Regarding Zidane, I think the opportunity to coach Madrid is still quite big, but in the near future that will never happen. Ancelotti is still showing a very satisfying performance, especially next season with the addition of new ammunition, Los Blancos will certainly be able to win any trophies more easily. Previously, Xabi was also linked with Madrid, but Ancelotti decided to renew his contract.
Real Madrid should keep using the service of Ancelotti, he is doing well for them and there's no reason to sack him. Ancelotti has the experience that Real Madrid needs to win trophy. Real Madrid doesn't need a young coach because they have too many young players as they're trying to rebuild the team therefore they need an experience coach that can guide the team and he'll also be repeated because young players are always disrespectful but Ancelotti commands respect due to his many achievements. Zidane should stop trying to coach Real Madrid's, he should go and look for other big challenge in other leagues or he goes to Saudi Arabia and develop the football that they're trying to build. Zidane don't have the experience that this current Real Madrid teams will need to develop into the beast that they are meant to be.
