The Side-Foot Pass

You will play this pass more than any other. Keepers now use their feet far more than their hands, and most of those touches are a side-foot pass.

Two touches, both feet

Standing foot: Beside the ball, pointing at your target. Where it points is where the ball goes.
Ankle locked: Toe up, heel down, foot turned out like a golf putter. A loose ankle gives a weak pass.
Middle of the ball: Strike through the centre to keep it on the grass. Underneath it and the ball bobbles up.
Follow through: Your foot keeps going towards the target after the ball has gone.
Pace on it: Firm enough that a striker cannot nip in, soft enough that your team-mate can control it.

Common mistakes

Leaning back, which lifts the ball.
Standing foot too far behind the ball.
Passing to where your team-mate is, when they are running. Pass in front of them.
Standing still after the pass. As soon as it leaves, move so they can pass back to you.

Practise it with Wall Work, Keeper Rondo, Open Up.
