New technological solutions have been improving match analysis systems for investigating players’ performance. Nevertheless, there still remains a large space in the collective analysis where improvements can be made, mainly in the use of automated information gathering. Therefore the aim of this case study was to propose a set of three automated tactical metrics and their respective ratios for use in investigating and estimating the tactical performance of football teams. Three official football matches of the same professional team were analyzed and Cartesian information about the position of players and the ball in the field was collected. Using such information, tactical metrics for penetration, offensive space and offensive unity were developed. The results showed that the unity principle was the tactical principle most often accomplished at the mean ratio of 0.83 and penetration was the principle performed with less success (ratio of 0.42). This case study proposes some computational indicators to evaluate the collective performance of football teams, providing football coaches with some additional information to be used to characterize their teams.
