Observational Analysis of the Execution of the “Control” Core Technical/Tactical Concept by Sergio Busquets
This paper is based on match analysis using observational methodology. Its object of study is the execution of the control core technical/tactical concept by Sergio Busquets, the FC Barcelona international midfielder. The observation instrument was developed ad hoc and was a combination of field format and category systems. The recording and coding process was carried out using the Lince software, version 1.2.1. The reliability of the observation instrument designed ad hoc was guaranteed through inter-observer matching calculated using Cohen’s kappa coefficient. Within the theoretical framework of Generalisability Theory, the observational instrument was validated and the generalisability of the results derived from the number of sequences analysed was guaranteed. Two complementary diachronic analyses were performed: adjusted residuals analysis with the GSEQ5 program and T-pattern analysis with the Theme program, version 6. The results show regular behaviour patterns in which Sergio Busquets controls the ball with his instep, positioned at the back line of his team with the forward line of the opposing team in front of him. His control also has a tactical intention, namely to switch play towards the opposite side from which the ball enters. The conclusions of this paper are a highly significant starting point for designing tasks whose purpose is to develop the “control” core technical concept on the basis of the analysis of a leading player.
