The 3-4-3 system initially only defines the number of field players in the individual team parts. The goalkeeper is initially excluded from this counting method in the exercise title. In this 3-4-3 system presented here, the midfielders are diamond-shaped on the field. The individual team parts are indicated in lines. The first line is the goalkeeper. The second line is the three-back chain, the third line the central, the fourth the two midfielders in the half field, the fifth the offensive midfielder and the sixth line the striker trio. If the own team has possession of the ball, the goalkeeper moves between his goal and the middle of his own half of the game, so that he has a distance of approx. 20 meters to the defense chain and is always playable as a kind of libero and can intervene in the back of the defense with long balls. The field players should take advantage of the width and depth of the entire playing field if they have the ball. In this system, you play with a central defender, two full-backs in the back row, in midfield with a defensive, two midfielders in half positions and an offensive midfielder, as well as with two wingers and a central top. If you have your own ball, the staggering of four attacking players and two players in the half field means that you have a large number of play stations options to the dangerous area. If the opponent has the ball, the team moves in the defensive group in the 3-4-3 diamond formation on an area of maximum 35 x 35 meters. The defensive formation is characterized in its starting position by a line positioning (exception midfield) of the individual team parts. That the three defenders are on line, the four diamond-shaped midfielders on three different lines) and the three strikers as well. This creates five lines of defense. It is important to keep certain distances between each other, which ensures optimal defense of your own goal. These distances are usually as follows: 7-12 meters wide and 8-15 meters deep. The distances between the individual players and team parts can vary due to an inconsistent game pace, changes in the game situation or due to a temporary short game. In the team alliance, a compact, disciplined shift is aimed at, with the aim of narrowing the spaces and thus not allowing the opponent to pass into the depth on the one hand, and depriving him of the opportunity to start individual actions on the other. One of the most important tactical duel measures is to steer the ball-carrying player onto the outside lane and to get possession of the ball by double, and to direct the opening of the opposing team to the outside players by shifting the pass routes there so that only one pass is left in the middle is possible. There the player is then doubled and put under massive pressure.
