Arsene Wenger will be hoping his side can register their first win in the Champions League this season with three points against Galatasaray.
The Gunners were well beaten in their first game away at Borussia Dortmund and will be hoping for a much more effective performance in all areas of their team this evening.
Several key players underperformed during that game and they need to step up if Arsenal are to get into a good position ahead of the first knock out round.
The build up for Wenger has seen his side frustrated by injuries to key players, but the team will be confident after a point in the North London derby against Tottenham last weekend.
Arsenal have the home advantage and will be looking to start the game quickly, as Galatasaray are more than likely going to setup looking for a solid performance at least a point.
