Coach Jose Mourinho was lured to one of the world's richest clubs to build a dynasty that would end Barcelona's pre-eminence and he struck what could be a decisive blow in La Liga's title race with a 2-1 victory over the champions at the Nou Camp on Saturday.
With a seven-point lead at the top of La Liga and four matches left, Real now divert their aim to Barca's European crown.
Mourinho's team will need to replicate the defensive rigour and clinical finishing that did for Barca if they are to reach next month's Champions League final in Munich.
Normally outspoken and provocative, Mourinho has recently shunned several news conferences, leaving number two Aitor Karanka to handle the media with anodyne responses.
The rules of European football's governing body UEFA dictate the head coach must speak to the media before the home game against Bayern.
However, the lack of controversy seems to have benefited his team, particularly ahead of the 'Clasico' which they won for only the second time in 11 attempts with Mourinho at the helm.
"We were able to rid ourselves of the pressure we felt in previous encounters," Real captain and goalkeeper Iker Casillas told reporters.

Mourinho, in his third successive Champions League semi-final, is eyeing a third triumph in Europe's elite club competition after his victories with Porto in 2004 and Inter Milan in 2010, the latter after a 2-0 final win over Bayern at the Bernabeu.
His opposite number on Wednesday, the hugely experienced Jupp Heynckes, also knows the Spanish capital well having led Real to European Cup glory in 1998.
Bayern, who have won three out of four semi-finals against Real, have a slender advantage thanks to Mario Gomez's late strike in the first leg and arrive boosted after Franck Ribery grabbed a stoppage-time winner at Werder Bremen on Saturday.
Hours later Borussia Dortmund sealed a second consecutive Bundesliga title that killed off any lingering hopes of an unprecedented German treble for the Bavarians.
The win over Werder was the perfect dress rehearsal if they are to
