Soccer (Football) Positions

"The goal line is the chalked or painted line dividing the end zone from the field of play in American football and Canadian football. It is the line that must be crossed in order to score a touchdown
If any part of the ball reaches any part of the imaginary vertical plane transected by this line while in-bounds and in possession of a player whose team is striving toward that end of the field, this is considered a touchdown and scores six points for the team whose player has advanced the ball to, or recovered the ball in, this position. This is in contrast with other sports like Association football and ice hockey, which require the puck or ball to pass completely over the goal line to count as a score.
If any member of the offensive team is downed while in possession of the ball behind his own team's goal line, this is called a safety and scores two points for the defensive team.
If, during the course of play, a loose ball travels past the goal line and is recovered within the end zone, then it is a touchdown if recovered by the kicking team, or a touchback if recovered and downed by the receiving team.
In the event of a kick recovered in one's own end zone, the entirety of the ball must pass the goal line in order for the ball to be considered in the field of play, and not a touchback." [Goal line (gridiron football). Wikipedia]

"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]
