Arsenal hero Ray Parlour believes Pierre-Emerick Aubameyang will leave if they fail to qualify for the Champions League.

The Gunners' captain is unsettled at the club as he enters the final year of his contract, and holds concerns over whether Arsenal can match his ambition.

"If they [Arsenal] can come back and hit the ground running and get a good start to the season, obviously the Man City game is going to be very important, if they can get anything out of that game that will give them a lot of confidence going forward," said Parlour.

"Champions League football is so important for a lot of players these days so Aubameyang, if they can squeeze in there, might sign a new contract, I don't know.

"If they don't, then he might be on his way and suddenly you've got to replace a striker who scores all your goals."
