There is an apt description of the game of soccer which says it's like chess in motion. Visualize, for a moment, a chessboard where every piece can decide on its own what, where, and when to move! That pretty well describes the game of soccer. Once a game starts the players are on their own.
All of which means it's near impossible to coach a soccer game from the sidelines. If the players haven't learned their drills, footwork and movements in practice they are not going to learn them from sideline coaching during the game.

The major negative of trying to coach from the sideline is that it interferes with and disrupts the flow of play, causes confusion and breaks player focus.

The fact is that players are in control of their own performance once the game starts. Well……. not quite. If coaches can't control the play from the sidelines, it by no means relegates them to being mere spectators. Here are three major, critical, contributions every successful coach can make from the sidelines.

Bottom line: if coaches can't control all the variables of their individual players, not to mention the those of the opposing team, it still remains in their control to exhibit the most powerful factor a coach can bring to the team, encouragement.
