The Denmark international spent last season on loan at Sunderland but has no plans to return to the Stadium of Light or Emirates Stadium.
Bendtner did not do badly in advertising himself at Euro 2012, where he scored twice in the 3-2 defeat against Portugal.
The 24-year-old's agent, Jesper Lynghus, now claims a number of clubs from around the world have been showing interest.
Speaking to Danish newspaper bold.dk, Lynghus said: "The interest is overwhelming, just as it should be after the way Nicklas performed at Euro 2012.
"We are getting closer day by day.
"We are not commenting on individual deals at the moment, but it is fair to say the interest in Nicklas is global."
