The Danish forward, 23, has been on the bench for most of the season and has only managed two goals from his 14 appearances.
"It is incredibly frustrating not being seen as a first-team player, but there is not much I can do about it," Bendtner told Danish tabloid Ekstra Bladet. "I have proven that I am good enough to play from the start at Arsenal.
"[Robin] van Persie is ahead of me at the moment and there is nothing to say about that because he has scored 16 goals since New Year."
Bendtner added that he would wait until "after" the end of the season to "decide on my future, but not before".
