Bale missed Real's Copa del Rey semifinal first-leg win over Atletico Madrid.
Goals from Jese and Angel Di Maria followed Emiliano Insua's early own-goal to give Real a 3-0 victory in Bale's absence.
Ancelotti insisted: "There is no relapse, (Bale) is fine and I just preferred to rest him for Saturday seeing as Cristiano cannot play. Gareth being fresh will be good. He'll probably play.
"The dream is for the team to play like they did tonight at all times. They won a game by playing well.
"Our team showed it can play well and we must do so continuously because now every game is important."
