You want football positions explained, but not the lazy version — "the striker scores, the defender defends." The jobs that actually win matches are the ones nobody claps for and most coaches never name.
The player who tidies up in front of the defence and gets none of the credit. The full-back who's really a match-winner. The lone forward whose job is to hold the ball so others can arrive. The number 10 who wins you games and loses you your shape. Get the right kid into the right role — and frame it so they're proud of it, not punished by it — and your team transforms without a single new signing, because you haven't got any signings, you've got whoever turned up.
This cluster covers the roles worth understanding, plus the most criminally ignored free goals in the game: set pieces. A third of goals come from dead balls and most grassroots teams spend nought minutes on them. Madness. There's a guide on corners your U10s can actually execute, and one on the long throw — a corner you're allowed to take with your hands.
Find the right job for each kid. Then nick the free goals everyone else ignores.
