Jürgen Klopp, Dortmund coach
Arsenal have a lot of new players in their squad. They have bought a lot of quality with players like Alexis Sánchez and Danny Welbeck. Arsenal did a very good job during the transfer window. They have stability and are able to play defensively now. Furthermore they have a lot of quality in the centre of midfield.

If you watched Arsenal here last year you will have noticed that they are very strong in defence with a good transition game. But we are not thinking about our previous matches against Arsenal. We draw conclusions from their last Premier League matches.

The Champions League begins now and it will be a tough start. We want to be as aggressive as we can. We have to concentrate on the main attributes you need when playing football. Then we will have to be tactically clever to nullify their way of playing. After doing that we can bring our own skills to the table. That will be a hard job for us tomorrow.

Arsène Wenger, Arsenal manager
I have great respect for Mr Klopp. He rose up very quickly in his career and inspired Dortmund. What does he do better than me? Maybe a lot of things. But I love to see his team playing dynamic and attractive football. I like it.

In defence we of course have the Mathieu Debuchy injury, but I don't feel we are stretched. The Debuchy injury put us in a position where we do not want more and hopefully we have good news after the scan today that he can be back soon. We have [Calum] Chambers who can play in different positions and Héctor Bellerín, who I think now is ready to play.

Bellerín is a boy with personality. He's not fazed by the pressure. That's important when you're a young boy. His transitional game is fantastic. He's quick and his final ball is good. He lacks a bit of experience but he's very dangerous.
