The temptation for Cologne is going to be to try and go for this match in order to kick start their season. And rightly so. They know that Arsenal are weak and that they can seriously take advantage of their depressed mood right now to boost their own.
But it will not be an easy feat, still, as the Gunners have a ton of quality players in their side. Just what side Arsene Wenger decides to go with will determine the result, but it's hard to see anything but an Arsenal win right now.
