Youth Soccer
Youth soccer should scale the game to the player, not force children into an adult version too early.
U11 / 9v9
Start with U11 Soccer Rules for the U.S. 9v9 context, including the build-out line, offside, goalkeeper distribution and local-rule variation.
Training
Use:
Position development
Youth players benefit from solving different problems. A defender should experience attacking situations; a forward should learn to defend; midfielders should not be the only players asked to scan.
Editorial rule
Age-group pages must separate national development standards from local competition rules. Never invent universal U9/U10/U11 match durations, roster limits or substitution rules.
