The 26-year-old striker admitted that he does not plan to remain at the Emirates Stadium beyond this summer due to his desire for regular playing time.
And Olsen, his national coach, agrees:
"I don't want him to go away from Arsenal, him playing there is fantastic, but he has to," the 64-year-old Denmark boss told reporters.
"But now he's in his middle-20s and he needs regular football now."
Indeed, Olsen's main drive behind urging Bendtner to leave London does not seem to be a lack of confidence in his lead striker - but rather a strong feeling that he can succeed elsewhere.
"We saw in the European Championship in 2012 when he is physically ready he is a very good player - but he has to play," the 64-year-old continued.
"I think if he plays at the right place and he's physically 100 per cent, he can play in many places.
"Now he is coming to Arsenal when he was 16 but he has to decide that maybe with eight years to go.When he's 35 I hope he will be able to sit and say the last eight years were the best of my football life."
Olsen is wary, though, that the 26-year-old has sometimes had too much confidence in his own ability.
"That [confidence] has not always helped him but I think it's a learning process, somebody takes a year more or two than others.
"You need confidence to survive in top football but you have to take it step by step.
"For such a player, you have to play games, games, games. We know what he can do when he's in top condition."
Should Bendtner leave the Gunners at the end of the season?
