Julio Baptista gave Real Madrid coach Bernd Schuster the Christmas present he wanted by getting the only goal in a 1-0 win over their bitter rivals Barcelona on Sunday.
The rugged Brazilian striker - nicknamed the Beast - found the net after 36 minutes to bring to an end to Barcelona's 100 percent home record in their Nou Camp stadium this season, both in La Liga and the UEFA Champions League.
Real's triumph puts them firmly in lead of the Spanish championship race and they are now the overwhelming favourites to retain their title.
The 30-time Spanish league winners have 41 points from the 17 games and have extended their lead to seven points over second-placed Barcelona.
Neither side had many chances in a scrappy first 35 minutes in which the biggest threats came from the free kicks of Real winger Wesley Sneijder.
Pepe made Barcelona goalkeeper Victor Valdes work hard to deny him after he connected with one of the Dutchman's dead ball efforts after 11 minutes.
Valdes then flapped badly at a Sneijder free kick on 32 minutes but Ruud van Nistelrooy couldn't get his head cleanly to the ball.
At the other end, Real's Iker Casillas once again proved his credentials as one of the best keepers in Europe when he produced two wonderful reaction saves in rapid succession to thwart Ronaldinho and Xavi Hernandez.
Baptista then got the goal which changed the face of a game which generally lived up to its billing as El Clasico in terms of emotion and effort but not technical excellence on this occasion.
Van Nistelrooy saw Baptista darting down the left wing and chipped the ball across, leaving the speedy Brazilian to out pace his markers Carles Puyol and Rafael Marquez before half-volleying the ball over the head of Valdes.
The first 15 minutes of the second half saw both teams charge up and down the field but neither side appeared to have much idea about how to break down two well-organised defences.
Barcelona's Spanish international Andres Iniesta, normally accustomed to being a midfielder, looked especially uncomfortable in the much more advanced role required of him in this game by Rijkaard.
Casillas produced two good saves from Bojan Krkic and Yaya Toure in the final seven minutes of the game as Barca became increasingly desperate but it was the closest the Catalan club came to getting an equaliser.
Barca held
Rijkaard gambled with starting Ronaldinho but the two-time
former World Player of the Year had little impact and was regularly
stopped in his tracks by some good tackling by Real left back
Sergio Ramos.
The defeat means that Rijkaard will also have to spend the two-week holiday period having to listen to a debate about his future.
The likes of Marco van Basten and Jose Mourinho have been regularly mentioned as potential replacements for Rijkaard if Barca fail to win a trophy for the second year in succession.
Second half goals from Raul Tamudo and Luis Garcia gave Espanyol a 2-1 win at Atletico Madrid earlier on Sunday and the Barcelona-based side move up to third place in La Liga, just one point behind their illustrious neighbours.
Atletico's 'Kun' Aguero was sent off after 30 minutes, the Argentine striker retaliating to a crude tackle by Marc Torrejon.
Despite being a man down, Simao Sabrosa put the home side ahead with a stunning free kick seven minutes later but Espanyol made their numerical advantage tell in the second half.
Raul Tamudo got Espanyols' equaliser eight minutes after the break when he connected with a Luis Garcia corner.
Atletico were then reduced to nine men when Mariano Pernia picked up his second yellow card just before the hour and Luis Garcia got Espanyol's five minutes from time when he hammered home an Ivan De La Pena cross.
