Isco spoke about Real Madrid fans chanting that they did not want the Copa del Rey final played at the Santiago Bernabeu.
The finalists, Barcelona and Sevilla, would like it to take place there, but Madrid are resisting.
Los Blancos fans sang "the final will not be played here" during their 4-2 win over Athletic Club.
Isco backed the chants, saying: "I would sing too. As a Madrid fan I wouldn't like it."
Coming from a Real Madrid player that is not a surprise, but it should be remembered that Isco used to be a fan of Barcelona.
