Cristiano Ronaldo received whistles at the Bernabéu during Real Madrid's 5-0 victory over Rayo Vallecano.

Fans were frustrated at Ronaldo's refusal to play the ball to his teammates. Gareth Bale and Karim Benzema also received jeers.

“I have always said that sometimes I understand whistles because they can be deserved,” Carlo Ancelotti told the media in quotes reported on Madrid’s official website. “Right now, no -- the players are putting in a lot of effort. We need the help of everyone. Whistling Cristiano isn't comprehensible.”
