Attack as a unit against an organised defence. Play through midfield rather than around the outside of the practice, move the ball to the flank to unbalance the block, deliver early, and time the arrival in the box.
On half a pitch with a goal at each end, an attacking unit plays against a defending unit and keeper. Start with a fullback, limited to two touches and required to play into midfield. The defending team scores by attacking the far goal as soon as they regain it, with a short time limit to make them counter rather than just clear. Overload the coached team if you want a cleaner picture (9v8, 8v7), and vary the start position to rehearse different scenarios.
Somewhere between a drill and a match there is a format most sessions skip. A drill rehearses a movement with no opponent making decisions. A match contains everything at once and repeats nothing. A phase of play sits in between: one direction, one part of the pitch, a real organised defence, and the same situation arriving again and again until players stop solving it by accident.
That is the only setting in which attacking a set defence can actually be practised, because in a full game the situation arrives perhaps a dozen times and never twice the same way.
The instruction that decides whether it works is to play through midfield rather than around the practice. Given a bounded area, players will exploit its edges, running down the outside of the exercise where no defender has been placed, which produces attacks that would not exist against eleven opponents. Coaching that out early is what keeps the phase honest.
Moving the ball wide to unbalance the block before attacking it is the pattern being rehearsed, in that order. Going wide first and attacking a block that has not shifted is the most common wasted repetition.
Delivering early rather than taking the extra touch near the byline is where the phase usually breaks down, because the extra touch feels safer and gives every defender another second to organise.
Be honest about the cost. This needs numbers, it involves standing between repetitions, and twenty minutes will produce maybe fifteen attacks. It is expensive, and for rehearsing the final third against a real defence there is no substitute.
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.
