Barcelona and Real Madrid suffer pre-break slumps

Both sides were coming off tricky Champions League fixtures in Germany. Both sides were missing their key playmakers, Leo Messi and Luka Modric. Both managers indulged in a bit of rotation. Both came a cropper.
It seems silly to talk of a crisis at Real Madrid, still unbeaten this season, but this is the fourth match running which they have drawn when they should have won.
