The Argentina international has revealed that Roberto Mancini wanted him at the Etihad Stadium before he made the £24m move to Paris.
The 27-year-old said that he joined the French side due to the city he would be living in, claiming that Paris is a much better place to live than Manchester.
"When two clubs are as ambitious as one another, that is what will make the difference - the city where you live," he said.
"This is the reason that made me choose Paris. For life outside football, I think that Manchester has nothing in common with Paris. I am already settled in here, in a house in Neuilly-sur-Seine.
"For me, personally, to have signed in Paris is a beautiful challenge. It's a short-term project - win major trophies, including the UEFA champions League."
Lavezzi made 188 appearances for Napoli, scoring 48 goals in his time at the club.
