He was in full flow on an overhaul. Press barred from most training sessions. Interviews and press conferences reduced. The team cook travels ahead of the team to make sure the food's ready when they arrive. Injured players have to report in to the medical department before the training sessions start. He goes to reserve team matches and calls up the interesting ones to train with his squad. This made the official chain on command nervous.
His big crime is opening his mouth in public. He's very direct and the press and the Madrid management hate it.
An example, he's given more time to youth team players than any manager since Del Bosque
including a young striker called Morata. But when the press demanded that he use Morata as his new number 9, he told them, "He's going to be good, but he's next year's player. The reason La Liga's full of good ex-Madrid players is you're too impatient - the press, the agents, the club - you won't let them grow up. Leave him alone. He's only scored 4 goals in the reserves - let him enjoy scoring some goals there, don't act like his work there is worthless."
When he arrived they asked him about Barca, he told them they're a great team and that he could give Madrid a great team in four years. They laughed - four years is incomprehensible for them.
