Spain's top two clubs are scheduled to meet at Camp Nou on October 26, but there are fears of safety in Catalunya due to political unrest.
Earlier this week, nine Catalan political leaders were jailed for between nine and 13 years, for their roles in the controversial Catalan independence referendum in 2017.
That sentencing sparked political unrest in the region, with demonstrators forcing one of Barcelona's airports to temporarily close on Tuesday.
Similar protests are planned for the day of El Clasico and it's now being reported by Marca that neither La Liga or the Spanish government want the fixture played at Camp Nou.

La Liga have even asked the Spanish Football Federation (RFEF) to play the match at the Bernabeu instead, but both Madrid and Barca are against that idea.
With neither club in support of that idea, a postponement is being seriously discussed.
"It seems to us that, with the way things are going, we consider, along with LaLiga and the RFEF, that, for security reasons, it's not reasonable to play this match as it is scheduled," sources of the Superior Minister of Sport told Marca.
Per the Mirror, two alternative dates are being looked at - December 4 and December 18.
Nothing is confirmed yet, although a decision is expected to be taken on Thursday or Friday at the latest.
The final call is in the hands of the RFEF's Competition Committee, which is composed of one representative from the league, one from the federation and one independent member.
If El Clasico does go ahead as planned on October 26, then it will be a top of the table clash.
Madrid are currently leading La Liga, with 18 points from 8 games. The Blaugrana, meanwhile, are just two behind on 16.News Now - Sport News
