The striker scored twice, as did teammate Cristiano Ronaldo, to keep the Spanish side at the top of their group.
The 25-year-old told reporters: "We played a great match, we changed the system a bit and played with three up front.
"The manager continues to believe in us and he is very happy with our work tonight. We need to continue in this manner, we are the ones that can make the games easy and if we keep playing like tonight things will go well."
No other team in Group B has claimed a win from their first two games in the group stage.
