The Gunners earned a reputation for giving academy stars opportunities under previous boss Arsene Wenger.
Players such as Hector Bellerin, Alex Iwobi and Ainsley Maitland-Niles have all broken though in recent seasons.
But Cohen Bramall, who joined Arsenal in January 2017, was never given a chance by Wenger or Emery.
The left-back was released by the club at the end of last season and he believes Arsenal must give more youngsters a chance next year.
Yes, 100 per cent,” said the defender, when asked by Goal if there was a chance of the Gunners losing some of their top talent.
“If they don’t get the chance to show how good they are they will go abroad.
“There are a lot of clubs in the Bundesliga who want English talent and they will jump ship and go and try it over there.”
Arsenal sent Reiss Nelson and Emile Smith Rowe on loan to Bundesliga clubs last season where they had varying degrees of success.
Calum Chambers has been recalled after earning plaudits at Fulham, while Krystian Bielik also performed well at Charlton.
Emery refused to allow striker Eddie Nketiah to leave on loan in January, but the 20-year-old was given little time to prove himself on the pitch for the Emirates outfit.
“I feel sorry for Ed because Danny was injured for a lot of the season and Ed should have been given more chances,” Bramall continued.
“But with the media and the fans, there is a lot of pressure on youngsters because as soon as they don’t have the best game, people are on to them.
“It’s hard to take in. But with Ed, the boss should have given him more chances.
“The first team were in a difficult position last year, though, obviously trying to get Champions League and the fact it was Unai’s first season made it hard for youngsters to get in.”
Two of Arsenal’s best emerging talents are Xavier Amaechi and Tyreece John-Jules, who have yet to make their senior competitive debuts.
Goal claim that Bayern Munich want to sign 18-year-old winger Amaechi, while striker John-Jules is wanted by a host of top sides across the continent.
