The near-post flick routine with an open goal, no keeper or defenders. Emphasise the pattern and timing, the flat delivery, the near-post flick across goal, and the back-post run arriving on time. Build the habit before adding pressure. Rotate the roles.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
