Back four - Shifting left

The four blue defenders A, B, C, and D move from the basic formation of the back four (in a line) to the end position shown in the diagram, which resembles a crescent shape. The ball is with player E. Positions can easily be filled with multiple players.

Player E passes the ball to the right toward the left outside defender / toward the sideline. At the moment of the backswing, the left back D runs forward toward the ball and stops it. At the same time, the other defenders shift as follows: Player C also steps out and covers D. Player B shifts parallel to the penalty area line to the left, approximately to the level of the near post, and player A to the level of the far post, approximately at the same height as B or 1 to 2 m ahead. Once the players have reached their end positions and the distances are correct, the players return to their starting positions and the exercise starts again.
