Lionel Messi scored the winning goal from the penalty spot in the 72nd minute after Isaac Cuenca was felled by Pedro Botelho inside the Levante box.

"Guardiola spent the entire match putting pressure on the referee," Valdo told Telemadrid.

Barcelona remain four points adrift of leaders Real Madrid in second place, while Levante are still fifth ahead of Osasuna, who are in action against Betis on Sunday.
