Arsenal have begun the process of searching for new Under-23 and Under-18 head coaches.
U23s boss Kevin Betsy left the club on Monday to takeover at League Two side Crawley Town, taking U18 coach Dan Micciche as an assistant.
And the London Evening Standard says the club could look internally to fill the positions.
"We're grateful for the work Kevin and Dan have done to manage and develop our Under-23s and Under-18s," said academy director Per Mertesacker on Monday.
"Both have shown outstanding coaching ability so it's no surprise they're heading into first-team management in the EFL.
"This is a great opportunity for them, and on behalf of everyone at Arsenal, I'd like to thank them for their service and wish them the very best of luck in the future."
