What Is Football and Why Does the World Love It?
Football — called soccer in the United States, Canada, and Australia — is the world's most popular sport by virtually every measure. Over 5 billion people watched the 2022 FIFA World Cup in Qatar. More than 250 million people play the game regularly across every continent. The sport is governed by FIFA (Fédération Internationale de Football Association), which has more member nations than the United Nations.
The reason for football's global dominance is its simplicity at the core level. You need a ball and something to aim at. Children in Cambodia, Brazil, Nigeria, and Norway grow up kicking footballs against walls, through makeshift goals, in bare feet. The rules are learnable in an afternoon. The game is free to play. Yet at the highest level, football involves tactical depth, physical excellence, and moments of individual brilliance that make it endlessly compelling to watch — whether you are a first-time viewer or a lifelong fan.
The sport has two distinct terminologies depending on where you are in the world. "Football" is the term used everywhere in Europe, Africa, Asia, and South America. "Soccer" is used in the United States, Canada, Australia, and a few other countries where a different sport also uses the word "football." Both words refer to exactly the same game. In this guide, we use football and soccer interchangeably.
In Southeast Asia, football holds a special place. The English Premier League is broadcast live across Cambodia, Thailand, Vietnam, and Indonesia, and cafes fill up at 2am local time for Champions League matches. The ASEAN Football Federation Championship — the regional's own tournament — draws enormous crowds and passionate support for national teams. For millions of people across the region, football is not just a sport but a shared language and a weekly ritual.
The 8 Core Rules Every Beginner Must Know
Football has 17 official Laws of the Game set by IFAB (International Football Association Board). These are the eight that matter most when you start watching.
2
The Pitch
A rectangular grass (or artificial turf) field, typically 100–110 metres long and 64–75 metres wide for professional matches. The pitch is divided into two halves, with a centre circle, penalty areas at each end, and goal areas inside them.
3
Players and Substitutions
Each team fields 11 players including the goalkeeper. Up to 5 substitutions are allowed per match in most competitions. A substituted player cannot return. If a team is reduced to fewer than 7 players (due to red cards), the match is abandoned.
4
Fouls and Free Kicks
A foul is any illegal action: tripping, pushing, charging, or dangerous tackles. Most fouls result in a direct free kick from the spot of the offence. Handball (touching the ball with the hand or arm) is also a foul in most situations. Fouls inside the penalty area result in a penalty kick.
5
Throw-Ins, Corner Kicks, Goal Kicks
When the ball goes out of play over a sideline, the opposing team takes a throw-in. When the ball crosses the end line last touched by the defending team, the attacking team gets a corner kick. When the attacking team last touches it over the end line, the defending team takes a goal kick.
6
Offside
A player cannot receive the ball while in an offside position — nearer to the opponent's goal than both the ball and the second-to-last defender. They must be level with or behind these reference points when the ball is played. Being offside at the moment the ball arrives is not an offence — the moment of the pass matters.
7
Yellow and Red Cards
A yellow card is a caution. Two yellows in the same match equal a red. A straight red is given for serious foul play, violent conduct, or denying an obvious goal-scoring opportunity. A red-carded player must leave immediately and cannot be replaced — their team plays with 10 men.
8
Penalty Kicks
Awarded when a defending player commits a foul or handball inside their own penalty area. Taken from 11 metres in front of the goal, with only the goalkeeper to beat. All other players must stay outside the penalty area until the kick is taken.
Note on VAR (Video Assistant Referee): VAR is a technology used in top leagues to review match-changing decisions — goals, penalty kicks, red cards, and mistaken identity. A VAR team watches video replays in an offsite room and alerts the on-field referee if a clear and obvious error has been made. Controversial but now standard in the Premier League, Champions League, and most major competitions worldwide.
Football Positions Explained
Each team fields 11 players with specific roles. Understanding what each position does transforms how you watch a match — suddenly the movement makes sense.
