Real Madrid coach Carlo Ancelotti said he was amazed that Cristiano Ronaldo, in particular, was the subject of boos from the Bernabeu crowd during Real’s 5-0 rout of Rayo Vallecano on Saturday. The crowd started to boo Ronaldo after he failed to pass the ball during a breakaway in front of goal in the second half of the easy win. "I understand booing every now and then when we have deserved it, but at the moment the players are making a great effort. We have to keep at it and we need everybody's help. But booing Cristiano is not so easy to understand,” the Italian said.
