Real Madrid coach Zinedine Zidane was pushed about Sergio Ramos and Eden Hazard ahead of their Chelsea showdown.
He remained tight-lipped on whether Ramos would be fit to start the match.
"Tomorrow you will see if [Ramos] plays," he said.
"I am not going to say.
"If he is here it is because he is well, and that is the most important thing for us, to have our leader and captain.
"We are not going to risk anything, if he is here it is because he can play."
He went on to add that Eden Hazard could play a decisive role in the tie.
"It is a good moment for [Eden] Hazard," he said.
"I am sure that he will help us.
"He will bring his quality for us."
