Real Madrid expressed significant frustration last weekend over their scheduling, having to play against Villarreal on Saturday after competing in the Champions League round of 16 just three days earlier.
Carlo Ancelotti even hinted at the possibility of boycotting future matches if his team continued to face such tight turnarounds.
However, Barcelona now find themselves in an even worse situation.
The Single Judge of Professional Competitions has dismissed the appeal filed by both Barcelona and Osasuna regarding their rescheduled fixture, forcing Barça to play two matches next week with only 64 hours between them.
