S1E3 Soccer Positions Explained: A Guide to Every Player on the Field


Keepers, Defenders, midfielders, and forwards, plus the numbering system commentators use and how formations work
On this episode of Soccer Explained, we broke down the three main position groups on a soccer team, how formations work, and the numbering system people use to talk about players. This post gives you the information in the episode, but the episode itself has a lot more color, stories, and our Pitch Side segment where we share something that caught our eye in the soccer world recently. Give it a listen!
The Starting XI: 11 Players, Three Groups
Every soccer team puts 11 starting players on the field, called the “starting XI.” Yes, it’s always Roman numerals. One of those is the goalkeeper, whose job you can probably guess: keep the ball out of the net. The other 10 players are divided into three groups: defenders, midfielders, and forwards. How many players go in each group is entirely up to the coach. The only hard rule is there must be eleven players, one of whom is a keeper. Coaches get creative with the strategy of who goes in the starting XI and what role they play.
Defenders, a.k.a. “Backs”
You’ll basically always have at least a right back and a left back, with one or more center backs in between. Center backs are typically the big brick-wall types on the team, trying to menace the other team’s offense. Backs play closest to the goalkeeper, and the overwhelming majority of the time their job is exactly what you’d expect: defense. You might also hear the entire defensive group, minus the keeper, called the “back line.”
Midfielders, a.k.a. “Mids”
Midfielders play, predictably, in the middle of the field. And yes, you’ll hear people shorten “midfielder” to just “mid.” (Gen Z readers, this is not an insult). Midfielders have the most varied roles. Their job depends heavily on team strategy. A midfielder can be primarily defensive, primarily offensive, or a mix.
Center midfielders generally hold down the very center of play, flanked by right and left “wingers.” There can also be “defensive midfielders” playing slightly ahead of the backs, and “Attacking midfielders” who will often appear to be forwards. You will also hear the acronyms “CDM” and “CAM,” which stand for “central defensive midfielder” and “central attacking midfielder” respectively.
Forwards, a.k.a. "Strikers"
Forwards, or strikers, are your primary goal scorers, and they play closest to the opposing team’s goal. Along with attacking midfielders, they’re the ones putting the ball in the net or delivering assists (assists in soccer are the same as in basketball/hockey: passing to the player who scores). Because gameplay in soccer is so fluid, any player can score, but it’s usually the forwards and attacking midfielders who do.
Formations: What Those Three Numbers Mean
When you hear a commentator or read that a team is playing a “4-4-2,” that’s called a formation. The three numbers tell you how the ten outfield players (everyone but the keeper) are arranged: defense, midfield, and forwards. So 4-4-2 means four defenders, four midfielders, and two forwards. A 3-5-2 formation means three defenders, five midfielders, and two forwards. The numbers always add up to 10 because the goalkeeper is assumed and not included in the formation.
Formations describe a team’s general strategy and where players start on the field, but there’s a lot of movement. Players don’t rigidly stick to their spots. As we put it on the show: imagine how fluid positions are in basketball or hockey, then multiply it by a playing field four times the size with double the number of players. That gives you a sense of the fluidity of soccer positions.
The Position Numbering System
If you follow baseball, you’re familiar with a system of numbering the players’ positions. Soccer has its own version of this, but with important caveats. Each position is traditionally assigned a number from 1 to 11, and commentators or analysts refer to them all the time. The catch is these numbers are based on formations that were popular in old-school British football, so they don’t necessarily match what’s happening on the field today. But they’re still how people reference positions, so knowing them helps you follow along.
Here’s the traditional breakdown:
#1 – Goalkeeper
#2 & #3 – Right Back & Left Back
#4 & #5 – Center Backs
#6 – Defensive Midfielder
#7 – Right Winger
#8 – Center Midfielder
#9 – Striker
#10 – Attacking Midfielder
#11 – Left Winger
A team’s number 1 is always their goal keeper, even today. And numbers 2 and 3 are always the right and left back. But things can get muddled from there. And you may have noticed 7, 8, and 11 are the three players traditionally across the center of the midfield. It doesn’t make sequential sense, but that’s tradition for you.
The Romantic Number 10
The number 10 holds a special place in soccer culture. Number 10s are the creative playmakers. The ones who score goals, rack up assists, and make something out of nothing. Many of the most legendary players in history played in that role, and number 10s tend to get the most attention and recognition. So it’s often the position kids in soccer dream of playing.
The Numbers on Lineup Cards
When coaches submit their starting XI to the refs, they still assign these traditional numbers, always moving from back to front, starting with the keeper. Lower numbers near their own goal, and higher numbers near the opponent’s. But whether a player’s assigned number on the lineup card actually matches the traditional position number is less guaranteed these days. The important thing is that when a commentator refers to “a number 6,” they’re talking about someone playing a defensive midfield role, regardless of their number in the starting XI.
