The 23-year old says that another season like the one he just experienced would almost certainly drive him to an Emirates Stadium exit.
"I can promise that there won't be another season like this one," Bendtner told sporten.dk.
"I have decided 100 per cent that I must leave Arsenal.
"I've considered this for a long time and was quite clear when I arrived at my decision.
"I'm quite calm and confident that I'll be fine at a new club."
