Karim Benzema netted the winner of the semifinal first-leg.
"I had already decided that Ronaldo wouldn't play 90 minutes because he was out for a while," said Ancelotti in his post-match press conference.
"Bale and Cristiano will both be totally fit for the second leg in Germany. What is important is sacrifice. Di María and Isco made sacrifices and that helped the team a lot.
"Ronaldo wasn't in his best shape, but it was important for us that he played. We are happy.
"Ronaldo sacrificed a lot by playing in a central and defensive position. The whole team has sacrificed a lot."
