National Association for Football

National Association for Football (NAF; 曾國足球協會), or Tseng Football Association is the main professional soccer league in the Tseng Republic, currently compromising of 30 teams. Its title, the Jorge Ka Championship Trophy, is the oldest professional sport trophy in Tseng and is awarded to the league champion at the end of each season.

History
The NAF's predecessor was the National Football League (NFL), which existed from 1953 to 1960. In the late 1950s, the NFL was riddled by corruption scandals involving the Bank of Tseng and the National Prosperity Party, in which players, coaches, and staff would get monetary compensation for being a member of the NPP and/or "spying" on opposing teams' players/personnel in order to rat out communists. Some teams were against this, and decided to start a new league.

The NAF was founded on February 29, 1960, in the coastal town of Longtan, Tseng City-Capital, in a meeting by representatives of Hillsbourgh FC, Queens FC, and Sandao Islanders, members of the NFL.

Season
The season runs from May to December, playoffs included. Each team plays 40 games. 16 teams (4 from each division) make the playoffs and they face in a group and knockout format.
