What is it that good coaches see on Bonucci and I don't?
Juventus has 2 excellent central defenders. After that, everything is shit and crap.
When the best of those two excellent central defenders is injured, good coaches will understand that putting shit next to an excellent central defender, is significantly weakening the defence.
So, instead we play 3 centrebacks, and increase the level of central shit to a point where it can be balanced out by our excellent selection of players on other positions.
Thats why we play 3-5-2
You ask why Bonucci is used ?
Quite simply because in a 3cb backline, he isnt shit anymore, he becomes a good ballplaying covering defender, wich very important.
Feel free to say how you disagree with Conte and Allegri. Beeing good at defending is just a state of mind right
