Ronaldo warned it is still early days though, saying in AS: "We need to continue fighting, there is still a lot of the season left and we need to continue improving."
Ronaldo also insisted his side need to focus on themselves rather than on arch-rivals Barcelona, who have yet to hit top form this season but nevertheless are just a point behind the capital club.
"There's no need to think of the others, we need to think of us. To continue as we have been doing, playing well and scoring a lot of goals. We don't have to be concerned with Barcelona," Ronaldo added.
