The starting whistle
New to football or brushing up? Start with six essentials, explained in plain English.
A team can have up to 11 players on the field, including one goalkeeper. Substitution limits depend on the competition. Youth and grassroots formats may use smaller teams.
Read IFAB Law 3 ↗A standard match has two 45-minute halves. The referee adds time for stoppages such as injuries and substitutions. Added time is different from extra time used in some knockout matches.
Read IFAB Law 7 ↗Being in an offside position alone is not an offence. In the opponents’ half, a player is generally in that position when nearer the goal line than both the ball and second-last opponent as a team-mate plays the ball. Active involvement matters.
See the full rule & exceptions ↗A yellow card is a caution; a red card sends a player off. A second caution in the same match also results in a sending-off. The seriousness of a challenge affects the referee’s decision.
Read IFAB Law 12 ↗Look beyond the ball. Notice who stays wide, who runs behind the defence and who offers a safe passing option. Those movements often explain how a chance is created.

Read the game
Protects the goal, organises the defence and starts attacks with distribution.
Defends central areas, challenges attackers and helps build from the back.
Covers wide areas and may push forward to support attacks and deliver crosses.
Connects defence and attack. Some shield the back line; others create chances.
Stretches the pitch, takes on defenders and supplies crosses or cuts inside.
Leads the attack, finds scoring positions and can link play or press defenders.
Three formations to recognise
Four defenders, three midfielders and three forwards. Wide attackers can stretch the opposition while the midfield supports possession and pressing.
Two deeper midfielders sit behind an attacking trio and one striker. The pair can protect the defence while the players ahead create chances.
Three centre-backs, five midfield players including wing-backs, and two forwards. Wing-backs often drop deeper when the team defends.
Formation numbers count outfield players only. They are a starting shape: roles and positions change with the ball, the opponent and the coach’s plan.

Good questions
No. Position is judged when a team-mate plays or touches the ball, and the ball’s position matters too. A player must become actively involved to be penalised. There is no offside offence when receiving the ball directly from a goal kick, throw-in or corner kick. IFAB Law 11 explains the exceptions.
Added time compensates for time lost during each half. The board displays a minimum, so the referee may allow more. Extra time is a separate period used by some competitions to resolve a drawn knockout match. Check that competition’s rules for the tie-breaking procedure.
Pick one team for a few minutes. Watch its shape without the ball, how its midfield offers passing options and whether its full-backs push forward. Compare the shape before and after possession changes. You do not need to follow every player at once.
