Football is the most watched sport in the world, and in Bangladesh the excitement around the World Cup, the Premier League and the national team grows every year. Yet many new fans enjoy the matches without fully understanding why a goal is ruled out, why a player is booked or why the referee lets play continue after a foul. This guide explains the core rules in plain language so you can follow every match with confidence.

The basics: teams, time and the ball

Each team has eleven players on the pitch, including one goalkeeper. A match lasts ninety minutes, split into two halves of forty-five minutes, plus stoppage time added by the referee for injuries, substitutions and other delays. In knockout matches, extra time of two fifteen-minute halves and then a penalty shoot-out can decide the winner. A goal counts only when the whole ball crosses the whole goal line between the posts and under the crossbar.

Offside in simple words

Offside confuses more fans than any other rule. A player is in an offside position if, when a teammate passes the ball forward, they are nearer to the opponent's goal line than both the ball and the second-last defender (usually the last outfield defender, since the goalkeeper is normally the last). Being in that position is not an offence by itself. It becomes an offence only if the player gets involved in play, for example by receiving the ball or blocking the goalkeeper's view. A player cannot be offside in their own half or directly from a throw-in, goal kick or corner.

Fouls, free kicks and penalties

A foul is any unfair action such as tripping, pushing, holding or a careless tackle. The fouled team receives a free kick from the spot of the offence. If a defender commits a foul inside their own penalty area, the attacking team gets a penalty kick from twelve yards. The referee can also play "advantage" and let the game continue if stopping it would help the team that committed the foul.

Yellow and red cards

Yellow card: a caution for things like reckless tackles, time-wasting or arguing with the referee.
Second yellow: the player is sent off and cannot be replaced.
Straight red: for serious foul play, violent conduct or denying a clear goal-scoring chance by a foul.

Handball

Handball is an offence when a player deliberately touches the ball with their hand or arm, or when their arm makes their body unnaturally bigger. Accidental contact with an arm close to the body is usually not penalised. Any goal scored directly from an attacker's hand or arm, even accidentally, is disallowed.

Video assistant referee (VAR)

In major competitions, VAR reviews four types of decisions: goals, penalties, direct red cards and mistaken identity. The video team does not re-referee the whole match; it steps in only for clear and obvious errors or serious missed incidents. That is why some close calls are checked for a long time while others are not reviewed at all.

Substitutions and squad rules

Most top competitions now allow five substitutions per team in normal time, made in up to three stoppages plus half-time. Some tournaments allow an extra substitution in extra time and additional concussion substitutes. Once a player is substituted, they cannot return to the match.

Why rules shape history

Rule changes have changed football itself. The back-pass rule of the early 1990s sped up the game, and VAR has changed how penalties are given. Those changes are part of why some historic marks are so hard to repeat today, as explained in this feature on football records that may never be broken.

Final thoughts

Once you understand offside, fouls, cards, handball and VAR, matches become far more enjoyable. You start to see why a manager is angry on the touchline, why a striker stays level with the last defender and why the crowd holds its breath during a review. Watch your next match with these rules in mind and you will notice how much more of the game makes sense.
