Arsene Wenger will be concentrating on tonight's clash with Borussia Dortmund but the Frenchman will have one eye on a number of January transfer targets also in action this week.
Arsenal can secure their place in the knockout phase of the Champions League with a draw at home to the German champions.
Wenger will use tonight's game to scout January targets Mario Gotze and Shinji Kagawa, two of Europe's brightest young prospects who have regularly been linked with a move to the Gunners.
The Arsenal manager is in the market for a creative midfielder following the departures of Samir Nasri and Cesc Fabregas in the summer.
Dortmund's Neven Subotic and Lille midfielder Eden Hazard have also been linked with moves to Arsenal, while Real Madrid's Raul Albiol is another transfer target.
With this in mind, IBTimes Sports takes a look at the players who Arsenal will be keeping tabs on tonight as they look to progress in Europe.
