Arsenal boast a number of quality youngsters within Mikel Arteta’s squad. But in years gone by, the Gunners have had their fair share of mistakes when deciding on a player's future.
Bukayo Saka, Gabriel Martinelli and William Saliba are all perfect examples of young players making the grade at the club. All three have played starring roles for Mikel Arteta's side this season and are expected to be front and centre for years to come.
But on the other end of the scale there have been some that have been allowed to leave, only to impress at their new clubs. Serge Gnabry has made over 200 appearances for Bayern Munich since leaving the Gunners in 2016 and there is now another ex-Arsenal star catching the eye.
