Barcelona have moved to ban Real Madrid fans from their Copa del Rey semifinal.
Barcelona stated on their website that Real Madrid fans who attempt to access 'the local fans area with clothing or symbols of the visiting team will have access denied'.
The website warns that fans who 'enter the venue/stadium wearing clothing or insignia of the visiting team, may be relocated or expelled'.
A similar situation arose before the Copa del Rey quarter-final game against Real Sociedad but in the end the Catalan side backed down and fans of La Real were admitted.
At present there is no established quota of ticket allocations for away fans in the Spanish Cup, a matter that the RFEF are addressing after Atletico Madrid fans were annoyed after being given just 334 tickets for their recent cup clash at the Bernabéu.
