Petrachi was pushed out of Roma last summer.
On Conte, he recalled: “We have a deep friendship, but I already quarrelled with him regarding Dzeko, who he wanted at Inter.
“Don't push me with Dzeko, I won't give him to you. I told him it's useless to bang your head against the wall.
“He's a player in the hearts of the fans and when I commit to a club, I also commit to the fans.
“He was eager for a new challenge. It's a negotiation I didn't follow, I wasn't at Roma yet. I can imagine that Antonio didn't feel reassured. Perhaps, if he had spoken directly with Pallotta, things would have gone differently.
“Roma wanted an Italian coach and when they missed out on Conte, I later learned they had talked to [Gian Piero] Gasperini, [Sinisa] Mihajlovic and [Roberto] De Zerbi."
