The four groups, in plain language:
Goalkeeper: the only player who can use their hands, and only inside their own penalty box. The goalkeeper defends the net. At youth levels, this role rotates frequently and should.
Every kid benefits from playing goalkeeper at some point. It changes how they read the field.
Defenders (also called fullbacks or center backs): they play in front of the goalkeeper. Their primary job is preventing the other team from shooting. At 8-10, you will see kids line up in a back-three or back-four.
Their first job when the other team has the ball is to get goal-side, meaning between the attacker and their own goal.
Midfielders: the players in the middle of the field. They are expected to do both things, defend when the other team has the ball and attack when their team does. Midfielders cover the most ground.
Central midfielders control tempo. Wide midfielders (or wingers) run the flanks and deliver crosses into the penalty area.
Forwards (also called strikers or attackers): they play closest to the other team’s goal. Their job is to score, and to create chances for teammates to score.
The center forward plays centrally. Wide forwards stay wider and look for opportunities to cut in or cross.

The players who end up in permanent positions at 13-14 almost always benefit from having played multiple roles at 8-10. It is how they develop the full-field understanding that coaches need from them la
