Barcelona had looked the better team for most of the match, but Marcelo's goal meant that they only had a one-goal advantage to show for their dominance until the 75th minute.
La Blaugrana broke from a Ter Stegen throw incredibly quickly, going from one end of the pitch to the other in under 20 seconds.
Sergi Roberto bore down on the Madrid penalty area, before curling an accurate pass to Luis Suarez around 15 yards out.
The striker had a lot to do, flanked by Real Madrid defenders on either side, but his first touch stunned the Nou Camp.
Rather than control the pass, the Uruguayan stooped and threw his entire body into a powerful header.
Such was the speed of the headed shot that Thibaut Courtois was beaten from 15 yards out.
Suarez had already won and scored a penalty in the match, and this was a fine way to double his tally.
