Ronaldo was the only one of the three to start Saturday's 4-0 rout of strugglers Osasuna in La Liga at the Bernabeu.
The Portugal forward had stated he was in "perfect condition" before the game after recovering from knee and thigh injuries, and proved it with a sparkling show in which he grabbed a brace before Sergio Ramos and Dani Carvajal were also on the scoresheet.
"Ronaldo, Bale and Benzema will play on Tuesday," the Italian said. "The sooner we score, the better.
"Cristiano is fit. He had more confidence and is totally fit now.
"Bale felt weak and we preferred that he trains individually today (Saturday). He will be ready on Tuesday.
"Benzema is improving, he will train tomorrow and should be ready on Tuesday."
Alvaro Morata led Real's line in Benzema's absence and produced a sound display.
He added: "Morata worked hard but it wasn't easy for him to go through Osasuna's defence,
"Morata is important for us and we need him with Benzema."
