We need to try and catch them on the break if possible. It might be a good idea to take the sting out of this game by making some changes or keeping the ball a little bit.
That goal has given us the confidence... and has slightly deflated Dortmund. Arsenal are showing their experience here. We just need to keep the ball.
We're 1-0 up against (imo) the best team in Europe away from home. We need Giroud to stay on for his hold up play.
