Allegri came also from the bottom

He coached first Aglianese, SPAL, Grosseto and Sassuolo before he joined Cagliari and got fame.
He promoted Sassuolo from Serie C to Serie B isn't it?
A lot of Italian coaches came from the bottom btw. What do you think of Ancelotti who started at Reggina (?) and Lippi who also started in Serie C. Same for Ranieri etc.
