Premiership (Tierrador)

The Primera Liga de TFF, commonly known simply as Primera Liga in Tierrador, and as Premier League in English-speaking countries and officially as Primera Liga presented by Banco Auqali for sponsorship reasons, stylized as Primera Liga, is the men's top professional football division of the Tierradorian football league system. Administered by the Liga Nacional de Fútbol, it is contested by 20 teams, with the three lowest-placed teams at the end of each season being relegated to the Campeonato LNF and replaced by the top two teams and a play-off winner in that division.

Competition format
Primera Liga's competition format follows a round-robin format. The season usually takes place from August to May, with matches being played on Fridays, Saturdays and Mondays. Member clubs play each other twice, once home and the other away, for a total of 38 matches, over a total of 40 weeks (each club receives two off-weeks). Clubs receive 3 points for victories, 1 point for a draw, and no points for losses. For the 2005–06 season only, 1 point was deducted for every loss that a club received. This resulted in Cuervos C.F. winning the Primera Liga for the first time in club history, despite having an overall record of 23–13–2, where they would've had 82 points, but since they lost 2 matches, their point total was reduced to 80 points. Cuervos finished on top of Olímpico de Taisgol, who finished with a record of 24–10–4, where they also would have had 82 points, but would still finish above Cuervos due to Olímpico having 1 more win, however because Olímpico lost 4 matches in the season, their point total was reduced to 78 points, therefore placing them at second place. Because of this, and with strong protest from Olímpico and Internacional de Auqali, the point deduction system was eventually abandoned in June 2006.
