Tactics & Strategy

The numeric arrangement of the players on the pitch and the logical distributions of those players covering the width, Length and Depth of the field is called system of play or formation. 
Defining roles and responsibilities (in attack and defense and/or in specific area of the field)  for the players in order to provoke a successful result is called tactic. Tactics can also include a game plan to provide the players with a specific plan of action, designed to achieve a desired result, or to enhance the personalities of the players on the field to give them the greatest opportunity to succeed.
Coaching Tactics:
It is extremely important that all players understand how to play tactically during attacking and defending actions of the game. The ability of players to perform tactically throughout the game depends upon the close relationship between technique, fitness, psychology and tactics. These components are interrelated and must be applied together during training to obtain the highest level of performance. At the highest levels, the game has become very complex and training must not only meet the demands of the game but also, strive to exceed those demands on both sides of the ball. Teaching tactic progress...
• Individual Tactics — Teaching the player to play with and without the ball, i.e., attacking players vs. pressuring defender. This is where the importance of the individual duel is first introduced. A player’s individual brilliance on either side of the ball can be significant to the outcome of the game.
• Group Tactics — Two or more players join to become effective tactical groups around the ball. Group tactics can be any combination of small groups such as 2v1, 2v2, 3v2, 2v3, 4v4, etc. A general rule for group tactics is to have one more player than the opponent on either side of the ball. This is referred to as playing numbers up.
A general method of teaching group tactics is - unrestricted space, restricted space, to one large goal, to one large goal with a counter attack goal (goal, target, lines, player) and finally to two large goals.
Although this is the general method, teaching can begin at any step based upon the ability of the players and demands of the game.
• Team Tactics — Team tactics address the team’s playing objectives and the roles and functions of the players. Players are taught their responsibilities in both attack and defense within the thirds of the field (safety\risk factors.) Team tactics include half field activities such as 6v4 or 6v5, with both teams organized within a playing system. Practice should progress to full field activities such as 9v9. Specific restrictions can help to imprint a tactical plan, e.g., number of touches, number of touches in specific areas of the field. Restarts on both sides of the ball also need to be addressed.
• Tactical Functional Training — Training that is specific to a role or position. Training takes place in the area of the field where the player operates. The player determines which skill is necessary to solve the demands of the game as dictated by the game. Decision making is the essence of this method of training.
