In 2004, Carini left Juventus for Internazionale, when he was exchanged for Fabio Cannavaro in a transfer which was worth €10 million. Despite being the first choice goalkeeper for his country, Carini was the third choice goalkeeper for Inter. After spending the 2005–06 season on loan at Cagliari, he went back to Inter, where he became the fourth goalkeeper behind Francesco Toldo, Júlio César and Paolo Orlandoni. Carini did not see a single minute of action over the next two years, a period during which Inter won the Serie A title in 2007. Before the 2007–08 season, he moved to newly promoted Spanish club Murcia to compete with incumbent first-choice goalkeeper Antonio Notario. He signed a three-year deal with the Brazilian club Atlético Mineiro in 2008, arriving on a free transfer. Atlético Mineiro rescinded Fabián Carini's contract in 2010; as a result, they had to a penalty to him, as his contract with the club ran until 2011.
