Real Madrid's game at Rayo Vallecano was postponed until Monday because of an electricity blackout on Sunday at the Vallecas Stadium.
According to the President of Rayo, Raúl Martín Presa, sabotage caused the blackout.
"Vandals have cut cables," he said. "We have tried to solve the problem as quickly as possible but told the stewards not to open the doors of the stadium. We will leave it to the police to find out who is responsible."
Barcelona -- after a scoreless 87 minutes -- beat Granada, 2-0, on Saturday on a Xavi strike and an own goal. First-place Barca is perfect with 15 points after five games while defending champ Real Madrid has four points after four games.
