Flick it on and finish at the back post. Drive the inswinger to the near post, glance it on across goal, and time the back-post run to finish the flick.
An inswinging corner is driven to the near post, a runner flicks it on with a header, and a back-post runner finishes. Emphasise the pace and flatness of the delivery to the near post, the near-post runner attacking the ball to flick it on, and the back-post runner timing his arrival. Rotate the roles.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
