Arsenal's defense: a horror show. Dortmund bags Emirates Cup.

First half. Pure calamity. Gunners were behind before the popcorn cooled. Samuele Inacio got things rolling for Dortmund in the seventh minute. Lukas Nmecha set him up. Then 18-year-old Konstantinos Karetsas put on a solo show. Doubled Dortmund's lead. All thanks to Riccardo Calafiori's terrible pass at midfield. Gift wrapped.

Sure, Arsenal carved out chances. Viktor Gyokeres smashed one off the bar from the right wing. But converting them? Nope. Story of the game.

Ethan Nwaneri did pull one back after the break. Christos Tzolis with the assist. Gave 'em a glimmer. Then, *poof*. Gone. A corner routine, frankly, was an absolute shocker. Joane Gadou capitalised. Dortmund up 3-1. Just brutal to watch.

Gyokeres converted a penalty. Tzolis earned it. Now 3-2. The home crowd tried to believe. But that was it. No equaliser. Alejandro Martinelli thought he had one late. Offside. Of course.

This isn't an isolated incident. Two pre-season losses in a row now. Arteta already sounded off after the Real Betis defeat on Wednesday. Called the defending 'below the standard.' You think?

New signing Bruno Guimaraes got introduced before kick-off, per Sky Sports. Timing couldn't be better. Or worse. Arteta needs help. Fast. Manchester City looms in Cardiff on 16 August. The clock's ticking.
