Ronaldo netted in Los Blancos' 2-0 win over Copenhagen to claim his ninth goal of the campaign.
The strike saw Ronaldo overtake Filippo Inzaghi as the record holder, and Ancelotti told reporters: "I do not think Inzaghi is satisfied today with losing his record [for goals in the group stage], but Ronaldo is a complete forward.
"The team is close to what I was looking for. Defensively we're doing well. We have only conceded a single goal in our last five matches. There is a good balance and we have to keep that."
Elsewhere in the group, Juventus' visit to Galatasaray was postponed due to adverse weather conditions in Turkey.
