Ronaldinho scored two superb individual goals as Barcelona romped to an easy victory over Real Madrid.
Ronaldinho earned a standing ovation from the home fans
Samuel Eto'o had put the visitors into a deserved lead after just 15 minutes with a superb low opportunist finish.
Just before the hour mark, Ronaldinho skipped past two challenges before racing into the box and firing the second past the helpless Iker Casillas.
He repeated the trick on 77 minutes, showing great pace to work an opening down the left and slide the ball in.
The Brazilian's second goal prompted the home fans to applaud his display - a rare show of admiration towards a player representing their bitterest rivals.
Madrid had little to offer in response as Barcelona enjoyed their 14th league victory at the Bernabeu.
It put the champions top of the table for the first time this season and made Frank Rijkaard the only Barca coach to lead the Catalans to two victories in the Real Madrid stadium.
Eto'o set the tone for the evening as he netted the opener against his former club when he snapped up the ball on the edge of the penalty area, turned inside three defenders and fired the ball under Casillas.
Ronaldinho, fancied to add the European Footballer of the Year to the World Player award he won last year, shone in the second half and capped his display with his superb double strike.
Real were jeered off by their own fans who had little choice but to marvel at the ease of their opponents' victory.
