1) A very high salary, in the region of €10m/year net + ample bonuses;
2) A number of people to be hired as his staff;
3) A number of impossible players to pursue (Casemiro, Pogba, Son, Kane)
4) A very long contract for the Italian standards, five years at least.
I would not believe all of that, really, but even at a fraction his case was impossible because of Juve’s present situation: aging and tired squad, too many expensive players under contract already, Covid impacting finances.
On the contrary, Pirlo comes very cheap and with the idea to keep this instalment going, maybe switching back to a more suitable 3-5-2 system without Sarri’s robotic instructions.
