After Gabriel Heinze announced he was leaving Olympique Marseille, Juventus have been linked with the veteran defender.
“There isn't just one reason why I decided to go, but I think this is the right choice and I did the club a favour by walking away,” said the 33-year-old former Manchester United man.
“I had extraordinary moments here, but this adventure is over.”
Juventus have immediately been linked with a swoop for Heinze, who had already been of interest in previous years.
There is stiff competition from the Premier League, where the Argentine is still well-known and respected.
