Arsenal suffered another setback in their pre-season campaign, losing 2-3 to Borussia Dortmund in the Emirates Cup at the Emirates Stadium. Despite Mikel Arteta's emphasis on improving defensive standards following a previous defeat to Real Betis, the Gunners struggled once again, finding themselves 2-0 down at halftime.

Samuele Inacio opened the scoring for Dortmund in the 7th minute, capitalizing on a pass from Lukas Nmecha. Just 22 minutes later, Konstantinos Karetsas doubled the lead after a defensive lapse from Arsenal.

Arsenal had their share of chances, including a notable effort from Viktor Gyokeres, who hit the bar. They managed to pull one back in the 55th minute when Ethan Nwaneri scored following an assist from the impressive Christos Tzolis.

However, defensive mistakes continued to haunt Arsenal, as a corner led to Joane Gadou scoring Dortmund's third goal in the 59th minute. Gyokeres converted a penalty in the 69th minute after Tzolis was fouled by Jobe Bellingham.

Key moments included:

• 7': Inacio scores for Dortmund.
• 29': Karetsas extends the lead.
• 55': Nwaneri pulls one back for Arsenal.
• 59': Gadou restores Dortmund's two-goal cushion.
• 69': Gyokeres scores from the penalty spot.
• 90+4': Gabriel Martinelli's potential equalizer is ruled offside.

With just a week before their Community Shield clash against Manchester City, Arteta faces urgent defensive challenges to address. New signing Bruno Guimaraes featured before kickoff, highlighting the need for reinforcements as the season approaches.
