Edu said he was leaving to pursue “a different challenge” but did not specify what that would entail.

“This was an incredibly hard decision to make,” Edu said in a club statement. “Arsenal has given me the opportunity to work with so many amazing people and the chance to be a part of something so special in the club’s history. … Now it is time to pursue a different challenge. Arsenal will always remain in my heart. I wish the club and its supporters only good things and all the very best.”

Arsenal co-chair Josh Kroenke said the club respected Edu’s decision and noted his “immense contribution and dedication to drive the club forward.”

Kroenke added: “Change and evolution is a part of our club. We remain focused on our strategy and winning major trophies. Our succession plan will reflect this continued ambition.”

Edu played 127 times for the Gunners and featured in Arsene Wenger’s “Invincibles,”who went the entire 2003-04 season unbeaten.