Reading a team lineup: positions are listed from back to front — e.g. 4-3-3 = 4 defenders · 3 midfielders · 3 forwards
GK
Goalkeeper
Last line of defence
The only player allowed to handle the ball with their hands (inside the penalty area only). Responsible for saving shots, commanding the penalty area, and distributing the ball to start attacks. Modern goalkeepers must be comfortable playing with their feet.
World-class examples: Alisson Becker, Manuel Neuer, Thibaut Courtois
CB
Centre-Back
Central defender
Positioned in the centre of defence, the centre-back's job is to stop the opposing forwards, win headers from crosses, and prevent shots on goal. Teams typically play with two or three centre-backs. They need to be strong in the air, good at tackling, and calm under pressure.
World-class examples: Virgil van Dijk, Rúben Dias, Marquinhos
LB/RB
Full-Back
Wide defender
Left-backs (LB) and right-backs (RB) defend the wide channels on each side of the pitch. In the modern game, full-backs are expected to bomb forward to support attacks, delivering crosses into the box and overlapping with wingers. They need stamina, pace, and the ability to attack and defend.
World-class examples: Trent Alexander-Arnold, Achraf Hakimi, Andrew Robertson
CDM
Defensive Midfielder
Midfield anchor
Sits in front of the back four and acts as a shield for the defence. The CDM breaks up opposition attacks, wins the ball back quickly, and recycles possession simply. Not expected to score, but must be disciplined and positionally excellent. Often the most underappreciated player on the pitch.
World-class examples: Rodri, Casemiro, N'Golo Kanté
CM
Central Midfielder
Engine room
The all-round midfielder who covers the most ground in a match. Box-to-box midfielders work both ends of the pitch — winning the ball defensively and arriving late in the box to score or assist. Technical midfielders (playmakers) focus on controlling the tempo, finding passes, and dictating the rhythm of the game.
World-class examples: Luka Modrić, Kevin De Bruyne, Pedri
LW/RW
Winger
Wide attacker
Plays on the left or right flank and is typically the team's most exciting attacking player. Wingers use pace and dribbling to beat defenders, then either cross the ball into the box or cut inside to shoot. Modern "inverted wingers" — a right-footed player on the left, or vice versa — cut inside onto their stronger foot to shoot at goal.
World-class examples: Mohamed Salah, Vinicius Jr., Bukayo Saka
CAM
Attacking Midfielder
Number 10, creator
The most creative player in the team, the CAM operates in the space between the opposition midfield and defence. Their job is to find pockets of space, play through-balls to forwards, score from distance, and generally be the most technically gifted player on the pitch. The "number 10" shirt is traditionally reserved for this role.
World-class examples: Martin Ødegaard, Bruno Fernandes, Paulo Dybala
ST
Striker / Centre-Forward
Goal scorer
The team's primary goal scorer, positioned furthest up the pitch. The striker's job is simple in concept and brutally difficult in execution: get into scoring positions and put the ball in the net. Different striker types exist — the powerful target man who holds the ball up, the pacey runner who chases in behind, and the technical false 9 who drops deep to create.
World-class examples: Erling Haaland, Harry Kane, Robert Lewandowski
How to Read a Team's Lineup
When you see a team described as playing "4-3-3," the numbers refer to the number of players in each line from back to front: 4 defenders, 3 midfielders, 3 forwards. The goalkeeper is always assumed and not counted in the formation number. So a 4-3-3 has 4 + 3 + 3 + 1 (GK) = 11 players total.
Formation numbers are a rough guide — the actual shape of a team changes constantly during a match. A team listed as 4-3-3 may look like a 4-5-1 when defending (the two wide forwards drop back) and a 2-3-5 when attacking aggressively. Understanding that formations are fluid, not fixed, is one of the most important conceptual leaps for beginner football watchers.
