I think he is a great motivator and player manager. It’s no coincidence that he seemed to have learned a lot from Ancelotti of all people. Their approach strikes me as quite similar. The issue he’s now facing is simply that he‘s not that great of a tactician. So like Ancelotti, he needs midfielders to run the show for him and he needs strong personalities on and off the pitch to lead the team, verbally and by example. I‘m not sure he has that at Real right now. So I think he won’t be successful there for his second stint.
What they need right now is a more tactically focused manager who installs a new approach for the firewalls future. Zidane doesn’t strike me as the guy who can rebuild a team.
Right now, I think he’s the wrong manager at the wrong time for them. But calling him a fraud or suggesting he simply got lucky, is by no means right. He’s an excellent manager, at least he’s been one so far.
