The former Manchester United star struck twice in the 3-0 win and then declared he was "sad" with his situation at Real. Talk of a move away has already swept across the European media.
Speaking to reporters after the match, Ronaldo explained he was feeling down and that it was due to a 'professional' rather than 'personal' issue.
"I don't celebrate goals when I am feeling sad and that's the case today," said Ronaldo.
"The people who work here know why and I won't say any more than that."