The 5 Most Common Formations — Decoded
A formation is the tactical blueprint a manager chooses to organise their team on the pitch. Different formations suit different styles of play — some prioritise attack, others are built to be defensively solid, and others look to control possession in midfield. The same manager will often change formations between matches depending on the opposition.
When watching a match, you can usually identify the formation within the first few minutes by watching where the players position themselves when their team is out of possession — that is when the defensive shape becomes clearest.
4-3-3
Attacking / BalancedFour defenders, three midfielders, three forwards. The most widely used modern formation. Balanced in defence and attack, with wingers providing width and the three midfielders covering the centre of the pitch. Used by Liverpool, Barcelona, and many national teams.
4-4-2
Traditional / BalancedThe classic formation — four defenders, four midfielders, two strikers. Dominated football from the 1960s to the 2000s. Provides balance and simplicity, with two strikers working in partnership. Less common at the top level today but still used widely in lower leagues and international football.
4-2-3-1
Structured / CreativeFour defenders, two defensive midfielders, three attacking midfielders, one striker. The two defensive midfielders (double pivot) protect the back four while the three behind the striker create. Common in European football and international tournaments. Real Madrid and Germany have famously used this shape.
3-5-2
Defensive / Wing-Back ReliantThree centre-backs, five midfielders (including two wing-backs who act as wide defenders and attackers), two strikers. Wing-backs are the key — they must cover the full length of the pitch. Provides defensive solidity with the three-CB base while creating overloads in midfield.
5-3-2
Defensive / Counter-AttackFive defenders (three CBs and two wing-backs who sit deeper than in 3-5-2), three midfielders, two strikers. A compact, defensive formation used by teams who want to be hard to beat and hit on the counter-attack. Common in knockout football and for teams facing stronger opposition.
How to Watch a Football Match as a Beginner
Watching football for the first time can be confusing. The ball moves quickly, the camera often pulls back to show a wide tactical picture, and commentators assume you already understand the context. Here is how to approach your first few matches so you actually enjoy them rather than feeling lost.
1. Pick One Team to Follow
Watching football without a team to support is like watching a film with no protagonist. Pick a team — ideally one you have some connection to (geography, a friend who supports them, a player you find interesting) — and follow them specifically. When you watch a match, focus entirely on your team's movements, not both teams at once. Watch where their defenders position themselves when defending. Watch how their midfielders receive the ball and move it. Watch how their forwards create space. Over a few matches, patterns become visible and the game clicks into place.
2. Watch the Off-Ball Movement
Most TV broadcasts follow the ball. But the most interesting things in football happen away from the ball — a striker making a run into space, a defender stepping up to play someone offside, a midfielder dropping into a gap to receive. When the camera is on the player with the ball, try to notice the players nearby: are they calling for the ball? Moving into space? Blocking a passing lane? This off-ball reading is what separates casual viewers from those who truly understand the game. It takes around 10 to 15 matches before it becomes natural.
3. The Tactical Phases of Play
A football match has four recurring phases that alternate constantly:
In Possession
Your team has the ball. The goal is to move it forward, create opportunities, and eventually score.
Out of Possession
The opposition has the ball. Your team either presses to win it back quickly or drops into a defensive shape.
Transition Attack
Your team just won the ball. The next few seconds are a window to attack before the opposition reorganises.
Transition Defence
Your team just lost the ball. Everyone must quickly get into a defensive position to prevent a counter-attack.
4. Where to Watch Football in Asia
Across Southeast Asia, the English Premier League is the most widely broadcast competition. Major matches are shown on dedicated sports channels and streaming platforms available across Cambodia, Thailand, Vietnam, Indonesia, and the Philippines. The UEFA Champions League — Europe's elite club competition featuring the best teams from all European leagues — is typically broadcast on Tuesday and Wednesday nights (Cambodia time: roughly 2:45am and 3:00am for 21:00 CET kick-offs). For local fans, the easiest entry point is watching a Premier League match at a sports cafe — the atmosphere, the crowd reactions, and the commentary from the people around you will teach you more about the game in 90 minutes than any guide can.
