Tough for OM, Napoli, Dortmund, Arsenal

Arsène Wenger, Arsenal manager
It's difficult but exciting as well because it's a group of a very good level. We have played Dortmund two years ago. We did well against them and Napoli did well last year. Marseille we played two years ago as well. It's a similar group to what we knew two years ago. Every game will be of huge importance because it could be down to a point or goal difference in the end.

Mathieu Valbuena, Marseille forward 
I'm disappointed because we played Dortmund and Arsenal already two years ago. They are two good teams. I've kept an eye on Napoli's transfers this summer. It's three nice trips in terms of the atmospheres. Clearly, though, you can speak about the group of death. Advancing from this would be exciting. We would be proud to do it.

André-Pierre Gignac, Marseille forward
A high-class draw for sure! Nice stadiums, great teams and great games for us to play and win.

Jürgen Klopp, Dortmund coach
It's a great, well-balanced group with four teams that have what it takes to get through. The fact is, we have something to make up for against both Arsenal and Marseille. I have never been to Naples but I'm looking forward to the atmosphere there. It's going to be very exciting

Rafael Benítez, Napoli coach
When you talk about the Champions League, then you know that all groups are tough. Ours is one of the most even. Certainly it will be difficult because we will be facing teams who have great experience in the Champions League. It will be a great challenge for us.

Dortmund are a top club, they reached the final last season and play great football. We have faced Arsenal recently in London [for a pre-season friendly] so we know them well .They have a great manager, who is very experienced at European level. Against Marseille I had my first success in Europe, the UEFA Cup final with Valencia [in 2004]. It won't be easy in their stadium because their fans are very passionate.
