Put Your Money Where Your Mouth Is: Verbal Self-Reported Tactical Skills Versus On-Line Tactical Performance in Soccer

The main goal of the study was to examine whether a relationship existed between self-reported and in situ tactical decision-making in the form of actions for small-sided soccer games, namely 4-vs.-4 and 8-vs.-8 games. Sixteen skilled male soccer players participated and completed the Tactical Skills Inventory for Sport Questionnaire (TACSIS). In addition, their decision-making performance was assessed for two 4-vs.-4 and one 8-vs.-8 small-sided soccer games. Video-analysis of the small-sided games was conducted to determine the successful and unsuccessful actions of each player. A performance ratio was calculated for each player based on the small-sided game analyses, which reflected the number of successful decisions made by players; that is, the number of successful ball actions divided by total ball actions. Correlation analysis revealed no significant relationship between the procedural knowledge TACSIS questionnaire scores and performance in the small-sided games. The findings are discussed within the theoretical framework of the two-visual system model and the repercussion for the use of questionnaires for talent identification.
