"A single-elimination tournament - also called an Olympic system tournament, a knockout, single penetration, or sudden death tournament - is a type of elimination tournament where the loser of each bracket is immediately eliminated from winning the championship or first prize in the event.
This does not always mean that the defeated competitor will not participate further in the tournament; in some such tournaments, consolation or "classification" contests are subsequently held among those already defeated to determine the awarding of lesser places, for example, a third place playoff.
Where more than two competitors can play in each match, such as in a shootout poker tournament, players are removed when they can no longer play until one player remains from the group. This player moves on to the next round.
A simple way to describe a single-elimination tournament is that the winner of each match moves on and the loser fails to progress in the tournament.
Some competitions are held with a pure single-elimination tournament system. Others have many phases, with the last being a single-elimination final stage called playoffs." [Single-elimination tournament. Wikipedia]

"Gameplay.
Association football is played in accordance with a set of rules known as the Laws of the Game. The game is played using a spherical ball (of 71 cm (28 in) circumference in FIFA play), known as the football (or soccer ball). Two teams of eleven players each compete to get the ball into the other team's goal (between the posts and under the bar), thereby scoring a goal. The team that has scored more goals at the end of the game is the winner; if both teams have scored an equal number of goals then the game is a draw. Each team is led by a captain who has only one official responsibility as mandated by the Laws of the Game: to be involved in the coin toss prior to kick-off or penalty kicks.
The primary law is that players other than goalkeepers may not deliberately handle the ball with their hands or arms during play, though they do use their hands during a throw-in restart. Although players usually use their feet to move the ball around, they may use any part of their body (notably, "heading" with the forehead) other than their hands or arms. Within normal play, all players are free to play the ball in any direction and move throughout the pitch, though the ball cannot be received in an offside position." [Association football. Wikipedia]

"In association football, the formation describes how the players in a team are positioned on the pitch. Different formations can be used depending on whether a team wishes to play more attacking or defensive football. ...
The 4–3–3 was a development of the 4–2–4, and was played by the Brazilian national team in the 1962 World Cup. The extra player in midfield allows a stronger defence, and the midfield could be staggered for different effects. The three midfielders normally play closely together to protect the defence, and move laterally across the field as a coordinated unit. The three forwards split across the field to spread the attack, and may be expected to mark the opposition full-backs as opposed to doubling back to assist their own full-backs, as do the wide midfielders in a 4–4–2. When used from the start of a game, this formation is widely regarded as encouraging expansive play, and should not be confused with the practice of modifying a 4–4–2 by bringing on an extra forward to replace a midfield player when behind in the latter stages of a game. This formation is suited for a short passing game and useful for ball retention.
A staggered 4–3–3 involving a defensive midfielder (usually numbered four or six) and two attacking midfielders (numbered eight and ten) was commonplace in Italy, Argentina, and Uruguay during the 1960s and 1970s. The Italian variety of 4–3–3 was simply a modification of WM, by converting one of the two wing-halves to a libero (sweeper), whereas the Argentine and Uruguayan formations were derived from 2–3–5 and retained the notional attacking centre-half. The national team which made this famous was the Dutch team of the 1974 and 1978 World Cups, even though the team won neither." [Formation (association football). Wikipedia]

4–4–2.
This formation was the most common in football in the 1990s and early 2000s, so well known that it has even inspired a magazine title, FourFourTwo. The midfielders are required to work hard to support both the defence and the attack: typically one of the central midfielders is expected to go upfield as often as possible to support the forward pair, while the other will play a "holding role", shielding the defence; the two wide midfield players must move up the flanks to the goal line in attacks and yet also protect the fullback wide defenders."

"In the sport of association football, each of the eleven players on a team is assigned to a particular position on the field of play. A team is made up of one goalkeeper and ten outfield players who fill various defensive, midfield and attacking positions depending on the formation deployed. These positions describe both the player's main role and their area of operation on the pitch. ...
Goalkeeper is the most defensive position in football. The goalkeeper's main job is to stop the other team from scoring by catching, palming or punching the ball from shots, headers and crosses. ...
Defenders play behind the midfielders and their primary responsibility is to provide support to the team and to prevent the opposition from scoring a goal. They usually remain in the half of the field that contains the goal they are defending. Taller defenders will move forward to the opposing team's penalty box when their team takes corner kicks or free kicks, where scoring with one's head is a possibility. ...
Midfielders (originally called half-backs) are players whose position of play is midway between the attacking forwards and the defenders. Their main duties are to maintain possession of the ball, taking the ball from defenders and feeding it to the strikers, as well as dispossessing opposing players. ...
Forwards (or strikers) are the players who are positioned nearest to the opposing team's goal. The primary responsibility of forwards is to score goals and to create scoring chances for other players." [Association football positions. Wikipedia]
