Backpass rule selectable in KO2CV menu.
This was quite quick to do. It's not totally correct from a FIFA rules point of view, but certainly does the job.. The keeper is unable to touch the ball if someone else on his team was the last to touch it. He doesn't have the option of kicking or heading the ball instead of using his hands(yet), but just stands helplessly as his defender rolls it into his net.

In theory, Barber could thump the ball through Cox (who gets a touch) and Fisher would be unable to stop the ball rolling over the goal line. Sweet.
