The reason is the lack of general direction in the club.
It is obvious now that since the start of the season and the overall target was not identified by our board. They, by free will, opted to sign a young inexperienced manager to lead the team while fully knowing of his shortcomings in handling such duty and pressure. At the heart of the season we saw ourselves 2nd and chasing Juve with a single point, thus the thirst of the title woke up prematurely. After the declining phase began we searched for ways to patch things up in regards to our unreal expectations adn squad personnel. Moratti finds himself at the end of the season with nothing but a far-fetched dream of climbing the 3rd spot...
What did they expect from Stramaccioni? What did they expect from the team that was drained from energy in the last three years in front of their eyes? From the staff, coaches, and the players. A young man who will come and challenge for the title? He isn't' Allegri with his experience, and he certainly isn't Conte with his understanding of the game and intensity of this level of football as a player.
Tick tock...
