Sagna has made 69 appearances for City since signing in 2014, but he has revealed that the club are yet to approach him over potentially extending his stay at the Etihad Stadium.
The 33-year-old told beIN Sports: "My contract expires at the end of the season. I am not thinking about it, though. I just take things as they come and try to give my all.
"There have been no negotiations as of yet, so I do not know what will happen."
Sagna has recently been linked with a transfer to Marseille in the summer.
