Barcelona-Real Madrid Estaladas flown by fans in crowd

Minute's silence observed for Chapecoense before El Clasico

As they did in the Champions League, Barcelona fans were given 30,000 Esteladas by Catalan groups to be waved against Real Madrid in El Clasico.

The initiative was the work of the National Catalan Assembly and involved having dozens of volunteers distributing the flags in the streets around the Camp Nou.

Fans waved the independence-associated flags at 17 minutes and 14 seconds into the game between Barcelona and Real Madrid.

UEFA have continually punished Barcelona for their waving of the flags in continental games, which they did in the Champions League final against Juventus in Berlin and at every home fixture since.

Barcelona's appeal case against a 150,000 euros fine is currently pending with the Court of Arbitration for Sport.

Before kick-off in El Clasico, Barcelona fans also unveiled a large banner bearing the slogan 'Welcome to the Catalan Republic', which was taken down after a few minutes.
