The Los Blancos forward scored twice as they beat Bayern Munich 4-0 on Tuesday to reach next month's final.
The Portugal international told Sky Sports News: "It was a special moment to score 16 goals in the Champions League, it's a great record, so I feel glad for that.
"The main point though is we appreciate that we are in the final in Portugal. It would be a dream to win the Champions League in my country, in Lisbon. We're going to work hard to win this amazing trophy.
"I don't have any preference [over Chelsea and Atletico Madrid]. Both of them are very strong, let's see what is going to happen."
