Arsenal have announced their released list, with seven youngsters set to leave the club when their contracts expire at the end of this month, including goalkeeper Hugo Keto.
Fellow shot-stoppers Ryan Huddart and Alex Crean have also been let go.
In addition defenders Tafari Moore, Marc Bola and Chiori Johnson are also departing along with winger Aaron Eyoma.
Keto joined Arsenal four years ago and the Finland youth international produced some impressive performances at youth level, demonstrating his excellent reflexes.
However, he found it difficult to break into the first-team squad with both Matt Macey and Deyan Iliev ahead of him, a problem also encountered by Huddart.
Huddart was named on the bench for two Champions League games against Anderlecht as a 17-year-old but was rather phased out last season as he barely featured.
Crean, another goalkeeper, arrived at Arsenal in 2016 but struggled to establish himself in the U18s, mainly due to the excellent displays of Joao Virginia.
The departures of Johnson and Eyoma have been inevitable for some time, with both players having been sent on various trials in the second half of last season.
Bola gained experience while on loan at Bristol Rovers and Notts County, while he was on the bench for the Arsenal first-team in the League Cup, but leaves in search of regular football elsewhere.
Moore produced some encouraging displays on loan at Wycombe Wanderers but he was never going to realistically challenge Hector Bellerin for a place in the starting lineup for the first-team.
