Real are overwhelming favourites going into the game.
But Zidane says: “The game will be more difficult than people think given that it comes after two huge games this week, after which everyone is a little tired. We have been regaining our energy over the last few days as we will need it.
“The important thing is what we are doing right this season. We are going to keep on doing so, giving everything because it will be a tricky game after the other two that we have had this week, where we gave our all and put everything into the games."
