Kudos to him for the last results, but I have the feeling that these last two games were partially gifted by two naive displays both from Liverpool and Barcelona. Both way too open and exposed at Real's ground, with a very soft defence being naturally punished at the counter. You have to praise the man for being smart, adaptative and having no complex in terms of tactics, but as good as they looked they are yet to face bigger obstacles this season and we'll see what happens then. I'm looking forward to a potential Real-Chelsea as it could be very, very tight and interesting.
In any case Zidane deserves praise for getting gold from the war veterans in there, but surely a platform that includes Ramos (36), Modric (35), Kroos (31), Benzema (33) won't last eternally and they need to start planning something. These are essentially the same guys he started managing like 5 or 6 years ago, and players like Marcelo, Carvajal, Isco have remained there in decline under his umbrella while younger ones like Reguilon, Llorente, Achraaf have left the team and some others like Odegaard and Jovic could follow in the summer.
If these moves are decided by him or the board I don't know, but from the outside at least he seems too reliant on experience and averse to introduce new elements in the formula, which has brought them balance and tactical expertise, the class on the ball from their main players, but I think is limiting their options in terms physicality and pressing with such an ageing core.
They look to me like a classic good italian team in a more modern era, and as it happens with the likes of Conte or Allegri doesn't seem to be a big margin there for young players learning their trade. Except Vinicious I can't see anything in development to take over in the near future. But at the same time and for that reason their mechanics as a team are polished like a swiss clock, they're extremely well organized and Zidane has made them hungry again so the door is open for them to win things. But hey, let's see how the season pans out before building him a statue.
Also, if their old guard steps down soon, more or less at the same time as it happened to us with Rio, Vidic, Evra, Giggs and co., let's see how they replace all that leadership and know-how with hierarchic players, added to the holes they need to fill already. It doesn't look like they're doing the homework in that regard.
Barcelona in comparison are a soft team under Koeman, bland in both boxes and with many young players around like Pedri, Dest, Mingueza, Araujo, now that Moriba guy too who almost scored against Real, Dembele and De Jong at 23. And even then they're still close in the league table despite Messi going ghost for the first half of the season.
At this stage and before seeing what happens I'd say good work overall from Zidane since his return, there's no denying. But I'm not as impressed as many others.
