Arsenal are heading into this one after a couple of mixed results. They picked up a win, but that was followed by a heavy loss and a draw, so they're not exactly in red-hot form. On the other hand, Borussia Dortmund are in a tough patch. They have lost four of their last five games, which suggests they are really struggling to find their footing right now. Dortmund's only recent win came away from home, so they might feel a bit more comfortable on the road.

Looking at how these two are playing, Dortmund have been involved in some higher-scoring games lately, with both teams trading goals. Since we don't have any recent head-to-head meetings to go on, this feels like a pretty open contest. Given that both sides have shown they can be unpredictable, this match looks very close to call. It wouldn't be a surprise to see the game end in a draw, as neither team looks strong enough to dominate the other completely.
