The 4-2-3-1 has two holding midfielders, the double pivot. In build-up they should never stand side by side. One drops near the centre-backs to receive, the other stays higher to link, and the number 10 floats in the pocket behind their midfield. With the full-backs pushing on, there are passing lines at three different heights.
Step 1 of 5
Goal kick against a 4-4-2. Our double pivot staggers instead of standing side by side.
The two holding midfielders in a 4-2-3-1. In possession they stagger so one is always free; out of possession they protect the defence.
Where should the 10 stand when we play out?
In the pocket between their midfield and defence, slightly to the side of the ball.
What if we keep losing the ball when we play out?
Expect it at first. Keep the shape, practise the same patterns in training under light pressure, and judge the decision rather than the result. If a game is getting away from you, it's fine to mix in a longer pass to the striker for a spell.
