New La Liga champions Barcelona tumbled to a 2-1 defeat to Real Sociedad on Saturday before receiving their trophy at a packed Camp Nou. Barcelona's celebrations in Cornella were disrupted by Espanyol fans' pitch invasion, but they made up for it after defeat as they lifted their 27th league title. Barca captain Sergio Busquets was given a standing ovation as he was substituted in the final stages, in his penultimate home game before he leaves in the summer. After Busquets collected the trophy Xavi was thrown into the air by Barcelona's players in celebration, before they danced around a banner in the centre circle proclaiming "La Liga is ours, the future too." "No one doubt that this is just getting started," said Busquets in a speech on the pitch.
