The current season is the most narrow in the century. Last year, in the same matchweek, the difference between the first and the sixth was 10 points
Barça's loss against Betis and the victories of Sevilla, Atlético, Alavés and Real Madrid make the league table even more narrow. Barça is the leader with 24 points in LaLiga standings and they just lead the sixth, Real Madrid, for four points. It meant that is the most competitive season of the century.
There were years when Barça and Madrid win all their matches and it was usual to see them ahead with 10 or more points of difference. However, the current season is mad. Every team can lose or win, it is unexpected. Last year, at the same 12 matchweek, the leader was 10 points ahead the sixth. Now, teams like Alavés or Espanyol can face the giants like Barça, Sevilla or Madrid and are in the same fight for the title.
