In team sport, team of the century and team of the decade are hypothetical best teams over a given time period. For the century team, it can be either 100 years, or for a century (always the 20th). Similarly the team of the decade can be for 10 years or a decade (for example the 1980s). Teams of the decade and century are selected for both leagues and clubs and sometimes selected for other reasons, such as to honour the contribution of a particular ethnic group.
