It was Ronaldo's second hat-trick on the bounce.
He said: "We played a good match in all aspects and we are happy. It is very important for me to score goals, but the most important thing is the team.
"It will be a tough match, I think we are doing well, we are all committed to getting a good result. They have a good chance too because they have a very good squad and there is not much difference between the two teams, but we have confidence."
