Javier Tebas explains why he would suspend the Copa del Rey final
La Liga chief reflects on the Copa del Rey final and Barcelona fans
"If the [Barça] fans plan to whistle during Spain's national anthem in the Copa del Rey Final, the match should be suspended, but I do not control that. I don't predict there will be whistles. I am very certain the fans will whistle."
"If the fans whistle, we will have to use Article 155 within the stadium."
Article 155 of Spain's constitution allows the state to seize back some powers from Catalunya forcefully.
