Train the long switch as a deliberate tool rather than a last resort. Players work the ball away from the target to drag the shape, combine to escape pressure, then find the far side and attack the goals from the space that has opened.
Set three pairs of mannequins as lines across a 35x23m area, with a central pole gate and two mini-goals side by side at one end. Start with the ball near the goals. Work it away with a carry and a wall pass, then hit a long pass to the far side, combine there, and switch it back through the lines to finish in either mini-goal. Send the next ball as the previous sequence reaches the far side, so two waves are always running. Rotate players through every station.
Possession drills tend to reward the nearest pass. Keep the ball, find the free man, repeat, and after a while a group gets very good at circulating in a small area and no better at doing anything with it.
The structure here forces the opposite habit. The target goals sit at one end, and the pattern deliberately takes the ball away from them, nearly twenty metres in the wrong direction, before bringing it back. That sounds inefficient and it is exactly what good sides do: the ball goes to one side to make the opposition shift, and the goal is scored on the other. Practising the journey, rather than just the final pass, is what makes the habit stick.
The three lines of mannequins are what stop it becoming a passing rhythm. Every significant transfer has to go through or around something, which means the receiving player's body shape matters on every touch. Receive the long ball square and the return journey costs an extra touch, by which point the imagined defensive line has reset.
Running it in waves matters more than it appears. A single ball means seven of the ten players are watching at any moment, and watching is where habits go to die. With a second wave starting as the first reaches the far side, players are constantly either involved or about to be, and the tempo is set by the exercise rather than by whoever happens to have the ball. It also stops the group treating each sequence as a set piece to be performed neatly, which is the failure mode of every patterned possession drill.
Save it to your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block. Or start from a blank pitch and build your own.
