#4 Avoiding the pressures of a high profile appointment
No offense to Lopetegui, but he is not exactly the most famous manager on the face of the planet. By appointing him, Madrid have bypassed the risks that appointing a high profile manager would have brought to the club.
When Zidane was announced first as the manager of Madrid, it was the general consensus that it would only be an interim project - Zidane would see out the 6 months and then another established manager would take over. Then came the Champions trophy. And then two more.
Zidane's appointment turned out to be a blessing in disguise for Madrid, as it subdued the ridiculously high expectations of their fans, as well as satisfy them by appointing a club legend.
Anyone following in the footsteps of a hat-trick of CL trophies is certain to have enormous pressure, and Lopetegui is a clever way to avoid that.
If Lopetegui fails (hopefully he will not), Madrid can always go for another star manager, only this time without them feeling that the job might come with too much baggage. Friendly reminder that this is not a reason to think Lopetegui will fail, but just a way of covering all possible options.
