Sergio Ramos scored in the 90th minute to secure Real Madrid a 1-1 draw at Barcelona in Saturday's "clasico" match at Camp Nou.
Ramos charged in to head Luka Modric's free kick past goalkeeper Marc-Andre ter Stegen, who got a hand on the ball but couldn't keep it out.
Luis Suarez's header from a free kick by Neymar had given Barcelona the lead in the 53rd.
The stalemate favored Zinedine Zidane's Madrid, which left Camp Nou with its six-point advantage atop the table intact with Barcelona second.
Madrid also extended its unbeaten streak to 33 consecutive matches.
