The Denmark international is not in manager Arsene Wenger's plans at the Emirates and is widely expected to move on.
The 24-year-old spent last season on loan at Sunderland and Bendtner is happy to leave the Gunners in search of regular first-team football.
Bendtner insists talks are on-going with several interested parties and that he has already turned down offers from other sides.
"Arsenal is not an option and that is something both the club and I agree on," Bendtner told sporten.dk.
"I expect to have found a solution to my situation before the window closes. There are concrete negotiations in the works."
Asked if he had turned down some offers, Bendtner added: "Yes I have and there are a lot of different reasons for that.
"I have three demands and I won't sign a deal with a club who aren't prepared to fill those demands."
