Full-back
A full-back is a defender who plays on the left or right side of the defence, defending the flank while also supporting attacks down the wing.
Overview
Full-backs (left-back and right-back) start wide in the defensive line. Defensively they mark opposing wingers and prevent crosses; in attack they overlap to add width and deliver balls into the box.
The role has become increasingly two-way in modern football, so full-backs often cover more distance than any other outfield position.
Responsibilities
- Marks and contains opposing wingers on their side.
- Blocks or intercepts crosses from the flank.
- Overlaps into attack to provide width and crossing options.
- Recovers quickly to defend against counter-attacks.
- Links play between defence and midfield down the wing.

Player roles
- SweeperA covering defender who plays behind the main defensive line, free of a fixed marking job, to read danger and clean up attacks that slip past teammates.
- Utility playerA dependable, versatile player who can competently fill several different positions as the team needs, rather than specialising in just one.
- PlaymakerThe playmaker is a team's creative hub — the player who orchestrates attacks, controls the tempo and distributes the ball so teammates can score.
- Last line of defenceThe final barrier between an attack and a score — the goalkeeper, sweeper or last-ditch defender whose job is to stop what the rest of the team has let through.
- All-RounderAn all-rounder is a versatile player who contributes across attack and defence rather than specialising in a single phase, position, or skill.
Tactics
- Wing playAttacking down the flanks and crossing the ball into the box to stretch the defence and create chances.
- Counter-attackWinning the ball and moving forward at speed to attack before the opponent can reorganise their defence.
- High pressA football tactic where a team hunts the ball high up the pitch to win it back close to the opponent’s goal.
- Offside trapA defensive football tactic where the back line steps up together to leave an attacker offside.
- Zone defenceA defensive system where each player guards an area of the court rather than a specific opponent.
Strategies
- Using Width and SpaceA side's plan to stretch the playing area and open gaps when attacking, then shrink and control that space when defending.
- Zone vs Man MarkingTwo defensive systems compared: zonal marking guards areas of the field, while man-to-man marking assigns each defender a specific opponent to track.
- Building momentumMomentum is the sense that a contest is flowing one side's way — building it means stacking positive plays while working to interrupt an opponent's run.
