The Danish international joined the Gunners in 2004 but has since failed to establish himself in the club's starting lineup.
That has resulted in a number of loan spells and while discussing his future, the 24-year-old has hinted that the time could be right for him to leave the Emirates Stadium on a permanent basis.
"It's difficult. I feel a lot of things for Arsenal, most good things. I left, not on bad terms but not on great terms," he told Sky Sports News.
"At the moment, my future is here at Juventus. Beyond that, it can lie at Arsenal or elsewhere. It's not 100% decided. But my focus is on Juventus."
Bendtner has also had loan spells with Birmingham City and Sunderland.
