How do you coach playing against a low block in 9v9?

Against a low block, I’d coach moving the opposition rather than telling the players to be more patient. Use a directional game where the defending team protects a compact central area. The attacking team can score normally, but give them enough width and support behind the ball to recycle possession. Then ask: “What makes a defender leave the space they want to protect?” That might be switching the ball, an overlap, a player receiving between lines or somebody carrying at the block. I would avoid putting a minimum pass count on it. That can create slow possession for its own sake. At U13, the useful lesson is that not every defence can be attacked at full speed. Sometimes you move them first, then exploit the gap. Patience should still have purpose. The ball is moving because you are trying to change the defensive picture.
