Zabaleta made 42 appearances in all competitions for City last season, but is thought to be unsure over his long-term future at Eastlands under new manager Manuel Pellegrini.
With negotiations over a new City deal underway, the Argentine has conceded that a switch to Serie A remains possible, welcoming interest from any of Italy's leading clubs.
He told SportItalia: "Serie A is a major championship. It's certainly a League I'd like to play in.
"A team? I consider Fiorentina to be an interesting team. I have always liked them since the days of Gabriel Batistuta.
"Juventus, Milan and Inter are big clubs though."
The 28-year-old has spent five seasons with City in the Premier League, after making a £6.45m move from Real Zaragoza in 2008.
