Sagna's future at Arsenal has been the subject of conjecture for some time with the full-back out of contract this summer.
Contract talks have stalled with Arsenal boss Arsene Wenger recently claiming there had been no progress on the discussions and that Sagna had a decision to make.
Sagan has now confirmed contract talks have hit a snag and that he was likely to leave the Emirates this summer.
"I'm out of contract, as everyone knows," Sagna is quoted as saying to europe1.fr. "I still consider myself as an Arsenal player at present.
"But actually we had a small problem to agree (a new deal), and I don't think I stay at Arsenal at the end of the season."
The likes of Manchester City and Chelsea have been credited with an interest in Sagna with the French international thought to be keen to stay in the Premier League.
Sagna joined Arsenal from Auxerre in July 2007 and has established himself as a key member of Arsene Wenger's side.
