Real Madrid fans turned on Kaka during yesterday's 1-1 draw with Malaga.
Despite calls from coach Jose Mourinho to the Santiago Bernabeu crowd to get behind his players, Kaka was jeered whenever he was on the ball against Malaga.
The boos and whistles were at their loudest on 19 minutes when he messed up a counter-attack and again he was jeered on 33 minutes when losing possession.
Kaka was taken off on 66 minutes to a mixed response, with some sections of the crowd applauding the Brazilian, while whistles could also be heard.
