Set pieces account for 30% of goals at all levels. Most grassroots teams spend training time on attacking set pieces and zero time on defending them. A team that has never rehearsed defending a corner will concede from corners. The fix is direct: practise the routines.
The three defensive set piece priorities
1. Corner defence: The GK must organise immediately — number in the wall (or zonal positions), who covers the far post, who marks which player. The decision must be made in under 8 seconds. Drill this with the Defending Free Kicks Wall Setup drill applied to corners.
2. Free kick wall: The wall that doesn't jump together concedes. The GK calls the wall number, the post player marks the far post, and the wall jumps as a unit on "ON THE KICK!" Drill explicitly. The Defending Free Kicks Wall drill covers this in 15 minutes.
3. Throw-ins in dangerous positions: Most grassroots teams have no defensive routine for throw-ins in the final third. The simple fix: every defender marks their nearest opponent, GK organises from the back.
The common mistakes
Teams that concede from corners almost always have one of three problems: GK not organising quickly enough, the far post left unguarded, or defensive players watching the ball instead of tracking their runner. Each is fixable with a single session's drilling.
Session recommendation
The Pre-Season Set Piece Review drill covers attacking and defensive set pieces in one 20-minute block. If you're mid-season and conceding from set pieces, run this as a dedicated 30-minute set piece session before your next match.
Age-specific notes
U10–U11: Corners and free kicks at 5v5 and 7v7 are simple — GK organises, defenders mark nearest opponent. Don't over-complicate it.
U12+: Introduce the wall drill. U12 players can hold the wall organisation instruction without confusion.
U14+: Full set piece defensive organisation, including zonal vs man-marking corner variants.
