Setup. Pairs 10 metres apart with one ball. At home, swap the partner for a wall and stand 5 metres back.
How it runs. Pass along the ground. Receive with one foot, pass with the other. Ten passes, then swap which foot receives. Round two is one touch. Count your clean passes in 60 seconds and try to beat it next time.
Make it harder. One touch only. Then weak foot only. Then your partner calls "left" or "right" as the ball is travelling.
With 4 keepers. Two pairs side by side.
We do this in session 1, The Basics.
