goal scoring opportunity represents only a small percentage of offensive actions. Defensive actions are generally performed individually and the highest reliability is reported while catching the ball.Conclusions: Efficiency models of goalkeepers' actions should be used to create models of play for players representing a lower level of sports competence in order to improve the effectiveness of their game play. One should continue further study to improve a research tool so as to evaluate other, important from the point of view of the game's objectives, actions definitely dependent on team mates' behavior.
