Zizou is close to the family and the Agnelli's are three feet deep into the world of football. One of our legends just won the WC, another the CL, we have taken the biggest historically championship by the balls. Maybe they have some other projects - france, etc... But dethroning RM-wise and finding a person that speaks superhero language is always a plus when you are reaching to be the best club ever.
Lets just hang in there for a moment and consider that in his modest managerial career Zizou has won 3 CL's consecutively. I know it's a cup competition and they had a massive team , but no one else in the modern CL has done it.
