Arsène Wenger, Arsenal manager
I'm focused on tomorrow's game but of course it's a great honour and privilege to be in charge for such a long time of such a big club [Wenger marks 18 years as manager on Wednesday]. I have no time to look back. I will do it another time – but it's a great privilege. I just want to be [meeting] the expectations of this club and our job is the next game – to win it.

We had a disappointing result in Dortmund but at the moment I feel the potential is there. We don't lose a lot but we want to find the winning edge together and we have that opportunity tomorrow.

In the Champions League you want to win your home games. You need one good result away from home and you need to win your three home games.

We have plenty of options. I believe we have a strong squad and we want to use that during the course of the season.

Cesare Prandelli, Galatasaray coach
We are playing against a quality team with a lot of experience. In our own half we will try to play our own game. They will try to get at us and we must be focused and try to control the play as best we can. We know it will be a difficult game but we are confident. We have to do a lot of running every match. It's European football – we should be running, closing all the gaps.

Arsenal have big players missing but they have plenty of top-class players and we have to make sure we don't change our philosophy and play our own game. They have shown they can play football no matter who is on the pitch and as a big team we should also ensure we impose ourselves too. We will make sure that whenever we lose possession we win it back very quickly. We must be very brave.

All these experiences [like winning 2-1 at Arsenal in a summer friendly] boost your morale. It can also give you an advantage and additional confidence, but we have to be very brave and I believe we can always improve.
