But Zidane does not trust the young. It is possible that a different coach will build a new team.
Are you expecting Zidane to leave? I think coach Zidane is good, it's just that he has a lot of pressure at the club. I believe the starting line-up in Madrid is not in balance. This is evident from several matches they lost because their core players suffered injuries. The league standings and champion ambition make him fight to always want to win every game. So he wants the perfect team in every game. If he doesn't field his young players, it's only a matter of time. If you look at it it has happened even if only one or two young players are in a game. I hope Zidane can take advantage of the transfer market.
I totally agree with you that Real should start rejuvenating the team. But it's easier said then done to include younger players. Dortmund for example focuses a lot on very young players but with all the young talents they still aren't really favourites for titles. And Real always wants to be in the top 5 of the world so they rather trust old(er) player that brought them the success in the past. And to just go on a shopping spree on the transfer market now doesn't necessarily bring success and is damn risky. Especially during the corona crisis. (Jovic for example is a young player but was a huge disappointment given how much they spent on him)
However since they lost their semi final today and are already way behind Atletico in the league (even with 2 more matches played), I am sure the officials at Real will want to make quite some changes this summer. Maybe Mbappe and/or Camavinga? Together with Ødegaard, Vinícius Júnior, Rodrygo, Kubo (currently on loan) these players could form a great team.
