The president of Spain's Professional Football League (LFP), Javier Tebas, has said he is in favour of calling off the Spanish Cup final if fans whistle or boo the King of Spain or the country's national anthem.

"This cannot be allowed to become tradition or habit simply because it has happened before. Call off the final? Why not?", he said.

"I don't think it right for fans to whistle or boo the king or the national anthem. It isn't within my remit, but I'll do whatever I can to stop things like that from happening", he added.
