Keep the ball in a 6v3 and play with purpose. Support at angles, move the ball to shift the three defenders, and split them with a line-breaking pass across the box when the gap opens.
Six players around a box keep the ball against three defenders. Support at angles and move the ball to shift the three, then split them with a firm pass across the box when the gap appears. Two touch on the outside, one touch when you can. Rotate the three defenders after a set time or number of splits.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
