What's behind Arsenal's 3-2 loss to Borussia Dortmund?
Three goals conceded in consecutive pre-season matches have given Arsenal a defensive problem to solve just days before their competitive schedule begins. Borussia Dortmund beat the Gunners 3-2 at Emirates Stadium on August 9, with Samuele Inacio, Konstantinos Karetsas and Joane Gadou scoring for the visitors. Ethan Nwaneri and Viktor Gyokeres responded for Arsenal, but a late Gabriel Martinelli effort was ruled out for offside.

What Is Happening
Arsenal fell two goals behind before half-time. Inacio opened the scoring after being played through by Felix Nmecha, while Karetsas doubled Dortmund's advantage after Arsenal lost possession near halfway. Arsenal created opportunities of their own, including a Viktor Gyokeres attempt that struck the crossbar.
Nwaneri reduced the deficit early in the second half after Christos Tzolis supplied the cross from the left. Dortmund quickly restored their two-goal cushion when a corner produced a goalmouth scramble and Gadou applied the final touch.
Tzolis then won a penalty, allowing Gyokeres to make it 3-2 in the 69th minute. Martinelli appeared to have found a late equalizer, but the goal was disallowed for offside.
The Background
The result matters because Arsenal's defensive difficulties have now appeared in successive matches. The team had already lost 3-1 to Real Betis on August 5. According to Sky Sports, Arsenal had conceded three goals in a match only once since December 2023 before this pre-season sequence, but have now allowed three against both Betis and Dortmund.

There were personnel considerations. Martin Odegaard was making his first pre-season appearance after returning from the World Cup and was replaced by Nwaneri after roughly half an hour. Gabriel Magalhaes was also making his first start of pre-season following his return.
- Emirates Cup
- Arsenal's pre-season competition at Emirates Stadium.
- Pre-season
- Preparatory matches played before the competitive domestic campaign begins.
The Latest Development
The loss placed extra attention on Arsenal's defending because their next competitive fixture is the Community Shield against Manchester City in Cardiff on August 16. Before that, Arsenal host Como on August 12 in their final pre-season friendly.
There were encouraging attacking signs despite the defeat. Tzolis assisted Nwaneri and won the penalty converted by Gyokeres. Max Dowman, 16, also created a first-half opportunity for Gyokeres that ended with the striker hitting the bar.
Nwaneri had an especially productive afternoon. Beyond his goal in normal time, he scored the decisive penalty in a pre-planned shootout held after the match, which Arsenal won 5-4. Several academy players also received minutes late in the game, including Theo Julienne, Josh Ogunnaike, Ceadach O'Neill and Ife Ibrahim.
What It Means
The immediate issue for Arsenal is less the pre-season trophy than the pattern behind the goals. Dortmund found space for their opener, Karetsas punished a turnover for the second, and Gadou's goal followed trouble clearing a corner. Those different routes to goal give Arsenal several defensive situations to address before Manchester City.
At the same time, the match offered evidence of attacking depth. Tzolis directly influenced both Arsenal goals, Nwaneri made an impact after replacing Odegaard, and Dowman repeatedly threatened from wide areas. Gyokeres also reached dangerous positions, although his first-half finishing prevented Arsenal from capitalizing earlier.
For Canadian supporters following the Premier League season, the larger question is how quickly Arsenal can tighten those defensive moments before competitive football begins. The club's league opener is scheduled for August 21 at home against newly promoted Coventry City.
What Remains Unclear
The sources establish Arsenal's defensive problems across the Betis and Dortmund matches, but they do not establish whether those problems will persist once more senior players return. The Dortmund game was still a pre-season fixture with Arsenal using numerous substitutions and academy players.
What is confirmed is the timetable: Como comes next on August 12, followed by Manchester City in the Community Shield four days later. Those matches will provide the next evidence of whether Arsenal can correct the errors that allowed six goals across their two latest defeats.
