Save penalties as the keeper. Stay big and balanced, read the taker, delay the dive so you do not commit early, and spring low and strong to keep it out.
Takers strike penalties and the keeper works on saving them. Stay big on the line, read the run-up and body shape, delay the dive, then spring low and strong to the corner. Vary the placement. Emphasise not committing early and a powerful, low dive. Rotate takers to vary the picture.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
