A football team is a group of players selected to play together in the various team sports known as football. Such teams could be selected to play in a match against an opposing team, to represent a football club, group, state or nation, an all-star team or even selected as a hypothetical team (such as a dream team or team of the century) and never play an actual match.
The difference between a football team and a football club is incorporation, a football club is an entity which is formed and governed by a committee and has members which may consist of supporters in addition to players. The benefit of club formation is that it gives teams access to additional volunteer or paid support staff, facilities and equipment.
