Simone Inzaghi wants to repeat Cristiano Doni's heroics for Atalanta last season.
"My brother Pippo also told me that this was a place with a great atmosphere.
"I had other offers as well as the chance to stay in Rome, but I really wanted to play for Atalanta because this is an ambitious club and I will get to play first-team football here.
"I had back troubles which have caused problems recently.
"I'm fit again now, but in the meantime Tommaso Rocchi and Goran Pandev have emerged at Lazio so it would have been very tough for me to play there."
