Figure 2.
Relative ball touch frequencies for each player in each 5-min interval.
The goalkeeper, defender, midfielder, and forward are denoted as G, D, M, and F, respectively. The color gradation from red to white corresponds to an increase in the relative frequencies of ball touch from 0% to 50%. a–d. Italy, France, Japan, and Ghana, respectively.
Figure 3.
Game momentum, represented by the number of triangles in each network.
a, Upper panel shows the number of triangles for each team during each 5-min interval of the 2006 World Cup Final. Differences between the numbers of triangles for both teams in each 5-min interval are shown in the lower panel as a bar chart. A green bar shows that the number of triangles was greater for Italy than for France, and a blue bar shows that France generated more triangles than Italy. The attacking phase also includes the shots added to the lower panel as green and blue arrows for Italy and France, respectively. The thick and thin arrows show the shots and the successful attacks without the shots, respectively. b, The case of the 2006 Kirin Challenge Cup shown in a manner similar to that for the 2006 World Cup in panel a. Fisher's exact tests were applied to determine whether more triangles generated by a team correlated with the more attacks during that time period. The -values for this correlation were 0.087 for the World Cup and 0.024 for the Kirin Cup.
Figure 4.
Wiring diagrams for a football game.
All diagrams represent each player as a vertex and each pass as a link in each 5-min interval in the first 20 min of the first half. The size of each vertex shows its degree. France received a penalty kick and scored in the seventh minute. Italy scored in the 19th minute after a corner kick. The black line shows the tracking of the ball handling during each 5-min interval for the same team. a. Intra-group network for Italy. b. Inter-group network for both teams. The gray line also shows the tracking of the ball between teams. c. Intra-group network for France. G, D, M, and F denote goalkeeper, defender, midfielder, and forward, respectively, according to the 4-4-2 system of play, regardless of the system actually chosen by each team.
