The 31-year-old, who is nearing the end of his current deal with the Gunners, has been heavily linked with a move to the Premier League champions over the past few months.
However, the full-back has rejected speculation that he has already agreed a switch to the Etihad Stadium ahead of the new season.
"Have I already signed a contract with Manchester City? No, that is not true," the France international told Telefoot.
"My situation will be sorted out before the World Cup, but I haven't signed for anyone so far. We all have our own destiny and I will try to find mine."
Sagna joined Arsenal from Auxerre in 2007.
