Barcelona are now one point behind Real Madrid after a thumping win over Getafe.
Alexis Sanchez curled home a brilliant opener in the 13th minute and the prolific Lionel Messi's 39th goal in La Liga this term - his 61st in all competitions - had the hosts two up at the interval.
Two superb headers in the final quarter - from Sanchez and Pedro Rodriguez - sealed Barca's 10th straight win which ensured the Catalan side kept up the pressure on Real Madrid, who visit city rivals Atletico tonight.
