Real Madrid wore black shirts and black shorts, a novelty choice for a fixture whose aura has been built for more than a century around the fame and lustre of their all-white strip.
It meant that Barcelona were also in a form of clasico disguise, dressed in their ‘second’ outfit of yellow with red diagonal stripes.
After an astonishing night at the Santiago Bernabeu, the attire helped write the headlines. A dark night indeed for Madrid, 4-0 losers at home to their greatest rivals, a Barcelona who had lost the five previous clasicos, who trailed Madrid by 15 points in the Spanish table going into this, a match that will be remembered as a landmark in what looks like a Barca revival.
It may also act as a warning to Sunday’s stunned hosts not to mess with traditional kit, even if the marketing department deems it a good idea.
“We could have scored more goals, and I hadn’t expected to be that much better than Madrid,” said Barcelona’s head coach Xavi.
So utterly were Spain’s champions-elect – Madrid have a nine-point lead over second-placed Sevilla in La Liga – rolled over by the old enemy that there was genuine frustration on Xavi’s bench that all-time records for winning scorelines in an away victory in the clasico were not being challenged.
Pierre-Emerick Aubameyang scored twice. He might have doubled that tally had he not offered a tame save to Thibaut Courtois, busy and brilliant in the Madrid goal, in the first half or miscued his connection with Jordi’s Alba’s cross in the second.
