    There is this game - played all over the world - called soccer. We play soccer in matches and we learn, improve, and refine soccer in training. Official regulations and playing rules define a match. In match-play, it is about performing and winning. The training is designed to emphasize and mimic specific situations of the match. In training, the focus is on learning. This thesis will focus on the relation between the match and training: can we replicate match behavior in training?

    Football is a simple game: twenty-two men chase a ball for 90 minutes […].

    Gary Lineker - 1990

    Official soccer match

    Twenty-two players, representing two opposing teams, play soccer on a 105 x 68 m pitch with a ball, regulated by playing rules. This combination is specific for soccer and shapes the behavior of players during an official match (Glazier & Robins, 2013; Newell, 1986). A logical purpose of soccer is to win the match by scoring more goals than the opponent does. Players employ a combination of their physical, technical, and tactical capacities to reach this goal (Jones & Drust, 2007). However, there is a conflict in the relation between players present on the pitch: ball possession entitles players to attack and score a goal, but opponent players will make every effort to prevent that. This creates cooperation of players within a team and competition between players of opponent teams (Grehaigne, Bouthier, & David, 1997; McGarry, Anderson, Wallace, Hughes, & Franks, 2002). Moreover, teams try to score on different sides of the pitch. This oppositional relationship produces goal-directed behavior that goes back and forth in a predominantly goal-to-goal direction of the pitch (Frencken, Lemmink, Delleman, & Visscher, 2011; Grehaigne et al., 1997; McGarry et al., 2002).

    A main objective in soccer science is to capture this goal-directed behavior. In performance analysis, researchers quantify a player’s physical load, technical skills, and tactical decision-making in order to observe a player’s activities in the real context of the match, instead of using field tests or laboratory experiments. Time- motion analysis is used to quantify physical load and movement activity patterns, like the distance covered, high intensity activities, and sprints. With video analysis, both technical and tactical skills can be observed. Technical skills are mostly determined by quantifying (successful or direction of) actions on the ball (Hughes & Bartlett, 2002; Vilar, Araújo, Davids, & Button, 2012), where tactical skills are mostly related to qualitative observations of decision-making (van Maarseveen, Oudejans, & Savelsbergh, 2017). At this point it is important to note that soccer players are considered as the performers

    of the game (Glazier & Robins, 2013). In order to use consistent terminology throughout the thesis, a player’s individual contribution to the game (in the physical, technical and tactical domain) will be called ‘performance’. This is a commonly used term in soccer science literature, along with other terms like capacity, skill, demand, performance outcome, outcome of behavior, etc.

    Thus far, performance analysis literature mainly gave insight into a player’s individual soccer performance. However, soccer is by definition a team sport with an intermittent character where teams alternately attack and defend. Moreover, it is characterized by its (temporary) interactions between players, formation of sub-groups, and unpredictability. Rather than a limited focus on only individual performance, soccer science can benefit from a more comprehensive understanding of soccer performance, including analysis on a team level (Vilar et al., 2012). An ecological approach, such as the dynamical system theory, enables capturing and identifying collective behavior (Grehaigne et al., 1997; Seifert, Araújo, Komar, & Davids, 2017). A player’s interaction with team members, opponents, and the environment define collective behavior (Grehaigne et al., 1997; McGarry et al., 2002; Seifert et al., 2017; Vilar et al., 2012). Such an ecological approach enables researchers to model and understand how players choose position and how teams organize and coordinate with respect to their opponent. In soccer science literature, collective behavior is also described as team tactical behavior. In this soccer context is team tactical behavior defined as the individual and collective actions of a team to best employ player skills in order to contribute to the team’s goal of attacking and defending by goal scoring or preventing goals (Carling, Williams, & Reilly, 2005).

    Collective behavior can be described as the dynamic relation at individual and team level, displayed as player-player (or dyadic), intra-team, and inter-team coordination. Dyadic coordination reflects the player’s interaction with a team member or opponent player and is often displayed as the distance between two players (Bourbousson, Sève, & McGarry, 2010a; Gonçalves et al., 2017; McGarry et al., 2002; Vilar et al., 2014). Intra-team and inter-team coordination reflect the cooperation within a team or competition between t
