Long pass with press A
A and B are opponents. B has the ball and "looses" it to M1.
This is the
signal, and A starts running along the sideline and M1 throws the ball to A,
who is pressed by B.
A ends the run with a shot and pick up the ball afterwards.
When all the players have been running once, the exercise starts again from
M2's goal and A is now defender while B is attacker.
