The big-spending French club went on a spending spree in the most recent transfer window and bolstered their squad with the likes of Zlatan Ibrahimovic.
The right-back, 29, has refused to rule out a future move to Parc des Princes but insists that it would depend on his no longer being wanted at Camp Nou.
"It is true that PSG has called many people and built a beautiful project," he told RMC on Thursday.
"This summer, they spoke to my representatives and consulted to see if they could do a transfer.
"But the possibility was very low because my price was very high and suddenly they turned to other players.
"As to whether I could play in Paris, you never know what the future holds, and I don't have to close doors. If one day, Barca do not want me anymore [then who knows]."
