The 23-year-old had been quoted as saying that Arsenal lacked "maturity" and suggested that Wenger should be sacked for not winning silverware during his tenure at the club.
Speaking to reporters today, Mancini dismissed the article and claimed that Fabregas had been misquoted.
"The article bothers me," he said. "This was an article organised by the club with a check viewing of the article. Not only did the author not respect the agreement, but also he did twist completely the article and we are really upset about it."
He added: "It was not an attack on my philosophy. That is not what [Fabregas] said. He said completely the opposite."
Meanwhile, Fabregas wrote on Twitter: "Incredible that people try and twist everything to make headlines. Arsene Wenger has had a huge impact on me and my career. Great man."
