This can be done with groups of 3 to 7 - odd numbers ideally.
Let's assume a group of 5 players.
We'll have 3 attackers and 2 defenders.
The 3 attackers will have a delimited running corridor in a straight line and they will have to pass the ball from one to the others while the 2 defenders will have to try and intercept the passes. The defenders have freedom of movement.
The exercise can evolve in the types of passes in order to foster movement without the ball.
First all types of pass, then no lob passes, then only bounce passes.
If the defenders intercept the pass, they continue the exercise acting as the attacking players in numerical inferiority. The 3 attacking players now have no restriction of movement. This is to be done slowly at first, not as a fast break, to instill the idea of moving without the ball first. The speed can be adapted as the exercise goes on.
