Arsenal lost 3-2 to Borussia Dortmund in the Emirates Cup final, exposing defensive frailties just seven days before the Community Shield against Manchester City in Cardiff. The Gunners trailed 2-0 at half-time after goals from Samuele Inacio and 18-year-old Konstantinos Karetsas.

Despite creating numerous chances, Arsenal's finishing let them down with Viktor Gyokeres hitting the bar. Ethan Nwaneri pulled one back after good work from Christos Tzolis, but comical defending at a corner allowed Joane Gadou to make it 3-1. Tzolis then won a penalty converted by Gyokeres, but Gabriel Martinelli's late equaliser was ruled offside.

New signing Bruno Guimaraes was unveiled before kick-off but couldn't prevent a second consecutive pre-season defeat conceding three goals. Since December 2023, Arsenal had only once shipped three in a match, but now face concerning habits with William Saliba injured and Jurrien Timber still out.

Positives emerged from Tzolis's sharp display, Martin Odegaard's creativity, and strong showings from youngsters Max Dowman and Nwaneri. Mikel Arteta must fix defensive holes before the Community Shield on August 16, with the full squad returning Monday.
