Manager Mikel Arteta insists Arsenal's "very ambitious" vision will continue despite the exit of Edu as the club's sporting director.
The Brazilian resigned on Monday after two years in the role, having initially rejoined the Gunners as technical director in the summer of 2019.
Edu, 46, played for Arsenal between 2001 and 2005 and won two league titles, with one coming as part of the 'Invincibles' team of 2003-04.
He has been widely credited with helping to transform the club back into genuine title challengers, but Arteta is confident that Arsenal will continue on the same path without him.
