#1 New coach

In the history of humanity, there have only been a very, very few instances when a change in power of any organization was smooth. Even in a democracy, the transition of power almost often causes hiccups.
So when a new manager takes over from his predecessor – a highly successful one at that – it is only natural for things to be a little erratic in the beginning. Julen Lopetegui’s football system is completely different to that of Zidane.
While the Frenchman brought the best out of an individual player, Lopetegui always tries to implement a system wherein the individual skills of each player produces the best in a collective manner.
From Zidane to Lopetegui, this is actually a big change tactical-wise and it will take at least a season for the Blancos to completely implement what the Spaniard intends to.
Even something as small as a caterpillar takes around three weeks to turn into a butterfly and we are talking about an entire football team here.
