*This competition was divided in two phases. In the first phase (34 rounds) three groups were defined of 6 teams each (A, B and C). In the second phase (10 rounds) the teams on each group played against teams of the same group a play-off where the group A competed for the title, group B competed for the right to participate in a triangular with the Cup and the League Champion to dispute the League's Cup (though it was finally not disputed) and group C for the relegation, which initially would correspond to the last three, although during the course of the competicion it was agreed to extend the First Division to 20 teams, so that only the last would descend. Cádiz denounced the change of rules during the competition, it was accepted and finally a triangular was announced between them so that two of them would not descend.
