Ronaldo is expected to be the subject of unfriendly attention from the Anfield crowd due to his prolific time with Liverpool's great rivals Manchester United.
However, Ancelotti has insisted that his star man will feed off the atmosphere inside the stadium.
"No, he won't be more motivated because it's Liverpool," Ancelotti told The Sun.
"Cristiano is always super-motivated. But, if the atmosphere is hostile, this motivates him more."
Ronaldo scored 17 Champions League goals last season as Los Blancos won their 10th European Cup.
