Madrid however have made clear they will ‘not be getting off the plane’ if the complete safety of their players cannot be assured.
The Clasico had been originally scheduled for October 26 but had to be postponed following a wave of pro-independence demonstrations in Barcelona in the wake of the jailing of nine Catalonian political leaders.
Talk had gathered pace of a potential second cancellation of the showpiece fixture due to rising political unrest in Catalonia.
With the revised fixture set to take place on December 18, political group Tsunami Democratic are planning another protest at the Nou Camp just four hours before kick-off.
Tsunami Democratic is a Catalan group which is advocating for a self-determination referendum on the independence of Catalonia.
They are reportedly planning to establish four rally points around Barca’s famous stadium in the hours leading up to the game, knowing that the coverage of the fixture will be beamed around the world.
Over 18,000 people have registered their interest in attending the event, and their presence could mean the game is unable to be played.
Speaking out on the matter, Barca president Bartomeu said:
“El Clasico will be played. It will not be postponed again,” Bartomeu explained, as quoted by Diario Sport.
“It is the responsibility of all of us to ensure it is played. The Camp Nou is a space of free expression. We are living a complicated moment, but everything is compatible with the practice of football if it is peaceful.
“Barcelona are preparing for this game as normal. I would tell everyone to come to Camp Nou as usual, with friends, with family.”
The match had been scheduled to be played at Barcelona’s Camp Nou stadium on 26 October but due to the current volatility of the Catalan political situation, La Liga asked that the game be reversed to Real Madrid’s Santiago Bernabeu stadium.
That proposal was rejected by both clubs involved and with such a fluid period of unrest in Catalonia, the match was instead pushed back to 18 December.
