Association football, more commonly known as football or soccer
A place where soccer is played, that is, association football, more commonly known as football or soccer, a team sport played between two teams of eleven players (on Wikipedia).
Note: While called "football" (fussball, fotball, ...) in many countries, it is best to tag it as "soccer" to avoid confusion with other usages of "football". The OpenStreetMap tagging guidelines have always been to go for UK-English spellings. However, in this special case it is far too confusing for some other English speaking countries, and it has been decided to use soccer to mean this kind of football.
