Bale is struggling with a thigh injury and there's no date set for his return.
After victory over Copenhagen, Ancelotti said: "We are not worried, he has not played because of muscle fatigue and it is nothing special. He is waiting to recover his optimal fitness. He was not at 100 % but he will get there because he has 15 days of rest and then will be ready.
"He is not happy and that is normal, he wants to play and is eager but it is not a problem. Now we have time to get him into a good physical condition and avoid injuries."
