Soccer has five defensive positions: goalkeeper, center back, sweeper, full back and wing back. No team plays all five at once. The formation decides which ones are on the field, and in US youth soccer so does the game format.
What do defenders do in soccer?
A defender's job is to stop the other team from getting a clean shot, and almost everything they do in a game is a version of that. When the ball is far away, they hold a shape and talk. When it gets close, they close down the attacker, cut off the pass into the striker or put a body between the ball and the goal.
Winning the ball back usually comes from reading a pass early and stepping in front of it. Tackling is the other way, and it has limits. Law 12 of the IFAB Laws of the Game makes a tackle a foul if the referee judges it careless, reckless or done with excessive force, so a defender who dives in on every touch gives away free kicks in dangerous spots. Staying on your feet is usually the smarter option, and our guide to the slide tackle covers when going to ground makes sense.
Once the ball is won, the defender's next job is to keep it. A simple pass to a midfielder is worth more than a long hopeful kick, which is why coaches spend so much time on how the back line plays out.
How many defense positions are there in soccer?
Five, counting the goalkeeper. A typical 11v11 team fields the keeper plus three, four or five of the others, depending on the shape.
Goalkeeper
The keeper is the last line of defense and the only player with a handling exception. Under Law 12, a goalkeeper can't commit a handball offense inside their own penalty area, but outside it they have the same restrictions as everyone else. The best keepers do a lot of defending with their voice, too: they can see the whole field and tell the back line when to step up or drop off. Our goalie drills cover the hands-on side.
Center back
Center backs sit in the middle of the defense, usually in a pair, sometimes as three. They mark the striker, attack crosses in the air and block shots. One often steps forward to press while the partner covers behind, and the two swap those jobs constantly during a game.
Sweeper
The sweeper plays behind the rest of the back line with no fixed player to mark, cleaning up through balls that get past the others. It's rare in professional soccer now, but you still see it in youth games where a coach wants one reliable player covering behind. The full history is in our post on the sweeper position.
Wing back
Wing backs play wide in a back three, which makes the line a back five when the team is defending. They cover the whole sideline, from their own corner flag to crossing positions in the other half, so this spot asks for a lot of running.
Full back
Full backs are the wide players in a back four, one on the right and one on the left. Their first job is the opposing winger. They join attacks with overlapping runs when the center backs and a midfielder can cover the space they leave.
What are the main defensive formations in soccer?
Formations are written from the back, not counting the keeper, so the first number tells you how many defenders there are. The five below run roughly from most defensive to most attacking (teams often shift between two of them in the same game).
5-4-1 formation
Three center backs, two wing backs, a flat midfield four and one striker. With nine players behind the ball, there's very little room between the lines for the other team, and coaches tend to pick it when protecting a lead or facing a stronger opponent. The price is up front, where the lone striker can go ten minutes without a teammate nearby.
4-5-1 formation
A back four with five midfielders in front of it. The extra midfielder makes the center of the field crowded and helps shield the defense. Everything going forward depends on the single striker holding the ball up until help arrives.
5-3-2 formation
Three center backs, two wing backs, three central midfielders and two strikers. The wing backs decide how defensive it really is: when they push up, it plays more like a 3-5-2. With only three in midfield, nobody else covers the flanks, so a tired wing back is the weak spot opponents look for.
4-3-3 formation
A back four, a midfield three and a front three of two wingers and a central striker. It's mainly an attacking shape, but the front three can press high, so defending starts near the other team's goal. Watch the full backs: if the wide forwards don't track back, they end up facing two attackers alone.
4-4-2 formation
Two banks of four with a pair of strikers. It's easy to teach, because every player has a clear partner beside or in front of them, and it leaves few gaps across the width of the field. Our breakdown of 11v11 soccer formations covers more shapes in detail.
How many defenders play in 7v7, 9v9 and 11v11?
Fewer than you might think until age 13. U.S. Soccer's game formats page sets the maximum format at 4v4 for U7 to U8, 7v7 for U9 to U10, 9v9 for U11 to U12 and 11v11 from U13 up. Formations at the smaller sizes are a coach's choice, so the shapes below are common setups rather than rules.
| Format (max age group) | Common back line | What the defenders deal with |
|---|---|---|
| 4v4 (U7 to U8) | No fixed defenders | Everyone attacks and everyone defends |
| 7v7 (U9 to U10) | 2 or 3 (for example 2-3-1 or 3-2-1) | Big spaces behind; keeper plays out from the back |
| 9v9 (U11 to U12) | 3 or 4 (for example 3-2-3 or 3-3-2) | First real full back and center back roles |
| 11v11 (U13+) | 4 or 5, plus keeper | Full formations from the list above |
The small-sided rules shape how young defenders play. When U.S. Soccer rolled out its small-sided standards, it introduced build-out lines starting at U9 (U.S. Soccer, August 2017): a line 14 yards from each goal that the opposing team stays behind when the goalkeeper has the ball in hand or takes a goal kick. Defenders in those age groups get a lot of practice receiving the ball under no pressure and passing out. Leagues apply their own versions, so check yours.
Which defensive position suits my kid?
Positions change a lot before 11v11, so use this as a starting point for a chat with the coach rather than a label. Our post on youth soccer positions covers the whole field.
| If your player... | Try |
|---|---|
| Talks a lot and likes seeing the whole game | Goalkeeper or center back |
| Is calm on the ball and reads passes early | Center back or sweeper |
| Likes running all game and joining attacks | Wing back |
| Enjoys one-on-one duels near the sideline | Full back |
How can a defender practice at home?
Most defending needs an opponent, so a sibling or parent playing attacker is the best home drill there is. Our 1v1 soccer drills work with two people and four cones, and shielding practice needs even less.
The solo work is about the ball coming at you: controlling a bouncing ball, then passing or driving it clear with either foot. That's hard to repeat alone, because every miss means a walk to the fence. The Open Goaaal® 3-in-1 Soccer Goal Trainer combines a goal, a rebounder and a backstop, so the ball comes back to the player. On the Standard size the inner goal is 9 by 5 feet and the backstop is 10 feet tall and up to 21 feet wide. Plan on about 1.5 hours with two people for the first setup.
Soccer defense positions: FAQs
What is the hardest defensive position in soccer?
Ask ten coaches and most will say goalkeeper or center back. A keeper's mistakes are the most visible on the field, and there's usually no one behind to fix them. Center backs make a stream of smaller calls all game, about when to step up, who to pick up and when to leave a runner for a teammate.
What do you call a defender in soccer?
"Defender" or "back" both work. Coaches usually use the position name: center back (or center half), full back, wing back, sweeper. In youth soccer you'll also hear "left back" and "right back" for the full backs.
What makes a good defender?
Mostly positioning, patience and talking. Strong defenders stay goal-side of their player, stay on their feet until the moment to tackle is right, and tell teammates what they see. Speed helps, but reading a pass early beats chasing one.
What is the best defensive formation in soccer?
There isn't one best shape. The 5-4-1 puts the most players behind the ball, which is why teams protecting a lead often switch to it late in games. A 4-4-2 gives up less width. In youth soccer, the best formation is usually the one the players understand.
Final thoughts
Pick the format your child plays, look at how many defenders it uses, and then see which of the five roles fits how they like to play. If they're at 9v9 now, they'll meet full backs and center backs properly for the first time this season, and a few minutes of 1v1 in the backyard each week is a good start.
