The match on Saturday will kick off at 16:00 CEST with no fans in attendance, but most of the focus in the build-up has been on Real Madrid's back-to-back defeats against Cadiz and Shakhtar Donetsk.
"That's what they say [that my job is under threat] - I won't deny it," Zidane said. "What changes? Last year the same, in the first spell the same... What I have to do is my job, the rest is irrelevant."
The losses to Cadiz and Shakhtar have understandably brought with them a lot of criticism, and the Frenchman tried to explain just why Real Madrid ended up losing to these two teams.
"We got off to a bad start in the sense that when we conceded a goal, we found it hard to get our heads up again," Zidane explained. "We found it difficult to play against a team that sits so deep, but in football there are ups and downs and you have to accept that.
"We want to now focus on a different game tomorrow and forget about what happened the other day. We have the chance to turn things around and it's a good and special match to do so."
