I think this is Mous strategy, as he have shown displease with how the Bernabeu supports the team in important games. It's not the first time that the team and organization put emphasis on the importance of the crowd as a message to the fans before a big game. It's none the less kind of sad. Albeit, I think it's going to be very effective to ramp the atmosphere up:

CR7:
"I expect the Bernabeu to score the first goal. The crowd has to play the most important role as soon as we step onto the pitch because we can feel it. Things will turn out well if we stand united. It will be a decisive match and we players are more confident when we feel the affection of our supporters. We feel we can do even better."
