Real Madrid extended their dominance over city rivals Atletico and maintained their one-point lead at the top of La Liga when Ricardo Carvalho and Mesut Ozil scored in a comfortable 2-0 home win on Sunday.
Barcelona had moved two points clear with a 3-1 success at Getafe, Lionel Messi, David Villa and Pedro netting for the champions, before Jose Mourinho's Real snuffed out Atletico's bid for a first Madrid derby win in more than a decade.
Real have 26 points from 10 games, Barca are second on 25 and Villarreal, who fought back from a goal down at home to beat Athletic Bilbao 4-1, third on 23.
Espanyol are in fourth after their 1-0 win over visiting Malaga on Saturday and Valencia can move above them with a win at Sevilla on Monday.
However, Atletico strikers Diego Forlan and Sergio Aguero saw too little of the ball and wingers Jose Antonio Reyes and Simao threatened only rarely down the flanks.
After his Portugal defensive partner Pepe had gone close with a header at a packed Bernabeu stadium, Carvalho burst through from the back to fire Real ahead in the 13th minute.
German international Ozil, a firm favourite with the Real faithful following his move from Werder Bremen, then bamboozled Atletico goalkeeper David De Gea with a low, swerving free kick from wide on the right to make it 2-0.
Toothless Atletico's best effort of the first half came in the 36th minute when former Real and Arsenal winger Jose Antonio Reyes forced a fine save from Iker Casillas with a curled shot.
Real striker Gonzalo Higuain and Forlan hit the woodwork with superb volleys in the second half but Atletico never looked like getting back into the match.
RICH VEIN
Portuguese Mourinho said he had instructed his players to slow down the pace of the game to allow them to control it more easily and nullify Atletico's attacking threat.
"My players were very good and if we did not put on more of a spectacle it was because of our opponent and not us," he told a news conference. "You can't beat a team like Atletico by six or seven."
World Player of the Year Messi continued his rich vein of scoring form by taking his tally for the season to eight, three behind Real's Cristiano Ronaldo.
Getafe crowded their own half but Barca weaved an intricate web of passes to set up Messi after 23 minutes and the Argentine scored inside the near post.
His subtle layoff created the second for Villa and Pedro grabbed the third after Barca pressured the home defence into a mistake in the 65th minute.
Barca defender Gerard Pique then earned his second yellow card and was sent off for handling the ball in the area and Manu del Moral pulled one back for Getafe from the penalty spot.
With the visitors rattled, Getafe pressed forward but a red card for midfielder Derek Boateng took the wind out of their sails and Barca could have scored again in the final minutes.
"It's never straightforward coming here," Barca coach Pep Guardiola told a news conference.
"It's a good sign that we finished off the match in the way we did. It might have looked easy but it wasn't."
Bilbao's Spain striker Fernando Llorente struck with a back-post header after only six minutes at the Madrigal but Villarreal turned the game around before the break.
Brazilian Nilmar levelled with a header and Spain's Santi Cazorla capitalised on a poor clearance to score.
Bilbao had defender Jon Aurtenetxe sent off for a second bookable offence and Italy's Giuseppe Rossi and Ecuador's Jefferson Montero grabbed late breakaway goals.
Elsewhere, Real Zaragoza climbed off the foot of the table with a 3-2 home win over Real Mallorca thanks to a stoppage-time penalty from Gabi.
