Kaka is disappointed to hear fans whistling the Portuguese star.
"I told him to stay at Madrid. When things don't work out at the club they get blown out of proportion.
"Hearing Cristiano being whistled at the stadium after all he has done at Madrid does no-one any favours and I wish the fans showed him some more respect .
“I feel that fans are far too demanding with the players and not just with Cristiano. The same happened with the likes of Zidane, Raúl and Casillas. That's the way it's always been."
