Arsenal’s pre‑season performance turned into a comedy of errors as Borussia Dortmund secured a 3-2 victory at the Emirates Stadium to claim the Emirates Cup. After manager Mikel Arteta publicly criticised his side’s defensive display in the 2-1 loss to Real Betas, the Gunners found themselves in a similar predicament just a few days later, trailing 2-0 at the interval thanks to strikes from Samuele Inacio and 18‑year‑old prodigy Konstantinos Karetsas. Despite creating a multitude of opportunities – Viktor Gyökeres, for instance, hammered a shot straight onto the cross‑bar in the first half – Arsenal’s inability to finish and their porous back line proved costly.

Ethan Nwaneri managed to pull one back after a well‑timed pass from Christos Tzolis, but a disastrous corner allowed Joane Gadou to restore Dortmund’s three‑goal cushion. Tzolis, who had a promising afternoon, later earned a penalty that Gyökeres calmly slotted, reducing the deficit to 3-1. Yet with just a week left before the Community Shield clash with Manchester City in Cardiff, Artetta knows there is still a great deal of work to be done.

The match also marked the first appearance of new signing Bruno Guimarães on the Emirates pitch. The Brazilian midfielder’s introduction was eagerly anticipated, and his early involvement underscores the urgency with which Arteta wants him integrated into the squad.

**Key moments of the game** - 7′ Inacio opened the scoring after being released into the box by Lukas Nmecha. - 15′ A potential penalty for Arsenal was denied when referee Chris Kavanagh initially pointed to the spot after Martin Ødegaard was brought down, only to reverse his decision and award a free‑kick on the edge of the area, which Gyökeres struck over the bar. - 26′ Gyökeres again rattled the post following Ødegaard’s pass that found Dowman on the right wing.

- 29′ Karetsas doubled Dortmund’s lead after Riccardo Calafiori lost possession on the halfway line, prompting a solo run. - 43′ Tzolis produced two impressive free‑kicks within four minutes, but Gabriel’s header went over and Havertz’s attempt was straight at the goalkeeper.

- 55′ Nwaneri narrowed the gap, finishing a move set up by Tzolis on the left. - 59′ A poorly defended corner saw Gadou score the third for Dortmund after Illan Meslier could not keep Calafiori’s delivery out of the danger area. - 69′ Gyökeres converted a penalty after Tzolis was fouled by Jobe Bellingham. - 90+4′ Martinelli thought he had equalised, but the goal was ruled out for off‑side from a short corner.

Arteta’s post‑match comments were blunt: “We lost the game, obviously not happy about it. Things have to improve. Some players need more minutes to find rhythm, which will be helpful. It hurts, whether it’s a friendly or a test, but we know where we stand.

We’re still missing several players and some haven’t had enough training. Losing can be good – it highlights the areas we must fix. We conceded poor goals today, and that’s a collective responsibility.

We will improve with the squad we have.” Sky Sports’ correspondent Sam Blitz highlighted a worrying statistic: since December 2023 Arsenal had only once allowed three goals in a match – a 3‑2 defeat to Manchester United in January that ended a 121‑game streak of conceding fewer than three. Now, back‑to‑back pre‑season fixtures have seen them concede three goals in consecutive games, a scenario last witnessed in April 2023 when they drew 3‑3 with Southampton and then lost 4‑1 to Manchester City in a title‑deciding encounter. While the pre‑season context tempers the criticism, the defensive frailties are evident. With eight first‑team regulars still absent – including the likes of Declan Rice and the newly arrived Bruno Guimarães – the back line has struggled to maintain its usual compactness.

The injury to William Saliba and the ongoing recovery of Jurrien Timber exacerbate the problem, leaving the defence unusually exposed. Of the six goals conceded across the Betis and Dortmund friendlies, three came from long‑range efforts and two resulted from poorly defended set‑pieces. The club’s transfer activity suggests Arteta is aware of the need for reinforcement. Interest has been reported in centre‑back Ezri Konsa and a potential high‑profile move for Tottenham captain Cristian Romero, indicating that strengthening the defensive unit is a priority.

Nevertheless, there were positives to take away. Christos Tzolis impressed with his creativity, Ødegaard generated numerous chances in open play, and young talents Max Dowman and Ethan Nwaneri showed resilience by contributing both offensively and defensively. Looking ahead, the Gunners will have a full squad available for the first time on Monday as World Cup winners and England internationals return from international duty.

The upcoming Community Shield against Manchester City will serve as a crucial barometer for the squad’s readiness and may set the tone for the forthcoming Premier League campaign. **Upcoming fixtures** - July 25: Arsenal 3‑0 MK Dons (training ground) - August 1: Girona 1‑4 Arsenal - August 5: Arsenal 1‑3 Real Betis (Dublin) - August 9: Arsenal 2‑3 Borussia Dortmund - August 12: Arsenal vs Como (Emirates Stadium, 19:30) - August 16: Community Shield – Arsenal vs Man City (Cardiff, 15:00) The pre‑season may have exposed some unsettling habits, but with a full complement of players soon to be back and potential defensive signings on the horizon, Arsenal have the tools to tighten up and avoid the “poor goals” that have plagued them in recent friendlies.
