Laurent Koscielny says his job at the back is made easier by the presence of Alex Song in midfield.

Song returned to the Gunners’ starting line-up after missing the team’s last three league fixtures through suspension, and Koscielny believes the Cameroon international is a vital cog in the Arsenal machine.

Laurent, how pleased are you with the point?
It was a hard game, Dortmund played very well. We defended well, but to concede a goal two minutes before the end was difficult for us. We didn't lose, which was good. We have a game at home, and it is important to win that.

How much confidence can you take from your performance?
I think we defended very well - all the team defends together. It's very important to have Alex [Song] near the centre backs, because he stops the opportunities coming to the other team. It's good for us.

You go to Blackburn at the weekend, are Arsenal more confident now?
Yes, we are in a good place now and we want to go and win at Blackburn.
