Create a free header from a corner with a blocking run. Screen the target's marker as he peels off, deliver into the space he runs into, and attack the ball unmarked to score.
From a corner, a teammate makes a blocking run across the target's marker as the target peels off to the space. The corner is delivered to the free man, who heads it at goal. Emphasise the timing of the block and the peel, and delivering into the space. Rotate the roles and vary the target area.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
