Bayern have struggled to take their dominance from the Bundesliga to the Champions League.
Zidane said he may consider using forward Lucas Vazquez in defense, as he did after Carvajal had to leave the first leg because of his injury.
"'It is independent of winning the Champions League - I want to continue at this club", he told reporters.
"But it's not important. I'm expecting a fair form of refereeing tomorrow and I expect his decisions not to interfere with the outcome of the game".
Bayern are without injured Arturo Vidal, Arjen Robben and Jerome Boateng but Heynckes insisted they could reach the final. It can feel as though players at Real Madrid are signed less for how they will fit into the team than how they fill suit the marketing strategy.
The Spanish outfit will take a 2-1 lead into the second leg on Tuesday evening.

Griffin's college coach Scott Frost tweeted "About time", after the pick was made. "I tell you, it's awesome ". Added Shaquill: "I was going to be happy no matter what team that gave him the opportunity".
"The key for us is think about winning the game and to go on to the pitch wanting to do that", Zidane said.
"We are not going to speculate, defend, or any similar odd things... we have to try to score quickly". Defensive midfielder Martinez has recovered after coming off with a head injury in the second half against Real. Sule is expected to come into the team, and while he's a quality option, he'll face a tough time against Cristiano Ronaldo. It now remains to be seen if his Real Madrid career ends with a move to Old Trafford. There's a lot that you need to deal with here when you are a foreign player and it's hard. "We're not in any hurry", Bayern chairman Karl-Heinz Rummenigge said.

That 10 or 20% difference in class was telling and will probably be telling again. "If we want to realise our Kiev dream at the Bernabeu, we definitely need the best performance of the entire season". There is no sense in which, tactically at least, they are breaking new ground.
It's awesome how Zidane has changed them. Another omission here, and Bale's Real future will be a major doubt.
Both Thomas Mueller and Robert Lewandowski went agonisingly close with a string of chances. Centre-back Nacho Fernandez has returned to training for the first time after quite a few weeks but is still uncertain for the midweek encounter. When your main striker doesn't perform, you're in trouble. If that was an audition in front of Zidane and club president Florentino Perez, they won't have been too impressed, but Lewandowski still remains the biggest threat for Jupp Heynckes' side and he'll be hungrier than ever to put right his mistake at the Santiago Bernabeu on Tuesday.
Real Madrid just don't panic.
