The Swede swapped AC Milan for the French capital last summer and promptly led Carlo Ancelotti's side to the Ligue 1 title, but has since been linked with a move back to former club Juventus.
"Will I stay at PSG? We'll see. A lot of things can happen," he is quoted as saying by La Gazzetta dello Sport. "All the times [in the past] that I have said that I would be staying, at the end I changed clubs. This time I am not going to say anything. I still have two more years left on my contract but anything can happen. I have changed teams several times and then I planned to stay at a single club for a long time but it did not happen."
The big forward then went on to say that the culture in Italy makes a move back to Serie A attractive.
"I miss Italy. It's my second home," he said. "The clubs I've played for, Juventus, Inter and Milan are the biggest in the world, I won with them and I know what it means to be a footballer in Italy. There is is a big difference, Italy is the most fanatical about football. Italians are used to big football stars and when they arrive they treat them in a certain way.
"If you play for a big club and go out to eat the owner of the restaurant tells you: 'My restaurant is yours'. It's not like that in Spain. There are different cultures and the Italian one is the one I like a lot."
