The next El Clasico is just around the corner, kicking off at the Nou Camp on October 26th.
It is a rivalry that has become famed beyond Spain's borders.
However, there has always been a perception that Real Madrid is the establishment club that was favoured by the Franco regime and that Barcelona is the bastion of Catalan nationalism that fought back against right-wing oppression under it's motto 'Mes Que Un Club'.
The narrative is one that could fit perfectly into a movie but like most things in this world, the story is far more nuanced than the common narrative.
Spanish football expert Sid Lowe was on Off The Ball last night to chat to Ger about his new book Fear And Loathing In La Liga which looks at the pre-eminent rivalry in Spain.
Debunking myths along the way, Lowe studied a range of documents that showed that there was no divide between Real and Barcelon during the Spanish Civil War.
He also found out more details about the transfer saga of all sagas involving Real Madrid legend Alfredo Di Stefano who might have ended up joining Barcelona.
It has long been alleged that the Spanish regime made sure that the Argentine-born superstar joined the capital side instead of Barca.
Lowe interviewed Di Stefano for his book and discovered that the truth about that transfer is far more complicated than people believe.
