Does Technical Match Performance in Professional Soccer Depend on the Positional Role or the Individuality of the Player?

The aim of the study was to examine the impact of the positional role and the individuality on the technical match performance in professional soccer players.
From official match data of the Bundesliga season 2018/19, technical performance (short[<10 m]/medium[10-30 m]/long[>30 m] passes, dribblings, ball possessions) of all players who played during the season were analyzed (normative data). Five playing positions (center back, full back, central midfielder, wide midfielder, forward) were distinguished. As the contextual factor tactical formation is known to influence match performance, this parameter was controlled for. Further, those players who played at minimum four games in at least two different playing positions were included in the study sample (n = 13). The technical match performance of the players was analyzed in relation to the normative data regarding the extent to which the players either adapted or maintained their performance when changing the playing position.
When switching playing positions, positional role could explain 3-6% of the variance in short passes and ball possessions and 27-44% of the variance in dribblings, medium passes, and long passes. ... mehrMoreover, we observed large interindividual differences in the extent to which a player changed, adapted, or maintained his performance. In detail, five players clearly adapted their technical performance when changing playing positions, while five players maintained their performance.
Coaches can use these findings to better understand the technical match performance of single players and, further, to estimate the impact of a change in the positional role on the technical performance of the respective player.
