Arsenal 2-3 Borussia Dortmund: Mikel Arteta's side defend poorly but Christos Tzolis shines as Gunners lose Emirates Cup

Arsenal produced more comical defending in pre-season as Borussia Dortmund won 3-2 in north London to win the Emirates Cup.

After Mikel Arteta said Arsenal's defending in Wednesday's defeat to Real Betis was "below the standard", the Gunners found themselves in trouble again as they were 2-0 down at the break thanks to goals from Samuele Inacio and 18-year-old wonderkid Konstantinos Karetsas.

Arsenal had plenty of chances throughout - with the wasteful Viktor Gyokeres hitting the bar in the first half - and while Ethan Nwaneri pulled one back after good work from Christos Tzolis, a calamitous corner allowed Joane Gadou to make it 3-1.

Tzolis then capped off a promising performance by winning a penalty which Gyokeres converted. But with seven days to go until their Community Shield game with Man City in Cardiff, Arteta has some holes to fix.

Arsenal welcomed new signing Bruno Guimaraes onto the Emirates pitch before kick-off - he is needed sooner rather than later.

"We lost the game, obviously not happy about it. Things obviously have to be improved. Certain players need to get more minutes and rhythm, which is going to be really helpful.

"It has to hurt, whether it is a friendly match, a test or whatever you want to call it. But yeah, we know where we are. We know that we are missing still a lot of players and some players that haven't had enough training. And yeah, sometimes it [losing] is good.

"We conceded some poor goals the other day, some poor goals today, in the way we competed, especially. But that's a very collective responsibility. So, we need to improve with the players that we have. And we want to improve, for sure we will."
