Work with a partner. Ask them to roll the ball into the center in front of the goal. Drive onto the ball and finish with the inside of your foot. Move backwards and explode onto the next ball and repeat again. Go for finesse and work off both feet.
Place the mannequin or obstacle in front of the goal with enough space to scoop over. Whilst the ball is on the move, get your foot right underneath the ball. Scoop up and follow through. Work on both feet.
