Real Madrid CF moved a commanding seven points clear of rivals FC Barcelona at the Liga summit after producing an impressive 2-1 victory at the Camp Nou, according to uefa.com. It was a supremely industrious performance from Jose Mourinho’s side, while Barca failed to impose themselves with their customary passing style. Set-pieces proved a profitable avenue for the visitors, who took the lead on 17 minutes from Angel Di Maria’s corner when Pepe’s header was repelled by Víctor Valdes and Sami Khedira pounced to score. “It wasn’t easy winning here but it was a fantastic game and we’re thrilled to take the three points,” said Iker Casillas. “It’s a huge step towards the title but we’re not champions yet.”Elsewhere RCD Mallorca edged a 1-0 win against relegation-threatened Real Zaragoza, who are now level on 31 points with Real Sporting de Gijon, 2-1 winners against Rayo Vallecano de Madrid.
