La Liga 1891 (Argentina)

In 1891, the first season was played in the Primera Liga, the highest football division of Argentina . It is after the English-, Schotse- and North Ierse- the oldest competition in the world.

The competition consisted of five teams played twice against each other. Because Old Caledonians and Saint Andrew's after eight games were similar, they were together champion but a deciding game would determine who could keep the medal.
