LONDON — Real Madrid has finally, deservedly, broken the spell of Barcelona’s domination in Spain. José Mourinho, a winning coach in every country that has employed him, has achieved what he set out to do. And Lionel Messi is the top goal scorer, ever, in a European soccer season.

The only thing missing from this season of Spanish league superlatives is that neither Madrid nor Barcelona reached the UEFA Champions League final, to be played later this month. They drained one another in their monumental Clásico, which was played between their home and away Champions League matches in the semifinals series won by Bayern Munich and Chelsea.

But, enough of failure.

Madrid’s capture of the Spanish title came Wednesday night with a 3-0 victory in Athletic Bilbao’s San Mamés stadium, where none of Madrid’s previous 31 championships had been clinched before.

“No one gifted us anything,” said Mourinho after his players stopped tossing him into the air.

He spoke on Real Madrid TV, because he does not trust the local media, who had earlier accused Mourinho’s Real Madrid squad of lacking the good taste of previous versions. Mourinho spoke, and one by one his players spoke, of the suffering it has taken to overhaul a Barcelona squad that had won La Liga the previous three seasons — and had hardly dropped in its standards this campaign.
