Reserve teams usually consist of a combination of emerging youth players and first-team squad players. These teams are distinct from a club's youth team, which usually consists of players under a certain age and plays in an age-specific league. In England, Argentina and the United States the term reserve is commonly used to describe these teams.[citation needed] In Germany and Austria the terms Amateure or II is used, while B team is used in the Spanish football league system, the Czech Republic, Slovakia, and Portugal.
