Zlatan Ibrahimovic came off the bench to volley 10-man Barcelona to a 1-nil home victory over Real Madrid which put them back on top of La Liga in Spanish football.
Cristiano Ronaldo missed the clearest chance of a first half in which the visitors successfully frustrated Barca before substitute Ibrahimovic made the breakthrough by smashing a volley past Iker Casillas in the 56th minute.
Shortly afterwards, Barca midfielder Sergio Busquets foolishly picked up his second yellow card to leave his side a man short for almost 30 minutes.
But Real could not make the extra man count in a pulsating finish and it needed a superb save from Casillas to deny Lionel Messi at the end. Real had Lassana Diarra sent off in the 89th minute.
Champions Barcelona have 30 points from 12 games, two ahead of Real who slipped back to second.