The AFF Championship (ASEAN Football Federation Championship) is the regional tournament where Cambodia, Vietnam, Thailand, Indonesia, Malaysia, Myanmar, and other Southeast Asian nations compete. Matches are held every two years and broadcast freely across the region. Supporting your national team in the AFF Championship is often the most emotionally engaging way to fall in love with football.

Football FAQ for Beginners
QWhat is the offside rule in football?
The offside rule is one of the most misunderstood rules in football. A player is offside if they are in the opponent's half and are closer to the opponent's goal line than both the ball and the second-to-last defender at the moment the ball is played to them. Simply being in an offside position is not an offence — a player is only penalised if they become actively involved in play. If offside is called, the opposing team gets a free kick from where the offside player was standing. VAR is now used in top leagues to check borderline offside calls, sometimes drawing lines to within millimetres.
QHow long is a football match?
A standard professional football match consists of two halves of 45 minutes each, totalling 90 minutes of regulation time. After each half, the referee adds stoppage time to compensate for time lost due to injuries, substitutions, and VAR checks — often 3 to 10 minutes per half. In knockout competitions, if the score is level after 90 minutes, the game proceeds to 30 minutes of extra time (two 15-minute halves). If still tied, a penalty shootout decides the winner.
QWhat does a goalkeeper do in football?
The goalkeeper is the only player allowed to handle the ball with their hands, and only within their own penalty area. Their primary job is to prevent the opposing team from scoring by saving shots, catching crosses, and commanding their penalty area. Modern goalkeepers are also expected to be excellent with their feet — they regularly receive back-passes from defenders and distribute the ball accurately to start attacks. Top goalkeepers like Alisson Becker and Manuel Neuer have redefined the position as a sweeper-keeper who acts as an eleventh outfield player.
QWhat is the difference between a yellow card and a red card?
A yellow card is a formal caution — the player is warned but stays on the pitch. Two yellow cards in the same match automatically equal a red card. A straight red can be given for serious foul play, violent conduct, deliberate handball to deny a clear goal, or serious verbal abuse. When a player is sent off, their team continues with 10 players and cannot bring on a replacement. Red-carded players also serve a ban for subsequent matches.
QWhat are the most popular football leagues in the world?
The most widely followed leagues are the English Premier League (EPL), La Liga in Spain, the Bundesliga in Germany, Serie A in Italy, and Ligue 1 in France — collectively known as the "Big Five" European leagues. For international football, the FIFA World Cup (every four years) is the single most-watched sporting event on earth. In Southeast Asia, the AFC Champions League covers Asian club football, and the AFF Championship is the regional international tournament.
QWhat is a penalty kick and when is it awarded?
A penalty kick is awarded when a defending player commits a foul or handball inside their own penalty area. The kick is taken from 11 metres in front of the goal, with only the goalkeeper to beat. All other players must stay outside the penalty area until the kick is taken. Penalties are scored roughly 75-80% of the time in professional football. In a penalty shootout, each team takes five kicks alternately, and the team scoring more wins.
QHow do football substitutions work?
Each team is allowed up to five substitutions during a match, with a maximum of three stoppages in play to make those changes (plus half-time). A substituted player cannot return. Substitutions are a key tactical tool — managers use them to introduce fresh energy, change the team's shape, or replace an injured player. The five-substitution rule was made permanent after the COVID-19 pandemic.
QIs football popular in Cambodia and Southeast Asia?
Football is extremely popular across Southeast Asia. The English Premier League, La Liga, and Champions League are broadcast live across Cambodia, Thailand, Vietnam, and Indonesia, and cafes fill for major matches. Cambodia competes in the Cambodian Premier League domestically and in FIFA World Cup qualifying and the AFF Championship internationally. Vietnam has been the dominant Southeast Asian football nation recently, winning the AFF Championship multiple times.
