Real Madrid have missed the chance to top the standings, suffering a shocking 1-nil defeat at the hands of Levante.
Los Blancos dominated the first half, as they created better chances, but were wasteful in front of goal.
It was the hosts who broke the deadlock, after José Luis Morales scored the winning goal with a powerful shot from a tight angle, with 11 minutes remaining.
The result puts Madrid in a shaky situation, ahead of their champions league last-16 first leg at home against Manchester City.
