The former Morocco international believes Allegri was the reason he left Juventus for Qatari side Al-Duhail in January 2019.
Benatia worked with the Italian for two-and-a-half seasons at the Allianz Stadium, where he won two Serie A titles and two Coppa Italia.
Despite hitting out at the 52-year-old, Benatia admits Allegri is a great coach and a good person but he was not happy with how he was treated by his former gaffer.
“He’s a great coach and good person. I had no problems with him or anyone else. He simply made me broken promises,” the 32-year-old told Goal.com.
“During a preseason tour in the US, he told me that the starters would be Chiellini and I, with Bonucci who would have to earn his place.
“I’d just scored twice in the Coppa Italia Final and we were talking about my renewal. Then I found myself on the bench four times without ever playing.
“I felt as if I’d been taken for a ride and said that I’d never play Juve again while he was there.”
Despite his acrimonious exit from the books of the Serie A giants, the former Bayern Munich man insists he holds no grudges with the club and their Portugal superstar Cristiano Ronaldo.
“My relationship with the club is excellent. I still hear from them now.
“Ronaldo is the absolute No 1, as a player and as a person. His brain is quicker than everyone else’s, even off the pitch.
“I’m happy to be his friend and I wish him all the best.”
