Before every Arsenal fixture, we’ll bring you a Scouting Report on the Gunners’ next opponents.
Former Arsenal midfielder Stewart Robson will give his pre-match view and you can get his post-match verdict in our Talking Tactics feature on Arsenal Player.
Arsène Wenger takes his side to Dortmund for their Champions League Group F opener on Tuesday so, to find out more about our German opponents, we also asked Ulrich Klose of RTL for his thoughts and analysis.
It's a massive game for Arsenal against the German champions and obviously they will want to go out and get another good result off the back of the win against Swansea. What Arsène Wenger will have to do, as he has many times in Europe before, is control the game and keep the crowd quiet. They will need to keep the ball and keep steady in possession. I don't think the Germans will actually press them that high up the field. It may well be a slow-tempo game, which will suit Arsenal. I think Wenger would be happy with a point. He still has to bed the team in and work with them in training to make sure they have a better understanding. But there's no doubt Arsenal can go and win this.
ULRICH KLOSE, RTL
Dortmund have a special history in German football. Everyone in Germany is proud that they are back in the Champions League for the first time in eight years. This game sold out in just four hours and everyone is very excited. They will be absolutely going to win the game because you need to win your home games if you want to go through the Group Stages. Dortmund have a young team and are very ambitious. They are fast, strong and have very good players like Mario Gotze.
