On the pitch however, it was business as usual.
Xavi broke the resistance of Valladolid in the 43rd minute when he shot the visitors ahead.
Lionel Messi made it two in the 59th minute, but the home side tried to make a contest of it when they pulled a goal back through Javi Guerra with a minute left.
Christian Tello snuffed out whatever joy that lone strike may have brought, when scored a third for Barcelona four minutes into injury time, to again exteng the lead at the top to nine points.
