The Blaugrana currently hold a 16-point advantage over the reigning champions going into the winter break, and the Dutchman feels the competition is already over

And the Dutch icon believes that it is the Spanish public who suffer from this, as the championship looks over before Christmas.
"It's too much, it's a terrible gap," he told Le Buteur. "The truth is that it's not good for La Liga. Perhaps Barcelona supporters are happy, but a championship is valued by the tension and excitement it creates.
"Here the suspense is over."
Barcelona gets back to action after the winter break with a local derby against Espanyol on January 5.
