Real Madrid knocked bitter city rivals Atletico out of the King's Cup on Thursday with a 1-0 win at a hostile Calderon to go through to the last four 4-1 on aggregate.
Cristiano Ronaldo added to his phenomenal tally of goals this season with a 23rd minute strike to help set up a semi-final over two legs against holders Sevilla after the Andalusian club saw off Villarreal on Tuesday.
Passions ran high on a chilly night at the heavily-policed stadium in the south west of the Spanish capital and the Atletico supporters aimed ugly chants at Real coach Jose Mourinho and some of his players.
The visitors, who have not won Spain's domestic cup since 1993, had an early scare when Iker Casillas was caught in possession by Jose Antonio Reyes, who blocked the Spain goalkeeper's attempted clearance but could not make the most of the rebound.
The home side were then rocked by a double blow. Sergio Ramos was given too much space on the right and Ronaldo powered into the penalty area to smash a deflected cross high into the net. It was the Portuguese forward's 32nd goal of the season in all competitions and followed up on his strike in the 3-1 win in last week's first leg at the Bernabeu.
Reyes then had to leave the pitch due to an ankle injury he had sustained in an earlier tangle with Alvaro Arbeloa and the former Arsenal winger, was replaced by Diego Costa.
Real Madrid coach Jose Mourinho and director general Jorge Valdano have their differences on some issues but both want success for the club, according to captain and goalkeeper Iker Casillas.
"Jorge has his way of behaving and the coach has his," Casillas, who was responding to reports of a rift between the pair, told reporters after Real knocked city rivals Atletico out of the King's Cup on Thursday to advance to the semi-finals. "In a relationship there are always differences about some things but deep down what both want is for Real Madrid to be as successful as possible."
