Use the false-nine drop to create and exploit space. Drop off to receive and drag the marker out, then slip a runner into the space behind before the defence adjusts.
The centre-forward drops off the front line to receive between the lines, dragging his marker out, and a runner attacks the space vacated behind for a through-ball and finish. Emphasise the nine dropping into a real pocket, a runner reading the vacated space and timing the break, and a quick through-ball before the defence recovers. Rotate the roles.
Vacating space is worthless if nobody attacks it. This is the failure mode of every false-nine session and it is worth watching for from the first repetition: the striker drops into the pocket, receives beautifully on the half-turn, and the space he has just created behind the centre-back stays empty because his teammates are watching him rather than running. The drop is only half a pattern.
The dilemma is what the drop manufactures. A centre-back facing a striker who drops has two options and both are bad. Follow him, and he leaves a hole in the defensive line for somebody else to run into. Hold the line, and the striker has time and space between the lines to turn and pick a pass. A defender choosing correctly does not exist here, which is the whole appeal.
Which means the response should be coached according to which choice the defender made, rather than as a fixed sequence. If he follows, the ball goes over or around him into the vacated space, immediately. If he holds, the nine turns and plays, and the runners become an option rather than the plan.
Dropping into a genuine pocket matters. A striker who drops so deep he is standing next to his own midfielders has not created a dilemma, he has just left the pitch's most dangerous area unoccupied and joined a crowd.
The honest requirement is a specific kind of forward. This asks a striker to be a passer, comfortable receiving with his back to goal and content to create rather than score. A penalty-box finisher asked to play here will do it badly and enjoy it less.
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.
