Barcelona survived the sending-off of Sergi Roberto to maintain their quest to finish the La Liga season unbeaten after a 2-2 draw with Real Madrid at the Nou Camp.
The midfielder was dismissed following an off-the-ball altercation with Marcelo on the stroke of half-time, but the hosts survived a late assault to take a point.
Barcelona led twice through Luis Suarez and Lionel Messi only for Real, who have one eye on the Champions League final against Liverpool later this month, to level through Cristiano Ronaldo and Gareth Bale.
Real boss Zinedine Zidane will be more concerned over Ronaldo, whom he withdrew at the interval after sustaining a knock.
With Barca's title already assured and Real's minds elsewhere, there was a strangely muted atmosphere at the Nou Camp for a game only really notable for it being the final 'El Classico' for Barcelona great Andres Iniesta.
Real keeper Keylor Navas had saved superbly from Messi before Barca's hopes were hit in first-half injury time when Sergi Roberto and Marcelo appeared to clash off the ball, and the home player sent off.
Real then dominated the later part of the game as they sought to end their opponents' proud unbeaten record this season, but the hosts held firm.
