What is the team news?
Gareth Bale has been ruled out after a calf injury he picked up in the first leg of this tie.
Bale has had an injury-troubled season and will not be risked against Bayern, a muscle injury now having struck after the injury surgery he had earlier in the campaign.
"He's worked hard to get back with the team and after his injury, three months off, he returned really keen," said Zidane.
"He has some discomfort that is preventing him from being at his best and I hope he'll be back with us soon. He's not going to be with us tomorrow as we don't want to risk him.
"He's keen to return, he's worked hard and deserves to be with us as soon as possible. I hope it'll be in time for El Clasico, but I can't guarantee that. We'll take it day by day."
Bayern Munich chairman Karl-Heinz Rummenigge is optimistic that defenders Mats Hummels and Jerome Boateng will be able to overcome injuries in time to face Real Madrid in the return leg of their Champions League quarterfinal on Tuesday.
Bayern, which needs to overturn a 2-1 defeat from last Wednesday's first leg in Munich, is confident Robert Lewandowski will be able to play after the Poland striker took a full part in training on Sunday.
Hummels suffered an ankle injury in training the previous Sunday, while Boateng was also rested for Saturday's scoreless draw at Bayer Leverkusen due to a thigh problem. Both completed individual training exercises on Sunday.
"There'll be a test tonight," Rummenigge said before the team departed for Madrid on Monday. "Everything went well yesterday in training, also with Boateng. Robert was even training with the team. We have to wait. At the end of the day, we're not so pessimistic."
What are they saying?
"Lewandowski is a real number nine and a bonus for Bayern," Madrid coach Zidane said at a press conference.
"Bayern have a great team in all departments so we have to be focused on what we have to do. We know that they have a lot of ways to cause problems for their opponents and they also have flaws."
What are the odds?
Real Madrid 6/4
Bayern Munich 23/12
What's our prediction?
Real Madrid will head through with a second-leg, and therefore aggregate, win.
