Sarri parted ways with Lazio towards the end of last season.
He told Il Corriere della Sera: "Unfortunately it's like this. And honestly I'm a bit sorry.
"There were free benches in teams that I imagined could be good for me. I wasn't even asked for a chat. It's up to the presidents to decide."
Asked if his outspoken ways have worked against him, Sarri continued: "Crowded calendars and a pitch that is often not up to par? Yes, I repeat it. The point is that Klopp and Guardiola also said it but no one commented, if Sarri is the one complaining then the heavens will open up. I'll ask you a question: would you let himself be operated on by a surgeon who has a rusty scalpel? Well, a footballer can't play on an unsuitable pitch."
On winning the Scudetto with Juventus, he added: "It was a journey of great suffering, with lots of arguments in the family. Let's say that as a Napoli fan I struggled. I shouldn't have left Chelsea, that's it."
