El Clasico in recent years has been personified by the competition between Real Madrid's Cristiano Ronaldo and Barcelona's Lionel Messi to see who is the best player in the world.
Sunday's edition of the rivalry offered no clear decision as both players scored braces in a 2-2 draw at Camp Nou.
Real Madrid took the lead in the 23rd minute when Sami Khedira found Ronaldo on the left side of the box as the Portuguese star fired a first-time shot past Victor Valdes at the near post.
The visitors nearly doubled their lead moments later but Karim Benzema's shot rattled the frame before Angel Di Maria misfired off the rebound.
Barcelona equalized in the 31st minute as Messi capitalized on some sloppy play for the Madrid defense. Pepe's failed clearance and a couple of unlucky bounces prevented the visitors from clearing their lines, and Barcelona's Argentine magician pounced on the loose ball to stuff it past Iker Casillas.
Messi emerged with the go-ahead goal in the 61st minute, curling a sensational free kick over the wall and into the upper corner to leave Casillas no chance.
But Real Madrid restored the even score five minutes later as Ronaldo latched on to a splitting pass from Mesut Ozil and instantly slipped a shot past Valdes.
Barcelona produced some glorious chances in the final stages, including a brilliant effort from substitute Martin Montoya that struck the crossbar after some fine build-up play, but the match finished with the two title rivals deadlocked on two goals apiece.
The result spoils Barcelona's perfect start to the La Liga season as the Catalans now have amassed 19 points through seven league games.
Real Madrid, paying the price for a slow start to the campaign, sits eight points behind.
Athletic Bilbao 1, Osasuna 0

Osasuna remains second from bottom in Spain's top flight with just four points.
Granada 2, Mallorca 1
Mallorca, Spain - Granada claimed a second successive victory on Sunday, edging Mallorca 2-1 at the Estadio Son Moix.

Granada was reduced to 10 men moments later when Yacine Brahimi was banished to the stands, but the club still managed to extend the lead thanks to Gabriel Torje's strike in the 76th minute.
Tomer Hemed pulled one back for Mallorca four minutes from time, but it proved to be nothing more than a consolation strike.
