Football positions explained: every role on the pitch
A clear guide to the positions in football — goalkeeper, defenders, midfielders and forwards — plus how formation numbers like 4-3-3 describe a team's shape.
The four lines of a team
Almost every football team is built from four groups: the goalkeeper, the defenders, the midfielders and the forwards. From back to front, each line has its own job — stop goals, win and use the ball, create and score. A team's formation simply describes how many players sit in each line. Understanding these four bands is the foundation for reading any match, because everything a side does flows from how it fills them.
Defenders
The back line is usually built from centre-backs and full-backs. Centre-backs are the central defenders, tasked with marking strikers, heading clear and organising the line. Full-backs play on the flanks; historically defensive, the modern full-back also races forward to support attacks and deliver crosses. Some systems use three central defenders instead of two, with wing-backs pushed high on either side to cover the whole flank.
Midfielders
Midfield is the engine room, and it splits into roles. The defensive midfielder — the number 6 — screens the back four and breaks up attacks. Central midfielders link defence and attack, covering huge distances. The attacking midfielder — the number 10 — operates between the lines to create chances. A team rarely uses all three at once; the balance of holders and creators defines how it plays.
Forwards
The front line carries the goal threat. The central striker — the number 9 — leads the line, finishing chances and occupying defenders. Wingers hug the touchlines, using pace and dribbling to beat full-backs and supply crosses or cut inside to shoot. Modern forwards are fluid: wingers drift central, strikers drop deep, and the old fixed positions blur into interchanging roles.
Reading a formation
Formations are written from defence forward, so 4-3-3 means four defenders, three midfielders and three forwards; 4-4-2 means four, four and two. The goalkeeper is assumed and never counted. The numbers describe a starting shape, not a rigid cage — teams shift between an attacking and defensive shape constantly. But knowing the basic template tells you at a glance how a side intends to balance solidity and attack.
