Spanish champions Barcelona closed the gap on current leaders Real Madrid with a 4-0 victory over Real Zaragoza in the Nou Camp this evening.

Pep Guardiola's side all but sealed the win before the break courtesy of goals from centre-back Gerard Pique and Lionel Messi.

Barca continued to dominate after the restart and added a further goal through Pique's defensive partner Carles Puyol.

There was still time for substitute David Villa to add a fourth when he headed into the net from close range.

Barca remain unbeaten at home this season.
