In association football, the manager is the person who has overall responsibility for the running of a football team. They have wide-ranging responsibilities, including selecting the team, choosing the tactics, recruiting and transferring players, negotiating player contracts, and speaking to the media. In professional football, a manager is usually appointed by and answerable to the club's board of directors, but at an amateur level the manager may have total responsibility for the running of a club.
