Ruud van Nistelrooy broke the deadlock after 65 minutes before Robinho secured the full points of the game 11 minutes later stretching the Merengues' lead to 7 points on top of the table.

Real had strong start and dominated the game in terms of possession but couldn't break through the visitors' defense.

Gabriel Heinze had to quit the game in the 17th minute leaving a big gap in defense that couldn't be fulfilled by Miguel Torres.

The hosts' back four failed to keep up with Real Zaragoza's striking department as Diego Millito, Ricardo Oliveira and Sergio Garcia went very close to opening the score.

Casillas produced a wonderful display making some heroic stretches to keep his clean sheet denying close range chances from Millito, Sergio and Oliveira.

Coach Bernd Schuster brought in Guti to replace Wesley Sneijder and it helped in sharpening Real's offensive efforts.

Twenty minutes after the break Van Nistelrooy connected with Robinho's cross to put his team ahead before the Brazilian could secure the victory after an impressive individual effort.

It wasn't a brilliant display by the defending champions but efficient as they had now 44 points seven ahead of second-placed Barcelona.
