Jose Mourinho had a nightmare first Clasico as champions Barcelona crushed his Real Madrid side 5-0 at Camp Nou last night to go two points clear of their bitter rivals at the top of the Spanish first division.

Spanish World Cup winners Xavi and Pedro Rodriguez put Barcelona into a two-goal lead after just 17 minutes and David Villa marked his first Clasico with a brace inside two minutes (54, 56) before Jeffren added a late fifth as Mourinho stomached an unforgettable first defeat in charge of Real.

Sergio Ramos was sent off in the final minute for a terrible foul on Messi and then shoving Carles Puyol as tempers boiled over.

For Barcelona it was a fifth successive Clasico win over their arch rivals as coach Pep Guardiola maintained his 100 per cent record in the fixture and exacted revenge over Mourinho, whose Inter side defeated Barcelona in last season’s Champions League semi-finals.

Real went into the game unbeaten and hoping for a first win at Camp Nou since December 2007.

However, Barcelona gave old boy Mourinho, who used to work for the Catalan club as a translator under Bobby Robson, a night to forget with an emphatic win that evoked memories of the 6-2 drubbing of Madrid at the Bernabeu in May 2009.

It was a huge psychological win for Barca in the title race and the omens are good with the winner of the first Clasico going on to be crowned champions in the last six seasons.

Leading standings: Barcelona 34; Real Madrid 32; Villarreal 27; Espanyol 25; Valencia 24; Real Mallroca 21; Atletico Madrid, Sevilla 20.
