Analysis of goalkeepers’ defence in the World Cup in Korea and Japan in 2002

Abstract

The purpose of this study was to examine the characteristics of goalkeepers’ defence interventions in parallel with the type of opponent attack, the area of the last pass of attack, the shooting zone most often used, the body part most often used for the last pass or for shooting, and the technical and physical actions most often used for carrying out defensive technical skills. The sample consisted of 34 goalkeepers from the national teams that participated in 54 matches of the 2002 World Cup in Korea and Japan. The matches were analysed by systematic observation. A reliability kappa index of 0.95 was established between observers. The variables studied were: type of opponent attack, area of last pass of attack, field zone from which shot was taken, body part with which last part of attack or shot was made, zone of goalkeeper intervention, defensive technical and physical actions of goalkeeper intervention. Results related to opposing team's attacks showed that teams most often used positional attacks and the last pass came from the far zones. The foot was the body part most often used to finish the attack. Upon analysing the shots taken, we found that in relation to shooting angle, the central zones are the ones that are most utilized, and in relation to shooting distance, similar percentages were found in the zone outside the penalty area and the zone situated between the penalty area line and the goal area line. Results related to goalkeepers’ defence showed that the penalty area was the zone most often used, and the defensive actions most frequently used were the save, followed by foot control, and then the clear out. Our data provide reference values to adapt the training of goalkeepers to the characteristics of the competition.
