Figure 1.
A rotation matrix was applied rotating the data through an angle θ.
A rotation matrix was calculated from the field vertices and applied to the players' positions, rotating the data through an angle θ in order that the longitudinal displacements were aligned with the x-axis and the lateral displacements were aligned with the y-axis.
Figure 2.
Standardized effect sizes and 95% CI of pairwise differences between opposition levels for time motion (a) and intra-team synchronization (b) variables.
Positive values represent superior results in matches opposing the higher-level team.

Percentage of time of dyadic synchronization according to the opposition level.
a) Longitudinal and b) lateral displacements for the whole analysed half and by different movement speed categories. *: Significant differences at p<0.05.
Figure 4.
K-means clustering of players' according to the percentage of time of dyadic synchronization.
a) Longitudinal and b) lateral displacements of defenders (D), midfielders (M) and forwards (F). Solid lines represent the higher synchronization group; dashed lines represent the intermediate synchronization group; dotted lines represent the low synchronization group.
