Clean sheet

A clean sheet is a football term, meaning a game in which the team referred to have not conceded any goals. The main purpose of goalkeepers and defenders is to keep a clean sheet.
Example: Team A beats Team B 3-0, so Team A are said to have "kept a clean sheet," as they have not conceded any goals.
The equivalent term in American English is shutout; however the standard term used for international and club competitions around the world when no goals are conceded is a clean sheet.
Origin of Term
The term first appeared in the 1930s and derived from sports reporting in which the reporter would use separate pieces of paper to record different events of the game. If one team did not let in a goal, then that team's "details of goals conceded" column would be left blank, hence resulting in a 'clean sheet'.
Fantasy Football
In many Fantasy Football competitions, defenders and goalkeepers get awarded points for keeping a clean sheet.
