Coaches spend an awful lot of time teaching tactics, often telling players, for instance, that they need to stay in their positions. But what's sometimes lost is the fact that soccer is a free-flowing expression of how you want to see the game unfold.

As a coach it is natural to have your "favorite" players. However, the positive and negative expectations you form about players on your team affects not only your own behavior toward them but also the feelings and performance of those players.
